+description: CMake target-based design conventions for OVR (no catchall include paths, no self-referencing link lists)
+globs: **/CMakeLists.txt,**/*.cmake
+alwaysApply: false
+---
+
+# CMake target-based design
+
+OVR's build is target-driven: every dependency should expose a CMake target
+that carries its own include directories, compile definitions, sources, and
+link dependencies. Avoid broad include shims such as `${repo}/extern`.
+
+## No catchall `extern/` include paths
+
+```cmake
+# BAD - sweeping include path that resolves <X/Y.h> to whatever happens to
+# live under extern/X/. Order-dependent, fragile when deps overlap (e.g.
+# both tinygltf and stb bundle stb_image.h).
+target_include_directories(rendercommon PUBLIC
+  $<BUILD_INTERFACE:${CMAKE_CURRENT_SOURCE_DIR}/../extern>
+)
+
+# GOOD - each external dep owns its include path on its own target.
+# Consumers link the target; the include path propagates.
+target_link_libraries(rendercommon
+  PUBLIC tfnmodule           # carries <tfn/X.h>
+  PRIVATE stb tinyexr        # carry <stb_image.h>, <tinyexr.h>
+)
+```
+
+## Header layout mirrors include style
+
+When a local helper target is consumed via `<libname/X.h>`, mirror that in the
+filesystem so the target's own dir is the include root. Avoid `..` traversal in
+INTERFACE include directories.
+
+```
+extern/glfwapp/
+├── CMakeLists.txt              ← exposes ${CMAKE_CURRENT_LIST_DIR} as PUBLIC include
+└── glfwapp/                    ← matches the include prefix
+    ├── GLFWApp.h
+    └── camera_frame.h
+```
+
+## Don't put a target in a list it itself consumes
+
+```cmake
+# BAD - glfwApp PUBLIC-links ${GFX_LIBRARIES}, which contains glfwApp.
+# Self-referencing list, also forces imgui (also in GFX_LIBRARIES) to link
+# its own consumer.
+list(APPEND GFX_LIBRARIES glfwApp)
+target_link_libraries(glfwApp PUBLIC ${GFX_LIBRARIES})
+
+# GOOD - GFX_LIBRARIES is the lower-level set (gl, glfw, glad, imgui).
+# glfwApp consumes them; consumers of glfwApp link glfwApp directly.
+```
+
+## Namespace-scope FetchContent'd deps when they bundle conflicting headers
+
+If an upstream bundles private copies of headers we also provide independently
+(e.g. tinygltf bundles `stb_image.h` and `json.hpp`), do not expose the
+upstream root directly. Mirror it under `build/<dep>_compat/<dep>/` and expose
+only `build/<dep>_compat/`. Consumers then include `<dep/header.h>` while the
+upstream's quote-includes still resolve to its private bundled copies.
+
+## Use `SKIP_RETURN_CODE` for feature-probe fixtures
+
+CTest fixture-setup tests that may legitimately fail on hosts lacking a feature
+(e.g. `gpu_probe` on a no-GPU CI runner) should set `SKIP_RETURN_CODE` so the
+probe reports Skipped, not Failed. Dependent tests still skip through
+`FIXTURES_REQUIRED`; `ctest` itself stays green on expected no-feature hosts.

+
+# Karpathy behavioral guidelines
+
+Behavioral guidelines to reduce common LLM coding mistakes. Merge with project-specific instructions as needed.
+
+**Tradeoff:** These guidelines bias toward caution over speed. For trivial tasks, use judgment.
+
+## 1. Think Before Coding
+
+**Don't assume. Don't hide confusion. Surface tradeoffs.**
+
+Before implementing:
+- State your assumptions explicitly. If uncertain, ask.
+- If multiple interpretations exist, present them - don't pick silently.
+- If a simpler approach exists, say so. Push back when warranted.
+- If something is unclear, stop. Name what's confusing. Ask.
+
+## 2. Simplicity First
+
+**Minimum code that solves the problem. Nothing speculative.**
+
+- No features beyond what was asked.
+- No abstractions for single-use code.
+- No "flexibility" or "configurability" that wasn't requested.
+- No error handling for impossible scenarios.
+- If you write 200 lines and it could be 50, rewrite it.
+
+Ask yourself: "Would a senior engineer say this is overcomplicated?" If yes, simplify.
+
+## 3. Surgical Changes
+
+**Touch only what you must. Clean up only your own mess.**
+
+When editing existing code:
+- Don't "improve" adjacent code, comments, or formatting.
+- Don't refactor things that aren't broken.
+- Match existing style, even if you'd do it differently.
+- If you notice unrelated dead code, mention it - don't delete it.
+
+When your changes create orphans:
+- Remove imports/variables/functions that YOUR changes made unused.
+- Don't remove pre-existing dead code unless asked.
+
+The test: Every changed line should trace directly to the user's request.
+
+## 4. Goal-Driven Execution
+
+**Define success criteria. Loop until verified.**
+
+Transform tasks into verifiable goals:
+- "Add validation" → "Write tests for invalid inputs, then make them pass"
+- "Fix the bug" → "Write a test that reproduces it, then make it pass"
+- "Refactor X" → "Ensure tests pass before and after"
+
+For multi-step tasks, state a brief plan:
+```
+1. [Step] → verify: [check]
+2. [Step] → verify: [check]
+3. [Step] → verify: [check]
+```
+
+Strong success criteria let you loop independently. Weak criteria ("make it work") require constant clarification.
+
+---
+
+**These guidelines are working if:** fewer unnecessary changes in diffs, fewer rewrites due to overcomplication, and clarifying questions come before implementation rather than after mistakes.

+
+# License and Attribution Hygiene
+
+## Verify attribution before writing
+
+License boilerplate is reusable; attribution is not. When copying or templating
+`LICENSE` / `CITATION.cff`, always audit the destination project's authorship
+before writing:
+
+1. Inspect the destination's source headers / README / git remote.
+2. Replace any copied trailing `Copyright YYYY <Name>` line with the
+   destination project's actual copyright holder.
+3. If there is any ambiguity, ask the user. Do not guess or preserve a copied
+   name "just in case".
+
+```bash
+# BAD - copies parent attribution into a submodule
+cp LICENSE extern/tfnmodule/LICENSE
+
+# GOOD - copy boilerplate only, then rewrite the trailing copyright line
+# after checking the destination project's own files.
+```
+
+## When asked to write CITATION.cff
+
+- Use author names from the destination project's source headers, README, or
+  existing citation metadata.
+- Do not add institutions, affiliations, addresses, or co-authors unless the
+  user asks or the project already declares them.
+- Do not infer ownership from adjacent repositories or old copied license text.
+
+## Submodules are not parent-repo files
+
+Submodule checkouts (`extern/<name>/`, `github-actions/`) are independent git
+repos. Files added there are working-tree changes inside the submodule, not
+normal parent-repo files. When editing a submodule, surface the two-step commit
+flow:
+
+```bash
+cd extern/<sub> && git add ... && git commit && git push
+cd ../..        && git add extern/<sub> && git commit  # bump pointer
+```
+
+The parent will show the submodule as dirty until both steps complete.

+globs: pyproject.toml,python/**,test/conftest.py,test/python/**

+---
+
+# ovrpy Python Package Conventions
+
+## Skipping is opt-in, never automatic
+
+`pytest test/python/` runs every parametrized variant by default - including
+the `[optix7]` (`gpu`) ones. A failing variant on a host lacking the hardware is
+a real signal, not an automatic skip.
+
+The user opts out explicitly:
+
+```bash
+pytest -m "not gpu"   # CPU-only
+pytest -m "not cpu"   # GPU-only
+ctest -LE gpu          # ctest equivalent
+```
+
+Do not add `libcuda.so.1` probing or any other "auto-skip the GPU tier on a
+GPU-less host" logic to the Python `_probe_backend`. The construct-time probe
+(`ovrpy.create_renderer(name)`) is the only acceptable automatic skip trigger,
+because it indicates a backend was not built / cannot construct, not that the
+host lacks runtime hardware.
+
+## pytest config lives in `pyproject.toml`
+
+Keep `[tool.pytest.ini_options]` in the repo-root `pyproject.toml`, not in
+`test/pytest.ini`. pytest finds the root config from any cwd in the tree; a
+`test/`-local config can be missed and cause `PytestUnknownMarkWarning` instead
+of `--strict-markers` enforcement.
+
+## Wheel install component is `ovrwheel`
+
+All `install(...)` rules that should ship in the pip/uv-built wheel must attach
+`COMPONENT ovrwheel`. `pyproject.toml` sets
+`install.components = ["ovrwheel"]` so third-party FetchContent install
+rules (glfw3, glad, ospray cmake configs) don't leak into the wheel.
+
+## Wheel binaries: bundle inside `<wheel>/ovrpy/` with `INSTALL_RPATH=$ORIGIN`
+
+`_core.so` plus the renderer/OSPRay/imgui closure live next to the package
+init. C++ apps go in `<wheel>/ovrpy/bin/` with `INSTALL_RPATH=$ORIGIN/..` and
+are surfaced on `$PATH` via Python entry-point shims in `python/ovrpy/_apps.py`
+(`os.execv` the bundled binary).
+
+Anchor shim lookups on `Path(_core.__file__).parent`, not
+`Path(__file__).parent`: editable installs resolve `_apps.py` to the source
+tree, while `_core.__file__` points at the real install location.
+
+## Loader-error helper translates missing system libs
+
+`python/ovrpy/__init__.py:_translate_loader_error` catches the dynamic linker's
+`lib<X>.so: cannot open shared object file` error and rewrites it with the
+missing system lib plus `apt`/`dnf` install hints. Extend `_SYSTEM_LIB_HINTS`
+when adding runtime deps that we deliberately don't bundle.

+## Top-level CMake options
+
+| Option | Default | Effect |
+| --- | --- | --- |
+| `OVR_BUILD_DEVICE_OPTIX7` | ON | OptiX 7 backend (requires CUDA + OptiX SDK) |
+| `OVR_BUILD_DEVICE_OSPRAY` | ON | OSPRay backend |
+| `OVR_BUILD_CUDA` | ON | Compile CUDA sources / link cudart |
+| `OVR_BUILD_OPENGL` | ON | GLFW + ImGui-based `renderapp`; also gates the imgui hooks compiled into the device backends |
+| `OVR_BUILD_APPS` | ON | Application executables (`renderapp`, `renderbatch`) |
+| `OVR_BUILD_PYTHON_BINDINGS` | OFF | The `ovrpy` pybind11 module |
+| `OVR_BUILD_USD` | OFF | USDA scene loading via Pixar USD |
+| `OVR_BUILD_TINYEXR` | ON | Fetch tinyexr v1.0.8 via FetchContent and link it into `rendercommon` to enable EXR read/write in `common/imageio.cpp`. Turn OFF to drop tinyexr from the build (a `.exr` filename then raises a runtime error) |
+| `OVR_BUILD_TINYOBJ` | OFF | Same, for tinyobjloader v1.0.6 → `tinyobj` INTERFACE target |
+| `OVR_BUILD_TINYGLTF` | OFF | Fetch tinygltf v2.5.0 via FetchContent and expose it as the `tinygltf` INTERFACE target (no consumer wired in by default) |
+| `OVR_BUILD_TESTS` | OFF | C++/CUDA unit tests + register Python tests |
+| `OVR_ENABLE_COVERAGE` | OFF | `--coverage -O0 -g` for GCC/Clang; adds the `coverage` target |
+
+## Manual cmake invocation
+
+The full equivalent of `./scripts/build.sh --all`:
+
+```bash
+cmake -S . -B build \
+  -DCMAKE_BUILD_TYPE=Release \
+  -DOVR_BUILD_DEVICE_OPTIX7=ON \
+  -DOVR_BUILD_DEVICE_OSPRAY=ON \
+  -DOVR_BUILD_PYTHON_BINDINGS=ON \
+  -DOVR_BUILD_TESTS=ON
+cmake --build build -j
+ctest --test-dir build --output-on-failure
+```
+
+Pointing at out-of-tree dependencies:
+
+```bash
+cmake -S . -B build \
+  -DOptiX_INSTALL_DIR=<path-to-optix7-sdk> \
+  -Dospray_DIR=<path-to-ospray>/lib/cmake/ospray-x.x.0 \
+  -DTBB_DIR=<path-to-tbb>/lib/cmake/tbb \
+  -DCMAKE_PREFIX_PATH=<path-to-libtorch>     # optional
+```
+
+## `scripts/build.sh` phase matrix
+
+`--configure`, `--build`, `--test` are additive; with no flags the script
+does configure + build. `--all` ≡ `--configure --build --test`. `--python`
+is orthogonal and toggles `OVR_BUILD_PYTHON_BINDINGS=ON`.
+
+| Invocation | Configure | Build | Test | `OVR_BUILD_PYTHON_BINDINGS` | `OVR_BUILD_TESTS` |
+| --- | :-: | :-: | :-: | :-: | :-: |
+| (none) | yes | yes |  | OFF | OFF |
+| `--configure` | yes |  |  | OFF | OFF |
+| `--build` |  | yes |  | (cache) | (cache) |
+| `--test` |  |  | yes | **ON** | **ON** |
+| `--build --test` |  | yes | yes | **ON** | **ON** |
+| `--configure --test` | yes |  | yes | **ON** | **ON** |
+| `--configure --build` | yes | yes |  | OFF | OFF |
+| `--configure --build --test` | yes | yes | yes | **ON** | **ON** |
+| `--all` | yes | yes | yes | **ON** | **ON** |
+| `--python` | yes | yes |  | **ON** | OFF |
+| `--build --python` |  | yes |  | **ON** (cache) | (cache) |
+| `--clean` | (deletes the build dir, then exits) | | | | |
+
+`--test` (and therefore `--all`) implies `--python` because the test tier
+is gated on the bindings. `--python` only takes effect when configure
+runs; if you only `--build`, the script reuses whatever was in the cmake
+cache from the previous configure.
+
+The script never mutates your environment. If `pytest` isn't importable
+when `--test` is requested it prints `pip install -e .[test]` and exits.
+If git submodules are missing it prints
+`git submodule update --init --recursive` and exits. It does **not** run
+pip, install system packages, or fetch submodules silently.
+
+Environment overrides:
+
+| Variable | Effect |
+| --- | --- |
+| `BUILD_DIR` | Override the build directory (default: `<repo>/build`) |
+| `CMAKE_ARGS` | Extra flags appended to the cmake invocation |
+| `CTEST_ARGS` | Extra flags passed to ctest (default: `-LE gpu --output-on-failure --no-tests=error`) |
+
+## Python wheel build (scikit-build-core)
+
+`pyproject.toml` drives
+[scikit-build-core](https://scikit-build-core.readthedocs.io/), so
+`pip install` / `uv sync` invokes the same top-level `CMakeLists.txt`
+the cmake-only flow uses, with these scoped defaults:
+
+```toml
+[tool.scikit-build.cmake.define]
+OVR_BUILD_PYTHON_BINDINGS = "ON"
+OVR_BUILD_APPS            = "OFF"
+OVR_BUILD_TESTS           = "OFF"
+```
+
+`OVR_BUILD_OPENGL` keeps its global default (`ON`) so the interactive
+viewer remains reachable from Python; the imgui/glad shared libs end up
+in the wheel alongside the renderer + OSPRay closure.
+

+```
+
+The C++ apps live in `bin/` rather than directly in the package root so
+their `INSTALL_RPATH=$ORIGIN/..` resolves the renderer + OSPRay closure
+without colliding with the wheel's pure-Python layout. They're surfaced
+on the user's `$PATH` via `[project.scripts]` entries in `pyproject.toml`
+that point at thin shims in `python/ovrpy/_apps.py`; each shim
+`os.execv`s the matching bundled binary, side-stepping the
+Python-version-specific RPATH path that would otherwise be needed to
+ship them in `<env>/bin/` directly.
+
+### Component scoping
+
+A custom CMake install component, `ovrwheel`, scopes which `install()`
+rules ship in the wheel — only the OVR-owned libs above. Third-party
+FetchContent install rules (glfw3, glad's own rules, OSPRay's cmake
+configs) would otherwise leak their files into the wheel; we filter them
+out via:
+
+```toml
+[tool.scikit-build]
+install.components = ["ovrwheel"]
+```
+
+The matching `python/CMakeLists.txt` rules attach `COMPONENT ovrwheel` to
+every `install(TARGETS ...)` and `install(DIRECTORY ...)` call, plus set
+`INSTALL_RPATH=$ORIGIN` on `_core`, `renderlib`, `rendercommon`, `imgui`,
+and `glad`. OSPRay's own libs already ship with
+`RUNPATH=$ORIGIN:$ORIGIN/../lib` so they self-resolve once unpacked.
+
+The OSPRay closure is sourced from `${ospray_DIR}/../..` (i.e. the lib
+dir under whatever prefix `ospray_DIR` points at — set either by the
+local FetchContent of `ospray_binary` or by an external
+`-Dospray_DIR=...` override).
+
+### Loader-error translation
+
+`python/ovrpy/__init__.py` wraps `from . import _core` and translates the
+dynamic linker's `lib<X>.so: cannot open shared object file` message
+into a friendlier `ImportError` that names the missing lib *and* prints
+the matching `apt`/`dnf` install command. Recognised system libs:
+
+| Lib | Used by | Ubuntu/Debian | RHEL/Fedora |
+| --- | --- | --- | --- |
+| `libcuda.so.1` | OptiX backend | (NVIDIA driver) | (NVIDIA driver) |
+| `libGL.so.1` | OpenGL tier | `libgl1` | `mesa-libGL` |
+| `libOpenGL.so.0` | OpenGL ABI (GLVND) | `libopengl0` | `libglvnd-opengl` |
+| `libX11.so.6` | imgui (interactive viewer) | `libx11-6` | `libX11` |
+| `libvulkan.so.1` | imgui (Vulkan loader) | `libvulkan1` | `vulkan-loader` |
+
+To extend, edit `_SYSTEM_LIB_HINTS` in `python/ovrpy/__init__.py`.
+
+### Headless / CPU-only opt-outs
+
+```bash
+pip install . -C cmake.define.OVR_BUILD_CUDA=OFF \
+              -C cmake.define.OVR_BUILD_DEVICE_OPTIX7=OFF
+# uv equivalent (pass through to scikit-build-core):
+CMAKE_ARGS="-DOVR_BUILD_CUDA=OFF -DOVR_BUILD_DEVICE_OPTIX7=OFF" uv sync --extra test
+```
+
+### Starting clean
+
+When something goes sideways (stale editable install, mismatched RPATHs,
+half-built `_core.so`):
+
+```bash
+rm -rf .venv build build/skbuild
+uv sync --extra test
+```
+
+`build/` holds the cmake-only artifacts (`scripts/build.sh`),
+`build/skbuild/` holds the scikit-build-core wheel-build tree; both are
+safe to delete.
+
+### Open follow-ups
+
+- Manylinux-tag adjustment (`auditwheel repair`) for cross-distro wheels.
+
+## Embedding OVR in a parent CMake project
+
+OVR uses `OVR_INSTALL_INCLUDEDIR` to describe the include root that gets
+encoded into installed/exported OVR interface targets:
+
+- Standalone OVR: the top-level `CMakeLists.txt` includes
+  `GNUInstallDirs` and defaults `OVR_INSTALL_INCLUDEDIR` to
+  `${CMAKE_INSTALL_INCLUDEDIR}` (normally `include`).
+- Embedded as a subdirectory: the parent may override
+  `OVR_INSTALL_INCLUDEDIR` before `add_subdirectory(...)` if OVR's
+  public headers should live under a package-specific subtree such as
+  `include/<package>`.
+- This variable controls only the *installed/exported* include
+  interface. OVR's build interface stays rooted in the OVR source tree
+  so the repository doesn't depend on parent-specific path conventions.
+
+Example:
+
+```cmake
+include(GNUInstallDirs)
+set(OVR_INSTALL_INCLUDEDIR "${CMAKE_INSTALL_INCLUDEDIR}/instantvnr")
+add_subdirectory(open-volume-renderer)
+```
+
+## Continuous integration
+
+`.github/workflows/main.yml` runs three jobs per push / PR:
+
+| Job | Runner | What it covers |
+| --- | --- | --- |
+| `build-linux` | ubuntu-22.04 + ubuntu-24.04 (matrix) | Release build with CUDA 11.8 / 12.8 × OSPRay fetchcontent / external; runs C++ + Python tests, **excluding `gpu`-labelled tests** because GHA runners have no NVIDIA GPU |
+| `build-windows` | windows-latest | Release build with MSVC + CUDA 12.8.1; runs C++ tests excluding `gpu` |
+| `coverage-linux` | ubuntu-22.04 | Debug build with `OVR_ENABLE_COVERAGE=ON`; produces `coverage.xml` (Cobertura) and an HTML drill-down via `gcovr`, uploaded as an artifact |
+
+No runner has a GPU, so the OptiX 7 backend's runtime tests are local-only.
+CI exercises the C++/binding surface and the OSPRay backend end-to-end.
+
+## Roadmap / open items
+
+- Commit golden-image regression baselines for the OSPRay and OptiX
+  backends (see `tests/README.md` and the `--update-baselines` workflow).
+- Per-setter render-side assertions in `tests/python/test_setters.py`
+  (currently binding-level smoke only).
+- A self-hosted GPU CI matrix entry to exercise the OptiX 7 + CUDA tests
+  that are skipped on GHA runners.
+- USD/USDA loader is functional but off by default; tests cover only the
+  JSON path today.
+- Manylinux wheel (`auditwheel repair`) for cross-distro distribution.

 ![Expected Rendering Result](./data/example.jpg)
 
-## TODO List
+OVR is a CUDA + OSPRay volume rendering framework. It ships:
+
+- A C++/CUDA library (`renderlib`) with two pluggable backends:
+  - **OptiX 7** (NVIDIA GPU) for hardware-accelerated ray tracing
+  - **OSPRay** (Intel CPU) for high-quality CPU rendering, including
+    distributed rendering hooks
+- Two reference applications:
+  - `renderapp` — interactive GLFW + ImGui viewer
+  - `renderbatch` — offline render-to-PNG driver
+- A Python package (`ovrpy`) built with pybind11, including the
+  `ovrpy-render` console script
+- A unified test suite (CTest + doctest + pytest) with optional
+  PSNR/SSIM rendering regression
+
+For build-system internals, packaging, CI, and contributor notes see
+[`DEV.md`](DEV.md). Test infrastructure (markers, golden-image workflow,
+coverage) is documented in [`tests/README.md`](tests/README.md).
+

-## Building the Code
+## Requirements
 
-This code contains two versions because the rendering framework was heavily factored and reimplemented 
-for multiple times. The new version lies in the `src` directory with the old version in `sources`. The 
-old version probably should not be used, so it is commented out intentionally. The old version is still
-being kept because there are functionalities yet to be ported.
+- CMake **>= 3.18**
+- A C++17 compiler — tested on GCC 11/13 (Ubuntu 22.04/24.04) and MSVC 2019/2022
+- Threads (POSIX or Win32)
 
-This code also contains experimental programs implemented for testing. Each directory in the `experiment`
-folder contains one standalone program. They are simplied versions of the main renderer, which can be 
-useful for embeded rendering implementation.
+Optional, gated by build-time flags (defaults shown):

-    - on Linux, tested with Ubuntu 18 and Ubuntu 19 default gcc installs.
-- CUDA 11.3 or above
-    - Download from developer.nvidia.com.
-    - on Linux, suggest to put `/usr/local/cuda/bin` into your `PATH`.
-- latest NVIDIA developer driver that comes with the SDK.
-    - download from http://developer.nvidia.com/optix and click "Get OptiX".

-    - download from http://developer.nvidia.com/optix and click "Get OptiX".
-    - on linux, suggest to set the environment variable `OptiX_INSTALL_DIR` to wherever you installed the SDK.  
-    `export OptiX_INSTALL_DIR=<wherever you installed OptiX 7.0 SDK>`
-    - on windows, the installer should automatically put it into the right directory/
-- OSPRay & TBB
-  - if you are building this code in `Release` mode, simply download the latest OSPRay 
-    from https://github.com/ospray/ospray/releases and TBB from https://github.com/oneapi-src/oneTBB/releases.
-  - if you are building this code in other configuration, you need to compile and install OSPRay manually. 
-    You also do not need to download TBB separately because OSPRay's superbuild will provide a version of TBB. 
+Submodules:
 
-Detailed steps below:
+```bash
+git submodule update --init --recursive
+```
 
-## Building
+`scripts/build.sh` checks `git submodule status` and refuses to proceed
+if any submodule is uninitialised — it never runs `git submodule update`
+on your behalf.
 
-- Install required packages
+## Install
 
-    - on Debian/Ubuntu: `sudo apt install libglfw3-dev cmake-curses-gui`
+There are two equivalent paths; pick whichever matches what you're after.
+Don't combine them on the same checkout — you'd build twice.
 
-- Clone the code
+### Python tier (`ovrpy`) via pip / uv
 
-- Create (and enter) a build directory
-```
-    mkdir build
-    cd build
-```
+```bash
+# uv
+uv sync --extra test
+uv run ovrpy-render --help
+uv run python -c "import ovrpy; print(ovrpy.vec2i())"
 
-- Configure with cmake (Debug Mode)
-    - Ubuntu: 
-    ```
-    cmake .. -DCMAKE_BUILD_TYPE=Debug 
-    # cmake .. \
-    #     -DCMAKE_BUILD_TYPE=Debug \
-    #     -DCMAKE_PREFIX_PATH=<path-to-libtorch> \

-    ```
-
-- And build
+# or plain pip
+pip install -e .[test]

 ```
-    cmake --build .
+
+`pip install` / `uv sync` invokes the same top-level `CMakeLists.txt`
+through [scikit-build-core](https://scikit-build-core.readthedocs.io/),
+producing a self-contained wheel at `<site-packages>/ovrpy/` (renderer +
+OSPRay closure + interactive OpenGL tier all bundled). Headless / CPU-only
+users can opt out of CUDA/OptiX:

-## Installing and Embedding
-
-OVR uses a generic CMake variable, `OVR_INSTALL_INCLUDEDIR`, to describe the
-include root that should be encoded into installed/exported OVR interface
-targets.
-
-- When OVR is configured standalone, `base/CMakeLists.txt` includes
-  `GNUInstallDirs` and defaults `OVR_INSTALL_INCLUDEDIR` to
-  `${CMAKE_INSTALL_INCLUDEDIR}` (normally `include`).
-- When OVR is embedded as a subdirectory of a parent project, the parent may
-  override `OVR_INSTALL_INCLUDEDIR` before `add_subdirectory(base)` if OVR's
-  public headers should live under a package-specific subtree such as
-  `include/instantvnr`.
-- This variable only controls the installed/exported include interface. OVR's
-  build interface intentionally stays rooted in the OVR source tree so the base
-  repository does not depend on parent-specific path conventions.
-
-Example parent-project override:
-
-```cmake
-include(GNUInstallDirs)
-set(OVR_INSTALL_INCLUDEDIR "${CMAKE_INSTALL_INCLUDEDIR}/instantvnr")
-add_subdirectory(base)
+ovrpy bundles its own renderer + OSPRay/imgui closure but relies on a few
+host-provided system libraries (`libcuda.so.1`, `libGL.so.1`,
+`libOpenGL.so.0`, `libX11.so.6`, `libvulkan.so.1`). If any are missing,
+`import ovrpy` raises a translated `ImportError` that names the missing
+lib and prints the exact `apt`/`dnf` install command. See
+[`DEV.md`](DEV.md#loader-error-translation) for the full table.
+
+### C++ apps via `scripts/build.sh`
+
+`--configure`, `--build`, `--test` are additive; `--all` ≡ all three.
+`--python` toggles the Python bindings on the cmake side (independent of
+the pip/uv flow above).
+
+```bash
+./scripts/build.sh                # configure + build (C++ only)
+./scripts/build.sh --python       # configure + build, with the ovrpy bindings
+./scripts/build.sh --all          # configure + build + test
+./scripts/build.sh --test         # tests only, against an existing build
+./scripts/build.sh --clean        # rm -rf the build dir, exit
 ```
 
-Use plain `${CMAKE_INSTALL_INCLUDEDIR}` when you want OVR headers installed
-directly under the global include root, and override `OVR_INSTALL_INCLUDEDIR`
-only when the parent package intentionally nests them under its own prefix.
+The full phase/option matrix and manual `cmake ... && cmake --build ...`
+recipes are in [`DEV.md`](DEV.md).
 
 ## Running
 
-- On Linux:
+After `pip install -e .` / `uv sync`, three console scripts land on
+`$PATH` — `ovrpy-render` is a Python entry point; `renderapp` and
+`renderbatch` are the bundled C++ apps wrapped by tiny entry-point
+shims (`python/ovrpy/_apps.py`) so they resolve their RPATH cleanly.
+
+```bash
+# Python entry point
+ovrpy-render data/configs/<scene>.json -o render.png --backend ospray
+
+# C++ apps (same binaries as the cmake-only flow, but on $PATH)
+renderapp   data/configs/<scene>.json    # interactive viewer (needs GLFW + display)
+renderbatch data/configs/<scene>.json    # offline render to PNG
+
+# Same C++ apps from a cmake-only build (no pip install needed)
+./build/renderapp   data/configs/<scene>.json
+./build/renderbatch data/configs/<scene>.json
 ```
-TODO
+
+Scene JSON files live under `data/configs/`; see
+`data/configs/README.md` for the schema. The Python tier exposes the
+same renderer through `import ovrpy`; see `tests/python/` for end-to-end
+usage examples.
+
+## Testing
+
+```bash
+./scripts/build.sh --all     # configure + build + run the full suite
+./scripts/build.sh --test    # iterate on tests against an existing build
+
+# pytest only (after `pip install -e .[test]` or `uv sync --extra test`):
+uv run pytest tests/python/ -v
 ```
+
+When `OVR_BUILD_TESTS=ON`, CMake hard-requires `Python3` +
+`OVR_BUILD_PYTHON_BINDINGS=ON` + an importable `pytest` and emits a
+`FATAL_ERROR` with the install command if anything is missing — there is
+no silent skip.
+
+See [`tests/README.md`](tests/README.md) for labels (`cpp` / `gpu` /
+`python` / `golden`), the golden-image baseline workflow, coverage, and
+troubleshooting.

-@brief the JSON type enumeration
-
-This enumeration collects the different JSON types. It is internally used to
-distinguish the stored values, and the functions @ref basic_json::is_null(),
-@ref basic_json::is_object(), @ref basic_json::is_array(),
-@ref basic_json::is_string(), @ref basic_json::is_boolean(),
-@ref basic_json::is_number() (with @ref basic_json::is_number_integer(),
-@ref basic_json::is_number_unsigned(), and @ref basic_json::is_number_float()),
-@ref basic_json::is_discarded(), @ref basic_json::is_primitive(), and
-@ref basic_json::is_structured() rely on it.
-
-@note There are three enumeration entries (number_integer, number_unsigned, and
-number_float), because the library distinguishes these three types for numbers:
-@ref basic_json::number_unsigned_t is used for unsigned integers,
-@ref basic_json::number_integer_t is used for signed integers, and
-@ref basic_json::number_float_t is used for floating-point numbers or to
-approximate integers which do not fit in the limits of their respective type.
-
-@sa see @ref basic_json::basic_json(const value_t value_type) -- create a JSON
-value with the default value for a given type
-
-@since version 1.0.0

-@brief comparison operator for JSON types
-
-Returns an ordering that is similar to Python:
-- order: null < boolean < number < object < array < string < binary
-- furthermore, each type is not smaller than itself
-- discarded values are not comparable
-- binary is represented as a b"" string in python and directly comparable to a
-  string; however, making a binary array directly comparable with a string would
-  be surprising behavior in a JSON file.

-@brief general exception of the @ref basic_json class
-
-This class is an extension of `std::exception` objects with a member @a id for
-exception ids. It is used as the base class for all exceptions thrown by the
-@ref basic_json class. This class can hence be used as "wildcard" to catch
-exceptions.
-
-Subclasses:
-- @ref parse_error for exceptions indicating a parse error
-- @ref invalid_iterator for exceptions indicating errors with iterators
-- @ref type_error for exceptions indicating executing a member function with
-                  a wrong type
-- @ref out_of_range for exceptions indicating access out of the defined range
-- @ref other_error for exceptions indicating other library errors
-
-@internal
-@note To have nothrow-copy-constructible exceptions, we internally use

-@brief exception indicating a parse error
-
-This exception is thrown by the library when a parse error occurs. Parse errors
-can occur during the deserialization of JSON text, CBOR, MessagePack, as well
-as when using JSON Patch.
-
-Member @a byte holds the byte index of the last read character in the input
-file.
-
-Exceptions have ids 1xx.

------------------------------- | --------------- | -------------------------
-json.exception.parse_error.101 | parse error at 2: unexpected end of input; expected string literal | This error indicates a syntax error while deserializing a JSON text. The error message describes that an unexpected token (character) was encountered, and the member @a byte indicates the error position.
-json.exception.parse_error.102 | parse error at 14: missing or wrong low surrogate | JSON uses the `\uxxxx` format to describe Unicode characters. Code points above above 0xFFFF are split into two `\uxxxx` entries ("surrogate pairs"). This error indicates that the surrogate pair is incomplete or contains an invalid code point.
-json.exception.parse_error.103 | parse error: code points above 0x10FFFF are invalid | Unicode supports code points up to 0x10FFFF. Code points above 0x10FFFF are invalid.
-json.exception.parse_error.104 | parse error: JSON patch must be an array of objects | [RFC 6902](https://tools.ietf.org/html/rfc6902) requires a JSON Patch document to be a JSON document that represents an array of objects.
-json.exception.parse_error.105 | parse error: operation must have string member 'op' | An operation of a JSON Patch document must contain exactly one "op" member, whose value indicates the operation to perform. Its value must be one of "add", "remove", "replace", "move", "copy", or "test"; other values are errors.
-json.exception.parse_error.106 | parse error: array index '01' must not begin with '0' | An array index in a JSON Pointer ([RFC 6901](https://tools.ietf.org/html/rfc6901)) may be `0` or any number without a leading `0`.
-json.exception.parse_error.107 | parse error: JSON pointer must be empty or begin with '/' - was: 'foo' | A JSON Pointer must be a Unicode string containing a sequence of zero or more reference tokens, each prefixed by a `/` character.
-json.exception.parse_error.108 | parse error: escape character '~' must be followed with '0' or '1' | In a JSON Pointer, only `~0` and `~1` are valid escape sequences.
-json.exception.parse_error.109 | parse error: array index 'one' is not a number | A JSON Pointer array index must be a number.
-json.exception.parse_error.110 | parse error at 1: cannot read 2 bytes from vector | When parsing CBOR or MessagePack, the byte vector ends before the complete value has been read.
-json.exception.parse_error.112 | parse error at 1: error reading CBOR; last byte: 0xF8 | Not all types of CBOR or MessagePack are supported. This exception occurs if an unsupported byte was read.
-json.exception.parse_error.113 | parse error at 2: expected a CBOR string; last byte: 0x98 | While parsing a map key, a value that is not a string has been read.
-json.exception.parse_error.114 | parse error: Unsupported BSON record type 0x0F | The parsing of the corresponding BSON record type is not implemented (yet).
-json.exception.parse_error.115 | parse error at byte 5: syntax error while parsing UBJSON high-precision number: invalid number text: 1A | A UBJSON high-precision number could not be parsed.
-
-@note For an input with n bytes, 1 is the index of the first character and n+1
-      is the index of the terminating null byte or the end of file. This also

-json.exception.invalid_iterator.202 | iterator does not fit current value | In an erase or insert function, the passed iterator @a pos does not belong to the JSON value for which the function was called. It hence does not define a valid position for the deletion/insertion.
-json.exception.invalid_iterator.203 | iterators do not fit current value | Either iterator passed to function @ref erase(IteratorType first, IteratorType last) does not belong to the JSON value from which values shall be erased. It hence does not define a valid range to delete values from.
-json.exception.invalid_iterator.204 | iterators out of range | When an iterator range for a primitive type (number, boolean, or string) is passed to a constructor or an erase function, this range has to be exactly (@ref begin(), @ref end()), because this is the only way the single stored value is expressed. All other ranges are invalid.
-json.exception.invalid_iterator.205 | iterator out of range | When an iterator for a primitive type (number, boolean, or string) is passed to an erase function, the iterator has to be the @ref begin() iterator, because it is the only way to address the stored value. All other iterators are invalid.
-json.exception.invalid_iterator.206 | cannot construct with iterators from null | The iterators passed to constructor @ref basic_json(InputIT first, InputIT last) belong to a JSON null value and hence to not define a valid range.
-json.exception.invalid_iterator.207 | cannot use key() for non-object iterators | The key() member function can only be used on iterators belonging to a JSON object, because other types do not have a concept of a key.
-json.exception.invalid_iterator.208 | cannot use operator[] for object iterators | The operator[] to specify a concrete offset cannot be used on iterators belonging to a JSON object, because JSON objects are unordered.
-json.exception.invalid_iterator.209 | cannot use offsets with object iterators | The offset operators (+, -, +=, -=) cannot be used on iterators belonging to a JSON object, because JSON objects are unordered.
-json.exception.invalid_iterator.210 | iterators do not fit | The iterator range passed to the insert function are not compatible, meaning they do not belong to the same container. Therefore, the range (@a first, @a last) is invalid.
-json.exception.invalid_iterator.211 | passed iterators may not belong to container | The iterator range passed to the insert function must not be a subrange of the container to insert to.
-json.exception.invalid_iterator.212 | cannot compare iterators of different containers | When two iterators are compared, they must belong to the same container.
-json.exception.invalid_iterator.213 | cannot compare order of object iterators | The order of object iterators cannot be compared, because JSON objects are unordered.
-json.exception.invalid_iterator.214 | cannot get value | Cannot get value for iterator: Either the iterator belongs to a null value or it is an iterator to a primitive type (number, boolean, or string), but the iterator is different to @ref begin().

-// of `integer_sequence<T, Ints...>` has a sequence of integers encoded in its

-    The state machine is realized with one label per state (prefixed with
-    "scan_number_") and `goto` statements between them. The state machine
-    contains cycles, but any cycle can be left when EOF is read. Therefore,
-    the function is guaranteed to terminate.
-
-    During scanning, the read bytes are stored in token_buffer. This string is
-    then converted to a signed integer, an unsigned integer, or a
-    floating-point number.
-
-    @return token_type::value_unsigned, token_type::value_integer, or
-            token_type::value_float if number could be successfully scanned,
-            token_type::parse_error otherwise
-
-    @note The scanner is independent of the current locale. Internally, the
-          locale's decimal point is used instead of `.` to work with the
-          locale-dependent converters.

-@brief a template for a bidirectional iterator for the @ref basic_json class
-This class implements a both iterators (iterator and const_iterator) for the
-@ref basic_json class.
-@note An iterator is called *initialized* when a pointer to a JSON value has
-      been set (e.g., by a constructor or a copy assignment). If the iterator is
-      default-constructed, it is *uninitialized* and most methods are undefined.
-      **The library uses assertions to detect calls on uninitialized iterators.**
-@requirement The class satisfies the following concept requirements:
--
-[BidirectionalIterator](https://en.cppreference.com/w/cpp/named_req/BidirectionalIterator):
-  The iterator that can be moved can be moved in both directions (i.e.
-  incremented and decremented).
-@since version 1.0.0, simplified in version 2.0.9, change to bidirectional

-@brief a template for a reverse iterator class
-
-@tparam Base the base iterator type to reverse. Valid types are @ref
-iterator (to create @ref reverse_iterator) and @ref const_iterator (to
-create @ref const_reverse_iterator).
-
-@requirement The class satisfies the following concept requirements:
--
-[BidirectionalIterator](https://en.cppreference.com/w/cpp/named_req/BidirectionalIterator):
-  The iterator that can be moved can be moved in both directions (i.e.
-  incremented and decremented).
-- [OutputIterator](https://en.cppreference.com/w/cpp/named_req/OutputIterator):
-  It is possible to write to the pointed-to element (only if @a Base is
-  @ref iterator).

-// The choice of (alpha,gamma) determines the size of the table and the form of

-//
-// The idea is to cut the number c * w = f * 2^e into two parts, which can be

-//
-//      f * 2^e = ( (f div 2^-e) * 2^-e + (f mod 2^-e) ) * 2^e

-//
-// The conversion of p1 into decimal form requires a series of divisions and
-// modulos by (a power of) 10. These operations are faster for 32-bit than for
-// 64-bit integers, so p1 should ideally fit into a 32-bit integer. This can be
-// achieved by choosing
-//
-//      -e >= 32   or   e <= -32 := gamma
-//
-// In order to convert the fractional part
-//
-//      p2 * 2^e = p2 / 2^-e = d[-1] / 10^1 + d[-2] / 10^2 + ...
-//
-// into decimal form, the fraction is repeatedly multiplied by 10 and the digits
-// d[-i] are extracted in order:
-//
-//      (10 * p2) div 2^-e = d[-1]
-//      (10 * p2) mod 2^-e = d[-2] / 10^1 + ...
-//
-// The multiplication by 10 must not overflow. It is sufficient to choose
-//
-//      10 * p2 < 16 * p2 = 2^4 * p2 <= 2^64.

-
-@requirement The class satisfies the following concept requirements:
-- Basic
- - [DefaultConstructible](https://en.cppreference.com/w/cpp/named_req/DefaultConstructible):
-   JSON values can be default constructed. The result will be a JSON null
-   value.
- - [MoveConstructible](https://en.cppreference.com/w/cpp/named_req/MoveConstructible):
-   A JSON value can be constructed from an rvalue argument.
- - [CopyConstructible](https://en.cppreference.com/w/cpp/named_req/CopyConstructible):
-   A JSON value can be copy-constructed from an lvalue expression.
- - [MoveAssignable](https://en.cppreference.com/w/cpp/named_req/MoveAssignable):
-   A JSON value van be assigned from an rvalue argument.
- - [CopyAssignable](https://en.cppreference.com/w/cpp/named_req/CopyAssignable):
-   A JSON value can be copy-assigned from an lvalue expression.
- - [Destructible](https://en.cppreference.com/w/cpp/named_req/Destructible):
-   JSON values can be destructed.
-- Layout
- - [StandardLayoutType](https://en.cppreference.com/w/cpp/named_req/StandardLayoutType):
-   JSON values have
-   [standard layout](https://en.cppreference.com/w/cpp/language/data_members#Standard_layout):
-   All non-static data members are private and standard layout types, the
-   class has no virtual functions or (virtual) base classes.
-- Library-wide
- - [EqualityComparable](https://en.cppreference.com/w/cpp/named_req/EqualityComparable):
-   JSON values can be compared with `==`, see @ref
-   operator==(const_reference,const_reference).
- - [LessThanComparable](https://en.cppreference.com/w/cpp/named_req/LessThanComparable):
-   JSON values can be compared with `<`, see @ref
-   operator<(const_reference,const_reference).
- - [Swappable](https://en.cppreference.com/w/cpp/named_req/Swappable):
-   Any JSON lvalue or rvalue of can be swapped with any lvalue or rvalue of
-   other compatible types, using unqualified function call @ref swap().
- - [NullablePointer](https://en.cppreference.com/w/cpp/named_req/NullablePointer):
-   JSON values can be compared against `std::nullptr_t` objects which are used
-   to model the `null` value.
-- Container
- - [Container](https://en.cppreference.com/w/cpp/named_req/Container):
-   JSON values can be used like STL containers and provide iterator access.
- - [ReversibleContainer](https://en.cppreference.com/w/cpp/named_req/ReversibleContainer);
-   JSON values can be used like STL containers and provide reverse iterator
-   access.
-
-@invariant The member variables @a m_value and @a m_type have the following
-relationship:
-- If `m_type == value_t::object`, then `m_value.object != nullptr`.
-- If `m_type == value_t::array`, then `m_value.array != nullptr`.
-- If `m_type == value_t::string`, then `m_value.string != nullptr`.
-The invariants are checked by member function assert_invariant().

-    @brief a type for an object
-
-    [RFC 8259](https://tools.ietf.org/html/rfc8259) describes JSON objects as follows:
-    > An object is an unordered collection of zero or more name/value pairs,
-    > where a name is a string and a value is a string, number, boolean, null,
-    > object, or array.
-
-    To store objects in C++, a type is defined by the template parameters
-    described below.
-
-    @tparam ObjectType  the container to store objects (e.g., `std::map` or
-    `std::unordered_map`)
-    @tparam StringType the type of the keys or names (e.g., `std::string`).
-    The comparison function `std::less<StringType>` is used to order elements
-    inside the container.
-    @tparam AllocatorType the allocator to use for objects (e.g.,
-    `std::allocator`)
-
-    #### Default type
-
-    With the default values for @a ObjectType (`std::map`), @a StringType
-    (`std::string`), and @a AllocatorType (`std::allocator`), the default
-    value for @a object_t is:
-
-    @code {.cpp}
-    std::map<
-      std::string, // key_type
-      basic_json, // value_type
-      std::less<std::string>, // key_compare
-      std::allocator<std::pair<const std::string, basic_json>> // allocator_type
-    >
-    @endcode
-
-    #### Behavior
-
-    The choice of @a object_t influences the behavior of the JSON class. With
-    the default type, objects have the following behavior:
-
-    - When all names are unique, objects will be interoperable in the sense
-      that all software implementations receiving that object will agree on
-      the name-value mappings.
-    - When the names within an object are not unique, it is unspecified which
-      one of the values for a given key will be chosen. For instance,
-      `{"key": 2, "key": 1}` could be equal to either `{"key": 1}` or
-      `{"key": 2}`.
-    - Internally, name/value pairs are stored in lexicographical order of the
-      names. Objects will also be serialized (see @ref dump) in this order.
-      For instance, `{"b": 1, "a": 2}` and `{"a": 2, "b": 1}` will be stored
-      and serialized as `{"a": 2, "b": 1}`.
-    - When comparing objects, the order of the name/value pairs is irrelevant.
-      This makes objects interoperable in the sense that they will not be
-      affected by these differences. For instance, `{"b": 1, "a": 2}` and
-      `{"a": 2, "b": 1}` will be treated as equal.
-
-    #### Limits
-
-    [RFC 8259](https://tools.ietf.org/html/rfc8259) specifies:
-    > An implementation may set limits on the maximum depth of nesting.
-
-    In this class, the object's limit of nesting is not explicitly constrained.
-    However, a maximum depth of nesting may be introduced by the compiler or
-    runtime environment. A theoretical limit can be queried by calling the
-    @ref max_size function of a JSON object.
-
-    #### Storage
-
-    Objects are stored as pointers in a @ref basic_json type. That is, for any
-    access to object values, a pointer of type `object_t*` must be
-    dereferenced.
-
-    @sa see @ref array_t -- type for an array value
-
-    @since version 1.0.0
-
-    @note The order name/value pairs are added to the object is *not*
-    preserved by the library. Therefore, iterating an object may return
-    name/value pairs in a different order than they were originally stored. In
-    fact, keys will be traversed in alphabetical order as `std::map` with
-    `std::less` is used by default. Please note this behavior conforms to [RFC
-    8259](https://tools.ietf.org/html/rfc8259), because any order implements the
-    specified "unordered" nature of JSON objects.

-    #### Encoding
-
-    Strings are stored in UTF-8 encoding. Therefore, functions like
-    `std::string::size()` or `std::string::length()` return the number of
-    bytes in the string rather than the number of characters or glyphs.
-
-    #### String comparison
-
-    [RFC 8259](https://tools.ietf.org/html/rfc8259) states:
-    > Software implementations are typically required to test names of object
-    > members for equality. Implementations that transform the textual
-    > representation into sequences of Unicode code units and then perform the
-    > comparison numerically, code unit by code unit, are interoperable in the

-    > inequality of two strings. For example, implementations that compare
-    > strings with escaped characters unconverted may incorrectly find that
-    > `"a\\b"` and `"a\u005Cb"` are not equal.
-
-    This implementation is interoperable as it does compare strings code unit
-    by code unit.

-    This description includes both integer and floating-point numbers.
-    However, C++ allows more precise storage if it is known whether the number

-      number. Internally, the value will be stored as decimal number. For
-      instance, the C++ integer literal `010` will be serialized to `8`.
-      During deserialization, leading zeros yield an error.
-    - Not-a-number (NaN) values will be serialized to `null`.

-
-    This implementation does exactly follow this approach, as it uses double
-    precision floating-point numbers. Note values smaller than
-    `-1.79769313486232e+308` and values greater than `1.79769313486232e+308`
-    will be stored as NaN internally and be serialized to `null`.
-
-    #### Storage
-
-    Floating-point number values are stored directly inside a @ref basic_json
-    type.
-
-    @sa see @ref number_integer_t -- type for number values (integer)
-
-    @sa see @ref number_unsigned_t -- type for number values (unsigned integer)

-    @brief a type for a packed binary type
-
-    This type is a type designed to carry binary data that appears in various
-    serialized formats, such as CBOR's Major Type 2, MessagePack's bin, and
-    BSON's generic binary subtype. This type is NOT a part of standard JSON and
-    exists solely for compatibility with these binary types. As such, it is
-    simply defined as an ordered sequence of zero or more byte values.
-
-    Additionally, as an implementation detail, the subtype of the binary data is
-    carried around as a `std::uint8_t`, which is compatible with both of the
-    binary data formats that use binary subtyping, (though the specific
-    numbering is incompatible with each other, and it is up to the user to
-    translate between them).
-
-    [CBOR's RFC 7049](https://tools.ietf.org/html/rfc7049) describes this type
-    as:
-    > Major type 2: a byte string. The string's length in bytes is represented
-    > following the rules for positive integers (major type 0).
-
-    [MessagePack's documentation on the bin type
-    family](https://github.com/msgpack/msgpack/blob/master/spec.md#bin-format-family)
-    describes this type as:
-    > Bin format family stores an byte array in 2, 3, or 5 bytes of extra bytes
-    > in addition to the size of the byte array.
-
-    [BSON's specifications](http://bsonspec.org/spec.html) describe several
-    binary types; however, this type is intended to represent the generic binary
-    type which has the description:
-    > Generic binary subtype - This is the most commonly used binary subtype and
-    > should be the 'default' for drivers and tools.
-
-    None of these impose any limitations on the internal representation other
-    than the basic unit of storage be some type of array whose parts are
-    decomposable into bytes.
-
-    The default representation of this binary format is a
-    `std::vector<std::uint8_t>`, which is a very common way to represent a byte
-    array in modern C++.
-
-    #### Default type
-
-    The default values for @a BinaryType is `std::vector<std::uint8_t>`
-
-    #### Storage
-
-    Binary Arrays are stored as pointers in a @ref basic_json type. That is,
-    for any access to array values, a pointer of the type `binary_t*` must be
-    dereferenced.
-
-    #### Notes on subtypes
-
-    - CBOR
-       - Binary values are represented as byte strings. Subtypes are serialized
-         as tagged values.
-    - MessagePack
-       - If a subtype is given and the binary array contains exactly 1, 2, 4, 8,
-         or 16 elements, the fixext family (fixext1, fixext2, fixext4, fixext8)
-         is used. For other sizes, the ext family (ext8, ext16, ext32) is used.
-         The subtype is then added as singed 8-bit integer.
-       - If no subtype is given, the bin family (bin8, bin16, bin32) is used.
-    - BSON
-       - If a subtype is given, it is used and added as unsigned 8-bit integer.
-       - If no subtype is given, the generic binary subtype 0x00 is used.

-    @brief per-element parser callback type
-
-    With a parser callback function, the result of parsing a JSON text can be
-    influenced. When passed to @ref parse, it is called on certain events
-    (passed as @ref parse_event_t via parameter @a event) with a set recursion
-    depth @a depth and context JSON value @a parsed. The return value of the
-    callback function is a boolean indicating whether the element that emitted
-    the callback shall be kept or not.
-
-    We distinguish six scenarios (determined by the event type) in which the
-    callback function can be called. The following table describes the values
-    of the parameters @a depth, @a event, and @a parsed.
-
-    parameter @a event | description | parameter @a depth | parameter @a parsed
-    ------------------ | ----------- | ------------------ | -------------------
-    parse_event_t::object_start | the parser read `{` and started to process a JSON object | depth of the parent of the JSON object | a JSON value with type discarded
-    parse_event_t::key | the parser read a key of a value in an object | depth of the currently parsed JSON object | a JSON string containing the key
-    parse_event_t::object_end | the parser read `}` and finished processing a JSON object | depth of the parent of the JSON object | the parsed JSON object
-    parse_event_t::array_start | the parser read `[` and started to process a JSON array | depth of the parent of the JSON array | a JSON value with type discarded
-    parse_event_t::array_end | the parser read `]` and finished processing a JSON array | depth of the parent of the JSON array | the parsed JSON array
-    parse_event_t::value | the parser finished reading a JSON value | depth of the value | the parsed JSON value
-
-    @image html callback_events.png "Example when certain parse events are triggered"
-
-    Discarding a value (i.e., returning `false`) has different effects
-    depending on the context in which function was called:
-
-    - Discarded values in structured types are skipped. That is, the parser
-      will behave as if the discarded value was never read.
-    - In case a value outside a structured type is skipped, it is replaced
-      with `null`. This case happens if the top-level element is skipped.
-
-    @param[in] depth  the depth of the recursion during parsing
-
-    @param[in] event  an event of type parse_event_t indicating the context in
-    the callback function has been called
-
-    @param[in,out] parsed  the current intermediate parse result; note that
-    writing to this value has no effect for parse_event_t::key events
-
-    @return Whether the JSON value which called the function during parsing
-    should be kept (`true`) or not (`false`). In the latter case, it is either
-    skipped completely or replaced by an empty discarded object.

-    @brief create a JSON value
-
-    This is a "catch all" constructor for all compatible JSON types; that is,

-    with `U = uncvref_t<CompatibleType>`, to be exact).
-
-    Template type @a CompatibleType includes, but is not limited to, the
-    following types:
-    - **arrays**: @ref array_t and all kinds of compatible containers such as
-      `std::vector`, `std::deque`, `std::list`, `std::forward_list`,
-      `std::array`, `std::valarray`, `std::set`, `std::unordered_set`,
-      `std::multiset`, and `std::unordered_multiset` with a `value_type` from
-      which a @ref basic_json value can be constructed.
-    - **objects**: @ref object_t and all kinds of compatible associative
-      containers such as `std::map`, `std::unordered_map`, `std::multimap`,
-      and `std::unordered_multimap` with a `key_type` compatible to
-      @ref string_t and a `value_type` from which a @ref basic_json value can
-      be constructed.
-    - **strings**: @ref string_t, string literals, and all compatible string
-      containers can be used.
-    - **numbers**: @ref number_integer_t, @ref number_unsigned_t,
-      @ref number_float_t, and all convertible number types such as `int`,
-      `size_t`, `int64_t`, `float` or `double` can be used.
-    - **boolean**: @ref boolean_t / `bool` can be used.
-    - **binary**: @ref binary_t / `std::vector<std::uint8_t>` may be used,
-      unfortunately because string literals cannot be distinguished from binary
-      character arrays by the C++ type system, all types compatible with `const
-      char*` will be directed to the string constructor instead.  This is both

-    - @a CompatibleType is not a @ref basic_json nested type (e.g.,

-    @brief create a container (array or object) from an initializer list
-
-    Creates a JSON value of type array or object from the passed initializer
-    list @a init. In case @a type_deduction is `true` (default), the type of
-    the JSON value to be created is deducted from the initializer list @a init
-    according to the following rules:
-
-    1. If the list is empty, an empty JSON object value `{}` is created.
-    2. If the list consists of pairs whose first element is a string, a JSON
-       object value is created where the first elements of the pairs are
-       treated as keys and the second elements are as values.
-    3. In all other cases, an array is created.
-
-    The rules aim to create the best fit between a C++ initializer list and
-    JSON values. The rationale is as follows:
-
-    1. The empty initializer list is written as `{}` which is exactly an empty
-       JSON object.
-    2. C++ has no way of describing mapped types other than to list a list of
-       pairs. As JSON requires that keys must be of type string, rule 2 is the
-       weakest constraint one can pose on initializer lists to interpret them
-       as an object.
-    3. In all other cases, the initializer list could not be interpreted as
-       JSON object type, so interpreting it as JSON array type is safe.
-
-    With the rules described above, the following JSON values cannot be
-    expressed by an initializer list:
-
-    - the empty array (`[]`): use @ref array(initializer_list_t)
-      with an empty initializer list in this case
-    - arrays whose elements satisfy rule 2: use @ref
-      array(initializer_list_t) with the same initializer list
-      in this case
-
-    @note When used without parentheses around an empty initializer list, @ref
-    basic_json() is called instead of this function, yielding the JSON null
-    value.
-
-    @param[in] init  initializer list with JSON values
-
-    @param[in] type_deduction internal parameter; when set to `true`, the type
-    of the JSON value is deducted from the initializer list @a init; when set
-    to `false`, the type provided via @a manual_type is forced. This mode is
-    used by the functions @ref array(initializer_list_t) and
-    @ref object(initializer_list_t).
-
-    @param[in] manual_type internal parameter; when @a type_deduction is set
-    to `false`, the created JSON value will use the provided type (only @ref
-    value_t::array and @ref value_t::object are valid); when @a type_deduction
-    is set to `true`, this parameter has no effect
-
-    @throw type_error.301 if @a type_deduction is `false`, @a manual_type is
-    `value_t::object`, but @a init contains an element which is not a pair
-    whose first element is a string. In this case, the constructor could not
-    create an object. If @a type_deduction would have be `true`, an array
-    would have been created. See @ref object(initializer_list_t)
-    for an example.
-
-    @complexity Linear in the size of the initializer list @a init.
-
-    @exceptionsafety Strong guarantee: if an exception is thrown, there are no
-    changes to any JSON value.

-    @brief serialization
-
-    Serialization function for JSON values. The function tries to mimic
-    Python's `json.dumps()` function, and currently supports its @a indent
-    and @a ensure_ascii parameters.
-
-    @param[in] indent If indent is nonnegative, then array elements and object
-    members will be pretty-printed with that indent level. An indent level of
-    `0` will only insert newlines. `-1` (the default) selects the most compact
-    representation.
-    @param[in] indent_char The character to use for indentation if @a indent is
-    greater than `0`. The default is ` ` (space).
-    @param[in] ensure_ascii If @a ensure_ascii is true, all non-ASCII characters
-    in the output are escaped with `\uXXXX` sequences, and the result consists
-    of ASCII characters only.
-    @param[in] error_handler  how to react on decoding errors; there are three
-    possible values: `strict` (throws and exception in case a decoding error
-    occurs; default), `replace` (replace invalid UTF-8 sequences with U+FFFD),
-    and `ignore` (ignore invalid UTF-8 sequences during serialization; all
-    bytes are copied to the output unchanged).
-
-    @return string containing the serialization of the JSON value
-
-    @throw type_error.316 if a string stored inside the JSON value is not
-                          UTF-8 encoded and @a error_handler is set to strict
-
-    @note Binary values are serialized as object containing two keys:
-      - "bytes": an array of bytes as integers
-      - "subtype": the subtype as integer or "null" if the binary has no subtype
-
-    @complexity Linear.
-
-    @exceptionsafety Strong guarantee: if an exception is thrown, there are no
-    changes in the JSON value.

-    @a indent_char\, and @a ensure_ascii parameters to the result of the

-    @brief comparison: equal
-
-    Compares two JSON values for equality according to the following rules:
-    - Two JSON values are equal if (1) they are from the same type and (2)
-      their stored values are the same according to their respective
-      `operator==`.
-    - Integer and floating-point numbers are automatically converted before
-      comparison. Note that two NaN values are always treated as unequal.
-    - Two JSON null values are equal.
-
-    @note Floating-point inside JSON values numbers are compared with
-    `json::number_float_t::operator==` which is `double::operator==` by
-    default. To compare floating-point while respecting an epsilon, an alternative
-    [comparison function](https://github.com/mariokonrad/marnav/blob/master/include/marnav/math/floatingpoint.hpp#L34-#L39)
-    could be used, for instance
-    @code {.cpp}
-    template<typename T, typename = typename std::enable_if<std::is_floating_point<T>::value, T>::type>
-    inline bool is_same(T a, T b, T epsilon = std::numeric_limits<T>::epsilon()) noexcept
-    {
-        return std::abs(a - b) <= epsilon;
-    }
-    @endcode
-    Or you can self-defined operator equal function like this:
-    @code {.cpp}
-    bool my_equal(const_reference lhs, const_reference rhs) {
-    const auto lhs_type lhs.type();
-    const auto rhs_type rhs.type();
-    if (lhs_type == rhs_type) {
-        switch(lhs_type)
-            // self_defined case
-            case value_t::number_float:
-                return std::abs(lhs - rhs) <= std::numeric_limits<float>::epsilon();
-            // other cases remain the same with the original
-            ...
-    }
-    ...
-    }
-    @endcode

-    @brief create a UBJSON serialization of a given JSON value
-
-    Serializes a given JSON value @a j to a byte vector using the UBJSON
-    (Universal Binary JSON) serialization format. UBJSON aims to be more compact
-    than JSON itself, yet more efficient to parse.
-
-    The library uses the following mapping from JSON values types to
-    UBJSON types according to the UBJSON specification:
-
-    JSON value type | value/range                       | UBJSON type | marker
-    --------------- | --------------------------------- | ----------- | ------
-    null            | `null`                            | null        | `Z`
-    boolean         | `true`                            | true        | `T`
-    boolean         | `false`                           | false       | `F`
-    number_integer  | -9223372036854775808..-2147483649 | int64       | `L`
-    number_integer  | -2147483648..-32769               | int32       | `l`
-    number_integer  | -32768..-129                      | int16       | `I`
-    number_integer  | -128..127                         | int8        | `i`
-    number_integer  | 128..255                          | uint8       | `U`
-    number_integer  | 256..32767                        | int16       | `I`
-    number_integer  | 32768..2147483647                 | int32       | `l`
-    number_integer  | 2147483648..9223372036854775807   | int64       | `L`
-    number_unsigned | 0..127                            | int8        | `i`
-    number_unsigned | 128..255                          | uint8       | `U`
-    number_unsigned | 256..32767                        | int16       | `I`
-    number_unsigned | 32768..2147483647                 | int32       | `l`
-    number_unsigned | 2147483648..9223372036854775807   | int64       | `L`
-    number_unsigned | 2147483649..18446744073709551615  | high-precision | `H`
-    number_float    | *any value*                       | float64     | `D`
-    string          | *with shortest length indicator*  | string      | `S`
-    array           | *see notes on optimized format*   | array       | `[`
-    object          | *see notes on optimized format*   | map         | `{`
-
-    @note The mapping is **complete** in the sense that any JSON value type
-          can be converted to a UBJSON value.
-
-    @note The following values can **not** be converted to a UBJSON value:
-          - strings with more than 9223372036854775807 bytes (theoretical)
-
-    @note The following markers are not used in the conversion:
-          - `Z`: no-op values are not created.
-          - `C`: single-byte strings are serialized with `S` markers.
-
-    @note Any UBJSON output created @ref to_ubjson can be successfully parsed
-          by @ref from_ubjson.
-
-    @note If NaN or Infinity are stored inside a JSON number, they are
-          serialized properly. This behavior differs from the @ref dump()
-          function which serializes NaN or Infinity to `null`.
-
-    @note The optimized formats for containers are supported: Parameter
-          @a use_size adds size information to the beginning of a container and
-          removes the closing marker. Parameter @a use_type further checks
-          whether all elements of a container have the same type and adds the
-          type marker to the beginning of the container. The @a use_type
-          parameter must only be used together with @a use_size = true. Note
-          that @a use_size = true alone may result in larger representations -
-          the benefit of this parameter is that the receiving side is
-          immediately informed on the number of elements of the container.
-
-    @note If the JSON data contains the binary type, the value stored is a list
-          of integers, as suggested by the UBJSON documentation.  In particular,
-          this means that serialization and the deserialization of a JSON
-          containing binary values into UBJSON and back will result in a
-          different JSON object.

-    @brief applies a JSON Merge Patch
-
-    The merge patch format is primarily intended for use with the HTTP PATCH
-    method as a means of describing a set of modifications to a target
-    resource's content. This function applies a merge patch to the current
-    JSON value.
-
-    The function implements the following algorithm from Section 2 of
-    [RFC 7396 (JSON Merge Patch)](https://tools.ietf.org/html/rfc7396):
-
-    ```
-    define MergePatch(Target, Patch):
-      if Patch is an Object:
-        if Target is not an Object:
-          Target = {} // Ignore the contents and set it to an empty Object
-        for each Name/Value pair in Patch:
-          if Value is null:
-            if Name exists in Target:
-              remove the Name/Value pair from Target
-          else:
-            Target[Name] = MergePatch(Target[Name], Value)
-        return Target
-      else:
-        return Patch
-    ```
-
-    Thereby, `Target` is the current object; that is, the patch is applied to
-    the current value.

-    The interface routines for reading and writing PLY polygon files.
-
-    Greg Turk, February 1994
-
-    ---------------------------------------------------------------
-
-    A PLY file contains a single polygonal _object_.
-
-    An object is composed of lists of _elements_.  Typical elements are
-    vertices, faces, edges and materials.
-
-    Each type of element for a given object has one or more _properties_
-    associated with the element type.  For instance, a vertex element may
-    have as properties the floating-point values x,y,z and the three unsigned
-    chars representing red, green and blue.

-Header for PLY polygon files.
-
-- Greg Turk, March 1994
-
-A PLY file contains a single polygonal _object_.
-
-An object is composed of lists of _elements_.  Typical elements are
-vertices, faces, edges and materials.
-
-Each type of element for a given object has one or more _properties_
-associated with the element type.  For instance, a vertex element may
-have as properties three floating-point values x,y,z and three unsigned
-chars for red, green and blue.

-   before you include this file in *one* C or C++ file to create the implementation.
-

-   #define STB_IMAGE_IMPLEMENTATION
-   #include "stb_image.h"
-
-   You can #define STBI_ASSERT(x) before the #include to avoid using assert.h.
-   And #define STBI_MALLOC, STBI_REALLOC, and STBI_FREE to avoid using malloc,realloc,free
-
-
-   QUICK NOTES:
-      Primarily of interest to game developers and other people who can
-          avoid problematic images and only need the trivial interface
-
-      JPEG baseline & progressive (12 bpc/arithmetic not supported, same as stock IJG lib)
-      PNG 1/2/4/8/16-bit-per-channel

-      HDR (radiance rgbE format)
-      PIC (Softimage PIC)
-      PNM (PPM and PGM binary only)

-// DOCUMENTATION
-//
-// Limitations:
-//    - no 12-bit-per-channel JPEG
-//    - no JPEGs with arithmetic coding
-//    - GIF always returns *comp=4
-//
-// Basic usage (see HDR discussion below for HDR usage):
-//    int x,y,n;
-//    unsigned char *data = stbi_load(filename, &x, &y, &n, 0);
-//    // ... process data if not NULL ...
-//    // ... x = width, y = height, n = # 8-bit components per pixel ...
-//    // ... replace '0' with '1'..'4' to force that many components per pixel
-//    // ... but 'n' will always be the number that it would have been if you said 0
-//    stbi_image_free(data)
-//
-// Standard parameters:
-//    int *x                 -- outputs image width in pixels
-//    int *y                 -- outputs image height in pixels
-//    int *channels_in_file  -- outputs # of image components in image file
-//    int desired_channels   -- if non-zero, # of image components requested in result
-//
-// The return value from an image loader is an 'unsigned char *' which points
-// to the pixel data, or NULL on an allocation failure or if the image is
-// corrupt or invalid. The pixel data consists of *y scanlines of *x pixels,
-// with each pixel consisting of N interleaved 8-bit components; the first
-// pixel pointed to is top-left-most in the image. There is no padding between
-// image scanlines or between pixels, regardless of format. The number of
-// components N is 'desired_channels' if desired_channels is non-zero, or
-// *channels_in_file otherwise. If desired_channels is non-zero,
-// *channels_in_file has the number of components that _would_ have been
-// output otherwise. E.g. if you set desired_channels to 4, you will always
-// get RGBA output, but you can check *channels_in_file to see if it's trivially
-// opaque because e.g. there were only 3 channels in the source image.
-//
-// An output image with N components has the following components interleaved
-// in this order in each pixel:
-//
-//     N=#comp     components
-//       1           grey
-//       2           grey, alpha
-//       3           red, green, blue
-//       4           red, green, blue, alpha
-//
-// If image loading fails for any reason, the return value will be NULL,
-// and *x, *y, *channels_in_file will be unchanged. The function
-// stbi_failure_reason() can be queried for an extremely brief, end-user
-// unfriendly explanation of why the load failed. Define STBI_NO_FAILURE_STRINGS
-// to avoid compiling these strings at all, and STBI_FAILURE_USERMSG to get slightly
-// more user-friendly ones.
-//
-// Paletted PNG, BMP, GIF, and PIC images are automatically depalettized.
-//
-// ===========================================================================
-//
-// UNICODE:
-//
-//   If compiling for Windows and you wish to use Unicode filenames, compile
-//   with
-//       #define STBI_WINDOWS_UTF8
-//   and pass utf8-encoded filenames. Call stbi_convert_wchar_to_utf8 to convert
-//   Windows wchar_t filenames to utf8.
-//
-// ===========================================================================
-//
-// Philosophy
-//
-// stb libraries are designed with the following priorities:
-//
-//    1. easy to use
-//    2. easy to maintain
-//    3. good performance
-//
-// Sometimes I let "good performance" creep up in priority over "easy to maintain",
-// and for best performance I may provide less-easy-to-use APIs that give higher
-// performance, in addition to the easy-to-use ones. Nevertheless, it's important
-// to keep in mind that from the standpoint of you, a client of this library,
-// all you care about is #1 and #3, and stb libraries DO NOT emphasize #3 above all.
-//
-// Some secondary priorities arise directly from the first two, some of which
-// provide more explicit reasons why performance can't be emphasized.
-//
-//    - Portable ("ease of use")
-//    - Small source code footprint ("easy to maintain")
-//    - No dependencies ("ease of use")
-//
-// ===========================================================================
-//
-// I/O callbacks
-//
-// I/O callbacks allow you to read from arbitrary sources, like packaged
-// files or some other source. Data read from callbacks are processed
-// through a small internal buffer (currently 128 bytes) to try to reduce
-// overhead.
-//
-// The three functions you must define are "read" (reads some bytes of data),
-// "skip" (skips some bytes of data), "eof" (reports if the stream is at the end).
-//
-// ===========================================================================
-//
-// SIMD support
-//
-// The JPEG decoder will try to automatically use SIMD kernels on x86 when
-// supported by the compiler. For ARM Neon support, you must explicitly
-// request it.
-//
-// (The old do-it-yourself SIMD API is no longer supported in the current
-// code.)
-//
-// On x86, SSE2 will automatically be used when available based on a run-time
-// test; if not, the generic C versions are used as a fall-back. On ARM targets,
-// the typical path is to have separate builds for NEON and non-NEON devices
-// (at least this is true for iOS and Android). Therefore, the NEON support is
-// toggled by a build flag: define STBI_NEON to get NEON loops.
-//
-// If for some reason you do not want to use any of SIMD code, or if
-// you have issues compiling it, you can disable it entirely by
-// defining STBI_NO_SIMD.
-//
-// ===========================================================================
-//
-// HDR image support   (disable by defining STBI_NO_HDR)
-//
-// stb_image supports loading HDR images in general, and currently the Radiance
-// .HDR file format specifically. You can still load any file through the existing
-// interface; if you attempt to load an HDR file, it will be automatically remapped
-// to LDR, assuming gamma 2.2 and an arbitrary scale factor defaulting to 1;
-// both of these constants can be reconfigured through this interface:
-//
-//     stbi_hdr_to_ldr_gamma(2.2f);
-//     stbi_hdr_to_ldr_scale(1.0f);
-//
-// (note, do not use _inverse_ constants; stbi_image will invert them
-// appropriately).
-//
-// Additionally, there is a new, parallel interface for loading files as
-// (linear) floats to preserve the full dynamic range:
-//
-//    float *data = stbi_loadf(filename, &x, &y, &n, 0);
-//
-// If you load LDR images through this interface, those images will
-// be promoted to floating point values, run through the inverse of
-// constants corresponding to the above:
-//
-//     stbi_ldr_to_hdr_scale(1.0f);
-//     stbi_ldr_to_hdr_gamma(2.2f);
-//
-// Finally, given a filename (or an open file or memory block--see header
-// file for details) containing image data, you can query for the "most
-// appropriate" interface to use (that is, whether the image is HDR or
-// not), using:
-//
-//     stbi_is_hdr(char *filename);
-//
-// ===========================================================================
-//
-// iPhone PNG support:
-//
-// By default we convert iphone-formatted PNGs back to RGB, even though
-// they are internally encoded differently. You can disable this conversion
-// by calling stbi_convert_iphone_png_to_rgb(0), in which case
-// you will always just get the native iphone "format" through (which
-// is BGR stored in RGB).
-//
-// Call stbi_set_unpremultiply_on_load(1) as well to force a divide per
-// pixel to remove any premultiplied alpha *only* if the image file explicitly
-// says there's premultiplied data (currently only happens in iPhone images,
-// and only if iPhone convert-to-rgb processing is on).
-//
-// ===========================================================================
-//
-// ADDITIONAL CONFIGURATION
-//
-//  - You can suppress implementation of any of the decoders to reduce
-//    your code footprint by #defining one or more of the following
-//    symbols before creating the implementation.
-//
-//        STBI_NO_JPEG
-//        STBI_NO_PNG
-//        STBI_NO_BMP
-//        STBI_NO_PSD
-//        STBI_NO_TGA
-//        STBI_NO_GIF
-//        STBI_NO_HDR
-//        STBI_NO_PIC
-//        STBI_NO_PNM   (.ppm and .pgm)
-//
-//  - You can request *only* certain decoders and suppress all other ones
-//    (this will be more forward-compatible, as addition of new decoders
-//    doesn't require you to disable them explicitly):
-//
-//        STBI_ONLY_JPEG
-//        STBI_ONLY_PNG
-//        STBI_ONLY_BMP
-//        STBI_ONLY_PSD
-//        STBI_ONLY_TGA
-//        STBI_ONLY_GIF
-//        STBI_ONLY_HDR
-//        STBI_ONLY_PIC
-//        STBI_ONLY_PNM   (.ppm and .pgm)
-//
-//   - If you use STBI_NO_PNG (or _ONLY_ without PNG), and you still
-//     want the zlib decoder to be available, #define STBI_SUPPORT_ZLIB

-/* stb_image_write - v1.14 - public domain - http://nothings.org/stb
-   writes out PNG/BMP/TGA/JPEG/HDR images to C stdio - Sean Barrett 2010-2015
-                                     no warranty implied; use at your own risk
-
-   Before #including,
-
-       #define STB_IMAGE_WRITE_IMPLEMENTATION
-
-   in the file that you want to have the implementation.
-
-   Will probably not work correctly with strict-aliasing optimizations.
-
-ABOUT:
-
-   This header file is a library for writing images to C stdio or a callback.
-
-   The PNG output is not optimal; it is 20-50% larger than the file
-   written by a decent optimizing implementation; though providing a custom
-   zlib compress function (see STBIW_ZLIB_COMPRESS) can mitigate that.
-   This library is designed for source code compactness and simplicity,
-   not optimal image file size or run-time performance.
-
-BUILDING:
-
-   You can #define STBIW_ASSERT(x) before the #include to avoid using assert.h.
-   You can #define STBIW_MALLOC(), STBIW_REALLOC(), and STBIW_FREE() to replace
-   malloc,realloc,free.
-   You can #define STBIW_MEMMOVE() to replace memmove()
-   You can #define STBIW_ZLIB_COMPRESS to use a custom zlib-style compress function
-   for PNG compression (instead of the builtin one), it must have the following signature:
-   unsigned char * my_compress(unsigned char *data, int data_len, int *out_len, int quality);
-   The returned data will be freed with STBIW_FREE() (free() by default),
-   so it must be heap allocated with STBIW_MALLOC() (malloc() by default),
-
-UNICODE:
-
-   If compiling for Windows and you wish to use Unicode filenames, compile
-   with
-       #define STBIW_WINDOWS_UTF8
-   and pass utf8-encoded filenames. Call stbiw_convert_wchar_to_utf8 to convert
-   Windows wchar_t filenames to utf8.
-
-USAGE:
-
-   There are five functions, one for each image file format:
-
-     int stbi_write_png(char const *filename, int w, int h, int comp, const void *data, int stride_in_bytes);
-     int stbi_write_bmp(char const *filename, int w, int h, int comp, const void *data);
-     int stbi_write_tga(char const *filename, int w, int h, int comp, const void *data);
-     int stbi_write_jpg(char const *filename, int w, int h, int comp, const void *data, int quality);
-     int stbi_write_hdr(char const *filename, int w, int h, int comp, const float *data);
-
-     void stbi_flip_vertically_on_write(int flag); // flag is non-zero to flip data vertically
-
-   There are also five equivalent functions that use an arbitrary write function. You are
-   expected to open/close your file-equivalent before and after calling these:
-
-     int stbi_write_png_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void  *data, int stride_in_bytes);
-     int stbi_write_bmp_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void  *data);
-     int stbi_write_tga_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void  *data);
-     int stbi_write_hdr_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const float *data);
-     int stbi_write_jpg_to_func(stbi_write_func *func, void *context, int x, int y, int comp, const void *data, int quality);
-
-   where the callback is:
-      void stbi_write_func(void *context, void *data, int size);
-
-   You can configure it with these global variables:
-      int stbi_write_tga_with_rle;             // defaults to true; set to 0 to disable RLE
-      int stbi_write_png_compression_level;    // defaults to 8; set to higher for more compression
-      int stbi_write_force_png_filter;         // defaults to -1; set to 0..5 to force a filter mode
-
-
-   You can define STBI_WRITE_NO_STDIO to disable the file variant of these
-   functions, so the library will not use stdio.h at all. However, this will
-   also disable HDR writing, because it requires stdio for formatted output.
-
-   Each function returns 0 on failure and non-0 on success.
-
-   The functions create an image file defined by the parameters. The image
-   is a rectangle of pixels stored from left-to-right, top-to-bottom.
-   Each pixel contains 'comp' channels of data stored interleaved with 8-bits
-   per channel, in the following order: 1=Y, 2=YA, 3=RGB, 4=RGBA. (Y is
-   monochrome color.) The rectangle is 'w' pixels wide and 'h' pixels tall.
-   The *data pointer points to the first byte of the top-left-most pixel.
-   For PNG, "stride_in_bytes" is the distance in bytes from the first byte of
-   a row of pixels to the first byte of the next row of pixels.
-
-   PNG creates output files with the same number of components as the input.
-   The BMP format expands Y to RGB in the file format and does not
-   output alpha.
-
-   PNG supports writing rectangles of data even when the bytes storing rows of
-   data are not consecutive in memory (e.g. sub-rectangles of a larger image),
-   by supplying the stride between the beginning of adjacent rows. The other
-   formats do not. (Thus you cannot write a native-format BMP through the BMP
-   writer, both because it is in BGR order and because it may have padding
-   at the end of the line.)
-
-   PNG allows you to set the deflate compression level by setting the global
-   variable 'stbi_write_png_compression_level' (it defaults to 8).
-
-   HDR expects linear float data. Since the format is always 32-bit rgb(e)
-   data, alpha (if provided) is discarded, and for monochrome data it is
-   replicated across all three channels.
-
-   TGA supports RLE or non-RLE compressed data. To use non-RLE-compressed
-   data, set the global variable 'stbi_write_tga_with_rle' to 0.
-
-   JPEG does ignore alpha channels in input data; quality is between 1 and 100.
-   Higher quality looks better but results in a bigger image.
-   JPEG baseline (no JPEG progressive).

-@brief the JSON type enumeration
-
-This enumeration collects the different JSON types. It is internally used to
-distinguish the stored values, and the functions @ref basic_json::is_null(),
-@ref basic_json::is_object(), @ref basic_json::is_array(),
-@ref basic_json::is_string(), @ref basic_json::is_boolean(),
-@ref basic_json::is_number() (with @ref basic_json::is_number_integer(),
-@ref basic_json::is_number_unsigned(), and @ref basic_json::is_number_float()),
-@ref basic_json::is_discarded(), @ref basic_json::is_primitive(), and
-@ref basic_json::is_structured() rely on it.
-
-@note There are three enumeration entries (number_integer, number_unsigned, and
-number_float), because the library distinguishes these three types for numbers:
-@ref basic_json::number_unsigned_t is used for unsigned integers,
-@ref basic_json::number_integer_t is used for signed integers, and
-@ref basic_json::number_float_t is used for floating-point numbers or to
-approximate integers which do not fit in the limits of their respective type.
-
-@sa see @ref basic_json::basic_json(const value_t value_type) -- create a JSON
-value with the default value for a given type
-
-@since version 1.0.0
-*/

-/*!
-@brief comparison operator for JSON types
-
-Returns an ordering that is similar to Python:
-- order: null < boolean < number < object < array < string < binary
-- furthermore, each type is not smaller than itself
-- discarded values are not comparable
-- binary is represented as a b"" string in python and directly comparable to a
-  string; however, making a binary array directly comparable with a string would
-  be surprising behavior in a JSON file.

-@brief exception indicating a parse error
-
-This exception is thrown by the library when a parse error occurs. Parse errors
-can occur during the deserialization of JSON text, CBOR, MessagePack, as well
-as when using JSON Patch.
-
-Member @a byte holds the byte index of the last read character in the input
-file.
-
-Exceptions have ids 1xx.

-name / id                      | example message | description
------------------------------- | --------------- | -------------------------
-json.exception.parse_error.101 | parse error at 2: unexpected end of input; expected string literal | This error indicates a syntax error while deserializing a JSON text. The error message describes that an unexpected token (character) was encountered, and the member @a byte indicates the error position.
-json.exception.parse_error.102 | parse error at 14: missing or wrong low surrogate | JSON uses the `\uxxxx` format to describe Unicode characters. Code points above above 0xFFFF are split into two `\uxxxx` entries ("surrogate pairs"). This error indicates that the surrogate pair is incomplete or contains an invalid code point.
-json.exception.parse_error.103 | parse error: code points above 0x10FFFF are invalid | Unicode supports code points up to 0x10FFFF. Code points above 0x10FFFF are invalid.
-json.exception.parse_error.104 | parse error: JSON patch must be an array of objects | [RFC 6902](https://tools.ietf.org/html/rfc6902) requires a JSON Patch document to be a JSON document that represents an array of objects.
-json.exception.parse_error.105 | parse error: operation must have string member 'op' | An operation of a JSON Patch document must contain exactly one "op" member, whose value indicates the operation to perform. Its value must be one of "add", "remove", "replace", "move", "copy", or "test"; other values are errors.
-json.exception.parse_error.106 | parse error: array index '01' must not begin with '0' | An array index in a JSON Pointer ([RFC 6901](https://tools.ietf.org/html/rfc6901)) may be `0` or any number without a leading `0`.
-json.exception.parse_error.107 | parse error: JSON pointer must be empty or begin with '/' - was: 'foo' | A JSON Pointer must be a Unicode string containing a sequence of zero or more reference tokens, each prefixed by a `/` character.
-json.exception.parse_error.108 | parse error: escape character '~' must be followed with '0' or '1' | In a JSON Pointer, only `~0` and `~1` are valid escape sequences.
-json.exception.parse_error.109 | parse error: array index 'one' is not a number | A JSON Pointer array index must be a number.
-json.exception.parse_error.110 | parse error at 1: cannot read 2 bytes from vector | When parsing CBOR or MessagePack, the byte vector ends before the complete value has been read.
-json.exception.parse_error.112 | parse error at 1: error reading CBOR; last byte: 0xF8 | Not all types of CBOR or MessagePack are supported. This exception occurs if an unsupported byte was read.
-json.exception.parse_error.113 | parse error at 2: expected a CBOR string; last byte: 0x98 | While parsing a map key, a value that is not a string has been read.
-json.exception.parse_error.114 | parse error: Unsupported BSON record type 0x0F | The parsing of the corresponding BSON record type is not implemented (yet).
-json.exception.parse_error.115 | parse error at byte 5: syntax error while parsing UBJSON high-precision number: invalid number text: 1A | A UBJSON high-precision number could not be parsed.
-
-@note For an input with n bytes, 1 is the index of the first character and n+1
-      is the index of the terminating null byte or the end of file. This also

-json.exception.invalid_iterator.202 | iterator does not fit current value | In an erase or insert function, the passed iterator @a pos does not belong to the JSON value for which the function was called. It hence does not define a valid position for the deletion/insertion.
-json.exception.invalid_iterator.203 | iterators do not fit current value | Either iterator passed to function @ref erase(IteratorType first, IteratorType last) does not belong to the JSON value from which values shall be erased. It hence does not define a valid range to delete values from.
-json.exception.invalid_iterator.204 | iterators out of range | When an iterator range for a primitive type (number, boolean, or string) is passed to a constructor or an erase function, this range has to be exactly (@ref begin(), @ref end()), because this is the only way the single stored value is expressed. All other ranges are invalid.
-json.exception.invalid_iterator.205 | iterator out of range | When an iterator for a primitive type (number, boolean, or string) is passed to an erase function, the iterator has to be the @ref begin() iterator, because it is the only way to address the stored value.

-json.exception.invalid_iterator.208 | cannot use operator[] for object iterators | The operator[] to specify a concrete offset cannot be used on iterators belonging to a JSON object, because JSON objects are unordered.
-json.exception.invalid_iterator.209 | cannot use offsets with object iterators | The offset operators (+, -, +=, -=) cannot be used on iterators belonging to a JSON object, because JSON objects are unordered.

-    @brief scan a number literal
-
-    This function scans a string according to Sect. 6 of RFC 8259.
-
-    The function is realized with a deterministic finite state machine derived
-    from the grammar described in RFC 8259. Starting in state "init", the
-    input is read and used to determined the next state. Only state "done"
-    accepts the number. State "error" is a trap state to model errors. In the
-    table below, "anything" means any character but the ones listed before.
-
-    state    | 0        | 1-9      | e E      | +       | -       | .        | anything

-    init     | zero     | any1     | [error]  | [error] | minus   | [error]  | [error]
-    minus    | zero     | any1     | [error]  | [error] | [error] | [error]  | [error]
-    zero     | done     | done     | exponent | done    | done    | decimal1 | done
-    any1     | any1     | any1     | exponent | done    | done    | decimal1 | done
-    decimal1 | decimal2 | decimal2 | [error]  | [error] | [error] | [error]  | [error]
-    decimal2 | decimal2 | decimal2 | exponent | done    | done    | done     | done

-    any2     | any2     | any2     | done     | done    | done    | done     | done
-
-    The state machine is realized with one label per state (prefixed with
-    "scan_number_") and `goto` statements between them. The state machine
-    contains cycles, but any cycle can be left when EOF is read. Therefore,
-    the function is guaranteed to terminate.
-
-    During scanning, the read bytes are stored in token_buffer. This string is
-    then converted to a signed integer, an unsigned integer, or a
-    floating-point number.
-
-    @return token_type::value_unsigned, token_type::value_integer, or
-            token_type::value_float if number could be successfully scanned,
-            token_type::parse_error otherwise
-
-    @note The scanner is independent of the current locale. Internally, the
-          locale's decimal point is used instead of `.` to work with the
-          locale-dependent converters.

-@brief a template for a bidirectional iterator for the @ref basic_json class
-This class implements a both iterators (iterator and const_iterator) for the
-@ref basic_json class.
-@note An iterator is called *initialized* when a pointer to a JSON value has
-      been set (e.g., by a constructor or a copy assignment). If the iterator is
-      default-constructed, it is *uninitialized* and most methods are undefined.
-      **The library uses assertions to detect calls on uninitialized iterators.**
-@requirement The class satisfies the following concept requirements:
--
-[BidirectionalIterator](https://en.cppreference.com/w/cpp/named_req/BidirectionalIterator):
-  The iterator that can be moved can be moved in both directions (i.e.
-  incremented and decremented).
-@since version 1.0.0, simplified in version 2.0.9, change to bidirectional
-       iterators in version 3.0.0 (see https://github.com/nlohmann/json/issues/593)

-@brief a template for a reverse iterator class
-
-@tparam Base the base iterator type to reverse. Valid types are @ref
-iterator (to create @ref reverse_iterator) and @ref const_iterator (to
-create @ref const_reverse_iterator).
-
-@requirement The class satisfies the following concept requirements:
--
-[BidirectionalIterator](https://en.cppreference.com/w/cpp/named_req/BidirectionalIterator):
-  The iterator that can be moved can be moved in both directions (i.e.
-  incremented and decremented).
-- [OutputIterator](https://en.cppreference.com/w/cpp/named_req/OutputIterator):
-  It is possible to write to the pointed-to element (only if @a Base is
-  @ref iterator).

-//
-// or

-// The choice of (alpha,gamma) determines the size of the table and the form of

-// The idea is to cut the number c * w = f * 2^e into two parts, which can be

-//
-//      f * 2^e = ( (f div 2^-e) * 2^-e + (f mod 2^-e) ) * 2^e

-// The conversion of p1 into decimal form requires a series of divisions and

-// achieved by choosing
-//
-//      -e >= 32   or   e <= -32 := gamma
-//
-// In order to convert the fractional part
-//
-//      p2 * 2^e = p2 / 2^-e = d[-1] / 10^1 + d[-2] / 10^2 + ...
-//
-// into decimal form, the fraction is repeatedly multiplied by 10 and the digits
-// d[-i] are extracted in order:
-//
-//      (10 * p2) div 2^-e = d[-1]
-//      (10 * p2) mod 2^-e = d[-2] / 10^1 + ...
-//
-// The multiplication by 10 must not overflow. It is sufficient to choose

-    @brief check whether a string is UTF-8 encoded
-
-    The function checks each byte of a string whether it is UTF-8 encoded. The
-    result of the check is stored in the @a state parameter. The function must
-    be called initially with state 0 (accept). State 1 means the string must
-    be rejected, because the current byte is not allowed. If the string is
-    completely processed, but the state is non-zero, the string ended
-    prematurely; that is, the last byte indicated more bytes should have
-    followed.
-
-    @param[in,out] state  the state of the decoding
-    @param[in,out] codep  codepoint (valid only if resulting state is UTF8_ACCEPT)
-    @param[in] byte       next byte to decode
-    @return               new state
-
-    @note The function has been edited: a std::array is used.

-
-@requirement The class satisfies the following concept requirements:
-- Basic
- - [DefaultConstructible](https://en.cppreference.com/w/cpp/named_req/DefaultConstructible):
-   JSON values can be default constructed. The result will be a JSON null
-   value.
- - [MoveConstructible](https://en.cppreference.com/w/cpp/named_req/MoveConstructible):
-   A JSON value can be constructed from an rvalue argument.
- - [CopyConstructible](https://en.cppreference.com/w/cpp/named_req/CopyConstructible):
-   A JSON value can be copy-constructed from an lvalue expression.
- - [MoveAssignable](https://en.cppreference.com/w/cpp/named_req/MoveAssignable):
-   A JSON value van be assigned from an rvalue argument.
- - [CopyAssignable](https://en.cppreference.com/w/cpp/named_req/CopyAssignable):
-   A JSON value can be copy-assigned from an lvalue expression.
- - [Destructible](https://en.cppreference.com/w/cpp/named_req/Destructible):
-   JSON values can be destructed.
-- Layout
- - [StandardLayoutType](https://en.cppreference.com/w/cpp/named_req/StandardLayoutType):
-   JSON values have
-   [standard layout](https://en.cppreference.com/w/cpp/language/data_members#Standard_layout):
-   All non-static data members are private and standard layout types, the
-   class has no virtual functions or (virtual) base classes.
-- Library-wide
- - [EqualityComparable](https://en.cppreference.com/w/cpp/named_req/EqualityComparable):
-   JSON values can be compared with `==`, see @ref
-   operator==(const_reference,const_reference).
- - [LessThanComparable](https://en.cppreference.com/w/cpp/named_req/LessThanComparable):
-   JSON values can be compared with `<`, see @ref
-   operator<(const_reference,const_reference).
- - [Swappable](https://en.cppreference.com/w/cpp/named_req/Swappable):
-   Any JSON lvalue or rvalue of can be swapped with any lvalue or rvalue of
-   other compatible types, using unqualified function call @ref swap().
- - [NullablePointer](https://en.cppreference.com/w/cpp/named_req/NullablePointer):
-   JSON values can be compared against `std::nullptr_t` objects which are used
-   to model the `null` value.
-- Container
- - [Container](https://en.cppreference.com/w/cpp/named_req/Container):
-   JSON values can be used like STL containers and provide iterator access.
- - [ReversibleContainer](https://en.cppreference.com/w/cpp/named_req/ReversibleContainer);
-   JSON values can be used like STL containers and provide reverse iterator
-   access.
-
-@invariant The member variables @a m_value and @a m_type have the following
-relationship:
-- If `m_type == value_t::object`, then `m_value.object != nullptr`.
-- If `m_type == value_t::array`, then `m_value.array != nullptr`.
-- If `m_type == value_t::string`, then `m_value.string != nullptr`.
-The invariants are checked by member function assert_invariant().

-    /*!
-    @brief a type for an object
-
-    [RFC 8259](https://tools.ietf.org/html/rfc8259) describes JSON objects as follows:
-    > An object is an unordered collection of zero or more name/value pairs,
-    > where a name is a string and a value is a string, number, boolean, null,
-    > object, or array.
-
-    To store objects in C++, a type is defined by the template parameters
-    described below.
-
-    @tparam ObjectType  the container to store objects (e.g., `std::map` or
-    `std::unordered_map`)
-    @tparam StringType the type of the keys or names (e.g., `std::string`).
-    The comparison function `std::less<StringType>` is used to order elements
-    inside the container.
-    @tparam AllocatorType the allocator to use for objects (e.g.,
-    `std::allocator`)
-
-    #### Default type
-
-    With the default values for @a ObjectType (`std::map`), @a StringType
-    (`std::string`), and @a AllocatorType (`std::allocator`), the default
-    value for @a object_t is:
-
-    @code {.cpp}
-    std::map<
-      std::string, // key_type
-      basic_json, // value_type
-      std::less<std::string>, // key_compare
-      std::allocator<std::pair<const std::string, basic_json>> // allocator_type
-    >
-    @endcode
-
-    #### Behavior
-
-    The choice of @a object_t influences the behavior of the JSON class. With
-    the default type, objects have the following behavior:
-
-    - When all names are unique, objects will be interoperable in the sense
-      that all software implementations receiving that object will agree on
-      the name-value mappings.
-    - When the names within an object are not unique, it is unspecified which
-      one of the values for a given key will be chosen. For instance,
-      `{"key": 2, "key": 1}` could be equal to either `{"key": 1}` or
-      `{"key": 2}`.
-    - Internally, name/value pairs are stored in lexicographical order of the
-      names. Objects will also be serialized (see @ref dump) in this order.
-      For instance, `{"b": 1, "a": 2}` and `{"a": 2, "b": 1}` will be stored
-      and serialized as `{"a": 2, "b": 1}`.
-    - When comparing objects, the order of the name/value pairs is irrelevant.
-      This makes objects interoperable in the sense that they will not be
-      affected by these differences. For instance, `{"b": 1, "a": 2}` and
-      `{"a": 2, "b": 1}` will be treated as equal.
-
-    #### Limits
-
-    [RFC 8259](https://tools.ietf.org/html/rfc8259) specifies:
-    > An implementation may set limits on the maximum depth of nesting.
-
-    In this class, the object's limit of nesting is not explicitly constrained.
-    However, a maximum depth of nesting may be introduced by the compiler or
-    runtime environment. A theoretical limit can be queried by calling the
-    @ref max_size function of a JSON object.
-
-    #### Storage
-
-    Objects are stored as pointers in a @ref basic_json type. That is, for any
-    access to object values, a pointer of type `object_t*` must be
-    dereferenced.
-
-    @sa see @ref array_t -- type for an array value
-
-    @since version 1.0.0
-
-    @note The order name/value pairs are added to the object is *not*
-    preserved by the library. Therefore, iterating an object may return
-    name/value pairs in a different order than they were originally stored. In
-    fact, keys will be traversed in alphabetical order as `std::map` with
-    `std::less` is used by default. Please note this behavior conforms to [RFC
-    8259](https://tools.ietf.org/html/rfc8259), because any order implements the
-    specified "unordered" nature of JSON objects.

-

-    bytes in the string rather than the number of characters or glyphs.
-
-    #### String comparison
-
-    [RFC 8259](https://tools.ietf.org/html/rfc8259) states:
-    > Software implementations are typically required to test names of object

-
-    This implementation is interoperable as it does compare strings code unit

-    > exponent part. Leading zeros are not allowed. (...) Numeric values that
-    > cannot be represented in the grammar below (such as Infinity and NaN)
-    > are not permitted.
-
-    This description includes both integer and floating-point numbers.
-    However, C++ allows more precise storage if it is known whether the number
-    is a signed integer, an unsigned integer or a floating-point number.
-    Therefore, three different types, @ref number_integer_t, @ref
-    number_unsigned_t and @ref number_float_t are used.
-
-    To store integer numbers in C++, a type is defined by the template
-    parameter @a NumberIntegerType which chooses the type to use.
-
-    #### Default type
-
-    With the default values for @a NumberIntegerType (`int64_t`), the default
-    value for @a number_integer_t is:
-
-    @code {.cpp}
-    int64_t
-    @endcode
-
-    #### Default behavior
-
-    - The restrictions about leading zeros is not enforced in C++. Instead,
-      leading zeros in integer literals lead to an interpretation as octal
-      number. Internally, the value will be stored as decimal number. For
-      instance, the C++ integer literal `010` will be serialized to `8`.
-      During deserialization, leading zeros yield an error.
-    - Not-a-number (NaN) values will be serialized to `null`.
-
-    #### Limits
-
-    [RFC 8259](https://tools.ietf.org/html/rfc8259) specifies:
-    > An implementation may set limits on the range and precision of numbers.
-
-    When the default type is used, the maximal integer number that can be
-    stored is `9223372036854775807` (INT64_MAX) and the minimal integer number
-    that can be stored is `-9223372036854775808` (INT64_MIN). Integer numbers
-    that are out of range will yield over/underflow when used in a
-    constructor. During deserialization, too large or small integer numbers
-    will be automatically be stored as @ref number_unsigned_t or @ref
-    number_float_t.
-
-    [RFC 8259](https://tools.ietf.org/html/rfc8259) further states:
-    > Note that when such software is used, numbers that are integers and are
-    > in the range \f$[-2^{53}+1, 2^{53}-1]\f$ are interoperable in the sense
-    > that implementations will agree exactly on their numeric values.
-
-    As this range is a subrange of the exactly supported range [INT64_MIN,
-    INT64_MAX], this class's integer type is interoperable.
-
-    #### Storage

-      instance, the C++ integer literal `010` will be serialized to `8`.
-      During deserialization, leading zeros yield an error.
-    - Not-a-number (NaN) values will be serialized to `null`.
-
-    #### Limits
-
-    [RFC 8259](https://tools.ietf.org/html/rfc8259) specifies:
-    > An implementation may set limits on the range and precision of numbers.
-
-    When the default type is used, the maximal integer number that can be
-    stored is `18446744073709551615` (UINT64_MAX) and the minimal integer
-    number that can be stored is `0`. Integer numbers that are out of range
-    will yield over/underflow when used in a constructor. During
-    deserialization, too large or small integer numbers will be automatically
-    be stored as @ref number_integer_t or @ref number_float_t.
-
-    [RFC 8259](https://tools.ietf.org/html/rfc8259) further states:
-    > Note that when such software is used, numbers that are integers and are
-    > in the range \f$[-2^{53}+1, 2^{53}-1]\f$ are interoperable in the sense
-    > that implementations will agree exactly on their numeric values.
-
-    As this range is a subrange (when considered in conjunction with the
-    number_integer_t type) of the exactly supported range [0, UINT64_MAX],
-    this class's integer type is interoperable.
-
-    #### Storage
-
-    Integer number values are stored directly inside a @ref basic_json type.

-    @brief a type for a number (floating-point)
-
-    [RFC 8259](https://tools.ietf.org/html/rfc8259) describes numbers as follows:
-    > The representation of numbers is similar to that used in most
-    > programming languages. A number is represented in base 10 using decimal
-    > digits. It contains an integer component that may be prefixed with an
-    > optional minus sign, which may be followed by a fraction part and/or an
-    > exponent part. Leading zeros are not allowed. (...) Numeric values that
-    > cannot be represented in the grammar below (such as Infinity and NaN)
-    > are not permitted.
-
-    This description includes both integer and floating-point numbers.
-    However, C++ allows more precise storage if it is known whether the number
-    is a signed integer, an unsigned integer or a floating-point number.
-    Therefore, three different types, @ref number_integer_t, @ref
-    number_unsigned_t and @ref number_float_t are used.
-
-    To store floating-point numbers in C++, a type is defined by the template
-    parameter @a NumberFloatType which chooses the type to use.
-
-    #### Default type
-
-    With the default values for @a NumberFloatType (`double`), the default
-    value for @a number_float_t is:
-
-    @code {.cpp}
-    double
-    @endcode
-
-    #### Default behavior
-
-    - The restrictions about leading zeros is not enforced in C++. Instead,
-      leading zeros in floating-point literals will be ignored. Internally,
-      the value will be stored as decimal number. For instance, the C++
-      floating-point literal `01.2` will be serialized to `1.2`. During
-      deserialization, leading zeros yield an error.
-    - Not-a-number (NaN) values will be serialized to `null`.
-
-    #### Limits
-
-    [RFC 8259](https://tools.ietf.org/html/rfc8259) states:
-    > This specification allows implementations to set limits on the range and
-    > precision of numbers accepted. Since software that implements IEEE
-    > 754-2008 binary64 (double precision) numbers is generally available and
-    > widely used, good interoperability can be achieved by implementations
-    > that expect no more precision or range than these provide, in the sense
-    > that implementations will approximate JSON numbers within the expected
-    > precision.
-
-    This implementation does exactly follow this approach, as it uses double
-    precision floating-point numbers. Note values smaller than
-    `-1.79769313486232e+308` and values greater than `1.79769313486232e+308`
-    will be stored as NaN internally and be serialized to `null`.
-
-    #### Storage
-
-    Floating-point number values are stored directly inside a @ref basic_json
-    type.

-    /*!
-    @brief a type for a packed binary type
-
-    This type is a type designed to carry binary data that appears in various
-    serialized formats, such as CBOR's Major Type 2, MessagePack's bin, and
-    BSON's generic binary subtype. This type is NOT a part of standard JSON and
-    exists solely for compatibility with these binary types. As such, it is
-    simply defined as an ordered sequence of zero or more byte values.
-
-    Additionally, as an implementation detail, the subtype of the binary data is
-    carried around as a `std::uint8_t`, which is compatible with both of the
-    binary data formats that use binary subtyping, (though the specific
-    numbering is incompatible with each other, and it is up to the user to
-    translate between them).
-
-    [CBOR's RFC 7049](https://tools.ietf.org/html/rfc7049) describes this type
-    as:
-    > Major type 2: a byte string. The string's length in bytes is represented
-    > following the rules for positive integers (major type 0).
-
-    [MessagePack's documentation on the bin type
-    family](https://github.com/msgpack/msgpack/blob/master/spec.md#bin-format-family)
-    describes this type as:
-    > Bin format family stores an byte array in 2, 3, or 5 bytes of extra bytes
-    > in addition to the size of the byte array.
-
-    [BSON's specifications](http://bsonspec.org/spec.html) describe several
-    binary types; however, this type is intended to represent the generic binary
-    type which has the description:
-    > Generic binary subtype - This is the most commonly used binary subtype and
-    > should be the 'default' for drivers and tools.
-
-    None of these impose any limitations on the internal representation other
-    than the basic unit of storage be some type of array whose parts are
-    decomposable into bytes.
-
-    The default representation of this binary format is a
-    `std::vector<std::uint8_t>`, which is a very common way to represent a byte
-    array in modern C++.
-
-    #### Default type
-
-    The default values for @a BinaryType is `std::vector<std::uint8_t>`
-
-    #### Storage
-
-    Binary Arrays are stored as pointers in a @ref basic_json type. That is,
-    for any access to array values, a pointer of the type `binary_t*` must be
-    dereferenced.
-
-    #### Notes on subtypes
-
-    - CBOR
-       - Binary values are represented as byte strings. Subtypes are serialized
-         as tagged values.
-    - MessagePack
-       - If a subtype is given and the binary array contains exactly 1, 2, 4, 8,
-         or 16 elements, the fixext family (fixext1, fixext2, fixext4, fixext8)
-         is used. For other sizes, the ext family (ext8, ext16, ext32) is used.
-         The subtype is then added as singed 8-bit integer.
-       - If no subtype is given, the bin family (bin8, bin16, bin32) is used.
-    - BSON
-       - If a subtype is given, it is used and added as unsigned 8-bit integer.
-       - If no subtype is given, the generic binary subtype 0x00 is used.

-    @brief per-element parser callback type
-
-    With a parser callback function, the result of parsing a JSON text can be
-    influenced. When passed to @ref parse, it is called on certain events
-    (passed as @ref parse_event_t via parameter @a event) with a set recursion
-    depth @a depth and context JSON value @a parsed. The return value of the
-    callback function is a boolean indicating whether the element that emitted
-    the callback shall be kept or not.
-
-    We distinguish six scenarios (determined by the event type) in which the
-    callback function can be called. The following table describes the values
-    of the parameters @a depth, @a event, and @a parsed.
-
-    parameter @a event | description | parameter @a depth | parameter @a parsed
-    ------------------ | ----------- | ------------------ | -------------------
-    parse_event_t::object_start | the parser read `{` and started to process a JSON object | depth of the parent of the JSON object | a JSON value with type discarded
-    parse_event_t::key | the parser read a key of a value in an object | depth of the currently parsed JSON object | a JSON string containing the key
-    parse_event_t::object_end | the parser read `}` and finished processing a JSON object | depth of the parent of the JSON object | the parsed JSON object
-    parse_event_t::array_start | the parser read `[` and started to process a JSON array | depth of the parent of the JSON array | a JSON value with type discarded
-    parse_event_t::array_end | the parser read `]` and finished processing a JSON array | depth of the parent of the JSON array | the parsed JSON array
-    parse_event_t::value | the parser finished reading a JSON value | depth of the value | the parsed JSON value
-
-    @image html callback_events.png "Example when certain parse events are triggered"
-
-    Discarding a value (i.e., returning `false`) has different effects
-    depending on the context in which function was called:
-
-    - Discarded values in structured types are skipped. That is, the parser
-      will behave as if the discarded value was never read.
-    - In case a value outside a structured type is skipped, it is replaced
-      with `null`. This case happens if the top-level element is skipped.
-
-    @param[in] depth  the depth of the recursion during parsing
-
-    @param[in] event  an event of type parse_event_t indicating the context in
-    the callback function has been called
-
-    @param[in,out] parsed  the current intermediate parse result; note that
-    writing to this value has no effect for parse_event_t::key events
-
-    @return Whether the JSON value which called the function during parsing
-    should be kept (`true`) or not (`false`). In the latter case, it is either
-    skipped completely or replaced by an empty discarded object.

-    with `U = uncvref_t<CompatibleType>`, to be exact).
-
-    Template type @a CompatibleType includes, but is not limited to, the
-    following types:
-    - **arrays**: @ref array_t and all kinds of compatible containers such as
-      `std::vector`, `std::deque`, `std::list`, `std::forward_list`,
-      `std::array`, `std::valarray`, `std::set`, `std::unordered_set`,
-      `std::multiset`, and `std::unordered_multiset` with a `value_type` from
-      which a @ref basic_json value can be constructed.
-    - **objects**: @ref object_t and all kinds of compatible associative
-      containers such as `std::map`, `std::unordered_map`, `std::multimap`,
-      and `std::unordered_multimap` with a `key_type` compatible to
-      @ref string_t and a `value_type` from which a @ref basic_json value can
-      be constructed.
-    - **strings**: @ref string_t, string literals, and all compatible string
-      containers can be used.
-    - **numbers**: @ref number_integer_t, @ref number_unsigned_t,
-      @ref number_float_t, and all convertible number types such as `int`,
-      `size_t`, `int64_t`, `float` or `double` can be used.
-    - **boolean**: @ref boolean_t / `bool` can be used.
-    - **binary**: @ref binary_t / `std::vector<std::uint8_t>` may be used,
-      unfortunately because string literals cannot be distinguished from binary
-      character arrays by the C++ type system, all types compatible with `const
-      char*` will be directed to the string constructor instead.  This is both

-    @brief create a container (array or object) from an initializer list
-
-    Creates a JSON value of type array or object from the passed initializer
-    list @a init. In case @a type_deduction is `true` (default), the type of
-    the JSON value to be created is deducted from the initializer list @a init
-    according to the following rules:
-
-    1. If the list is empty, an empty JSON object value `{}` is created.
-    2. If the list consists of pairs whose first element is a string, a JSON
-       object value is created where the first elements of the pairs are
-       treated as keys and the second elements are as values.
-    3. In all other cases, an array is created.
-
-    The rules aim to create the best fit between a C++ initializer list and
-    JSON values. The rationale is as follows:
-
-    1. The empty initializer list is written as `{}` which is exactly an empty
-       JSON object.
-    2. C++ has no way of describing mapped types other than to list a list of
-       pairs. As JSON requires that keys must be of type string, rule 2 is the
-       weakest constraint one can pose on initializer lists to interpret them
-       as an object.
-    3. In all other cases, the initializer list could not be interpreted as
-       JSON object type, so interpreting it as JSON array type is safe.
-
-    With the rules described above, the following JSON values cannot be
-    expressed by an initializer list:
-
-    - the empty array (`[]`): use @ref array(initializer_list_t)
-      with an empty initializer list in this case
-    - arrays whose elements satisfy rule 2: use @ref
-      array(initializer_list_t) with the same initializer list
-      in this case
-
-    @note When used without parentheses around an empty initializer list, @ref
-    basic_json() is called instead of this function, yielding the JSON null
-    value.
-
-    @param[in] init  initializer list with JSON values
-
-    @param[in] type_deduction internal parameter; when set to `true`, the type
-    of the JSON value is deducted from the initializer list @a init; when set
-    to `false`, the type provided via @a manual_type is forced. This mode is
-    used by the functions @ref array(initializer_list_t) and
-    @ref object(initializer_list_t).
-
-    @param[in] manual_type internal parameter; when @a type_deduction is set
-    to `false`, the created JSON value will use the provided type (only @ref
-    value_t::array and @ref value_t::object are valid); when @a type_deduction
-    is set to `true`, this parameter has no effect
-
-    @throw type_error.301 if @a type_deduction is `false`, @a manual_type is
-    `value_t::object`, but @a init contains an element which is not a pair
-    whose first element is a string. In this case, the constructor could not
-    create an object. If @a type_deduction would have be `true`, an array
-    would have been created. See @ref object(initializer_list_t)
-    for an example.
-
-    @complexity Linear in the size of the initializer list @a init.

-

-    and @a ensure_ascii parameters.
-
-    @param[in] indent If indent is nonnegative, then array elements and object
-    members will be pretty-printed with that indent level. An indent level of
-    `0` will only insert newlines. `-1` (the default) selects the most compact
-    representation.
-    @param[in] indent_char The character to use for indentation if @a indent is
-    greater than `0`. The default is ` ` (space).
-    @param[in] ensure_ascii If @a ensure_ascii is true, all non-ASCII characters
-    in the output are escaped with `\uXXXX` sequences, and the result consists
-    of ASCII characters only.
-    @param[in] error_handler  how to react on decoding errors; there are three
-    possible values: `strict` (throws and exception in case a decoding error
-    occurs; default), `replace` (replace invalid UTF-8 sequences with U+FFFD),
-    and `ignore` (ignore invalid UTF-8 sequences during serialization; all
-    bytes are copied to the output unchanged).
-
-    @return string containing the serialization of the JSON value
-
-    @throw type_error.316 if a string stored inside the JSON value is not
-                          UTF-8 encoded and @a error_handler is set to strict
-
-    @note Binary values are serialized as object containing two keys:
-      - "bytes": an array of bytes as integers
-      - "subtype": the subtype as integer or "null" if the binary has no subtype
-
-    @complexity Linear.

-    @brief helper to access iterator member functions in range-based for
-
-    This function allows to access @ref iterator::key() and @ref
-    iterator::value() during range-based for loops. In these loops, a
-    reference to the JSON values is returned, so there is no access to the
-    underlying iterator.
-
-    For loop without `items()` function:
-
-    @code{cpp}
-    for (auto it = j_object.begin(); it != j_object.end(); ++it)
-    {
-        std::cout << "key: " << it.key() << ", value:" << it.value() << '\n';
-    }
-    @endcode
-
-    Range-based for loop without `items()` function:
-
-    @code{cpp}
-    for (auto it : j_object)
-    {
-        // "it" is of type json::reference and has no key() member
-        std::cout << "value: " << it << '\n';
-    }
-    @endcode
-
-    Range-based for loop with `items()` function:
-
-    @code{cpp}
-    for (auto& el : j_object.items())
-    {
-        std::cout << "key: " << el.key() << ", value:" << el.value() << '\n';
-    }
-    @endcode
-
-    The `items()` function also allows to use
-    [structured bindings](https://en.cppreference.com/w/cpp/language/structured_binding)
-    (C++17):
-
-    @code{cpp}
-    for (auto& [key, val] : j_object.items())
-    {
-        std::cout << "key: " << key << ", value:" << val << '\n';
-    }
-    @endcode
-
-    @note When iterating over an array, `key()` will return the index of the
-          element as string (see example). For primitive types (e.g., numbers),
-          `key()` returns an empty string.
-
-    @warning Using `items()` on temporary objects is dangerous. Make sure the
-             object's lifetime exeeds the iteration. See
-             <https://github.com/nlohmann/json/issues/2040> for more
-             information.

-    @brief comparison: equal
-
-    Compares two JSON values for equality according to the following rules:
-    - Two JSON values are equal if (1) they are from the same type and (2)
-      their stored values are the same according to their respective
-      `operator==`.
-    - Integer and floating-point numbers are automatically converted before
-      comparison. Note that two NaN values are always treated as unequal.
-    - Two JSON null values are equal.
-
-    @note Floating-point inside JSON values numbers are compared with
-    `json::number_float_t::operator==` which is `double::operator==` by
-    default. To compare floating-point while respecting an epsilon, an alternative
-    [comparison function](https://github.com/mariokonrad/marnav/blob/master/include/marnav/math/floatingpoint.hpp#L34-#L39)
-    could be used, for instance
-    @code {.cpp}
-    template<typename T, typename = typename std::enable_if<std::is_floating_point<T>::value, T>::type>
-    inline bool is_same(T a, T b, T epsilon = std::numeric_limits<T>::epsilon()) noexcept
-    {
-        return std::abs(a - b) <= epsilon;
-    }
-    @endcode
-    Or you can self-defined operator equal function like this:
-    @code {.cpp}
-    bool my_equal(const_reference lhs, const_reference rhs) {
-    const auto lhs_type lhs.type();
-    const auto rhs_type rhs.type();
-    if (lhs_type == rhs_type) {

-            case value_t::number_float:
-                return std::abs(lhs - rhs) <= std::numeric_limits<float>::epsilon();
-            // other cases remain the same with the original
-            ...
-    }
-    ...
-    }
-    @endcode
-

-
-    @note The optimized formats for containers are supported: Parameter
-          @a use_size adds size information to the beginning of a container and
-          removes the closing marker. Parameter @a use_type further checks
-          whether all elements of a container have the same type and adds the
-          type marker to the beginning of the container. The @a use_type
-          parameter must only be used together with @a use_size = true. Note
-          that @a use_size = true alone may result in larger representations -
-          the benefit of this parameter is that the receiving side is
-          immediately informed on the number of elements of the container.
-
-    @note If the JSON data contains the binary type, the value stored is a list
-          of integers, as suggested by the UBJSON documentation.  In particular,
-          this means that serialization and the deserialization of a JSON
-          containing binary values into UBJSON and back will result in a

-    @brief applies a JSON Merge Patch
-
-    The merge patch format is primarily intended for use with the HTTP PATCH
-    method as a means of describing a set of modifications to a target
-    resource's content. This function applies a merge patch to the current
-    JSON value.
-
-    The function implements the following algorithm from Section 2 of
-    [RFC 7396 (JSON Merge Patch)](https://tools.ietf.org/html/rfc7396):
-
-    ```
-    define MergePatch(Target, Patch):
-      if Patch is an Object:
-        if Target is not an Object:
-          Target = {} // Ignore the contents and set it to an empty Object
-        for each Name/Value pair in Patch:
-          if Value is null:
-            if Name exists in Target:
-              remove the Name/Value pair from Target
-          else:
-            Target[Name] = MergePatch(Target[Name], Value)
-        return Target
-      else:
-        return Patch
-    ```
-
-    Thereby, `Target` is the current object; that is, the patch is applied to
-    the current value.
-
-    @param[in] apply_patch  the patch to apply
-

-`tinyexr` is a small, single header-only library to load and save OpenEXR (.exr) images.
-`tinyexr` is written in portable C++ (no library dependency except for STL), thus `tinyexr` is good to embed into your application.
-To use `tinyexr`, simply copy `tinyexr.h`, `miniz.c` and `miniz.h`(for zlib. You can use system-installed zlib instead of miniz. Controlled with `TINYEXR_USE_MINIZ` compile flag) into your project.
-

-
-## Experimental
-
-* [experimental/js/](experimental/js) JavaScript port using Emscripten
-
-## Usage
-
-NOTE: **API is still subject to change**. See the source code for details.
-
-Include `tinyexr.h` with `TINYEXR_IMPLEMENTATION` flag (do this only for **one** .cc file).
-
-```cpp
-//Please include your own zlib-compatible API header before
-//including `tinyexr.h` when you disable `TINYEXR_USE_MINIZ`
-//#define TINYEXR_USE_MINIZ 0
-//#include "zlib.h"
-#define TINYEXR_IMPLEMENTATION
-#include "tinyexr.h"
-```
-
-### Compile flags
-
-* `TINYEXR_USE_MINIZ` Use miniz (default = 1). Please include `zlib.h` header before `tinyexr.h` if you disable miniz support(e.g. use system's zlib).
-* `TINYEXR_USE_PIZ` Enable PIZ compression support (default = 1)
-* `TINYEXR_USE_ZFP` Enable ZFP compression supoort (TinyEXR extension, default = 0)
-* `TINYEXR_USE_THREAD` Enable threaded loading using C++11 thread (Requires C++11 compiler, default = 0)
-* `TINYEXR_USE_OPENMP` Enable OpenMP threading support (default = 1 if `_OPENMP` is defined)
-  * Use `TINYEXR_USE_OPENMP=0` to force disable OpenMP code path even if OpenMP is available/enabled in the compiler.
-
-### Quickly reading RGB(A) EXR file.
-
-```cpp
-  const char* input = "asakusa.exr";
-  float* out; // width * height * RGBA
-  int width;
-  int height;
-  const char* err = NULL; // or nullptr in C++11
-
-  int ret = LoadEXR(&out, &width, &height, input, &err);
-
-  if (ret != TINYEXR_SUCCESS) {
-    if (err) {
-       fprintf(stderr, "ERR : %s\n", err);
-       FreeEXRErrorMessage(err); // release memory of error message.
-    }
-  } else {
-    ...
-    free(out); // release memory of image data
-  }
-
-```
-
-### Reading layered RGB(A) EXR file.
-
-If you want to read EXR image with layer info (channel has a name with delimiter `.`), please use `LoadEXRWithLayer` API.
-
-You need to know layer name in advance (e.g. through `EXRLayers` API).
-
-```cpp
-  const char* input = ...;
-  const char* layer_name = "diffuse"; // or use EXRLayers to get list of layer names in .exr
-  float* out; // width * height * RGBA
-  int width;
-  int height;
-  const char* err = NULL; // or nullptr in C++11
-
-  // will read `diffuse.R`, `diffuse.G`, `diffuse.B`, (`diffuse.A`) channels
-  int ret = LoadEXRWithLayer(&out, &width, &height, input, layer_name, &err);
-
-  if (ret != TINYEXR_SUCCESS) {
-    if (err) {
-       fprintf(stderr, "ERR : %s\n", err);
-       FreeEXRErrorMessage(err); // release memory of error message.
-    }
-  } else {
-    ...
-    free(out); // release memory of image data
-  }
-
-```
-
-### Loading Singlepart EXR from a file.
-
-Scanline and tiled format are supported.
-
-```cpp
-  // 1. Read EXR version.
-  EXRVersion exr_version;
-
-  int ret = ParseEXRVersionFromFile(&exr_version, argv[1]);
-  if (ret != 0) {
-    fprintf(stderr, "Invalid EXR file: %s\n", argv[1]);
-    return -1;
-  }
-
-  if (exr_version.multipart) {
-    // must be multipart flag is false.
-    return -1;
-  }
-
-  // 2. Read EXR header
-  EXRHeader exr_header;
-  InitEXRHeader(&exr_header);
-
-  const char* err = NULL; // or `nullptr` in C++11 or later.
-  ret = ParseEXRHeaderFromFile(&exr_header, &exr_version, argv[1], &err);
-  if (ret != 0) {
-    fprintf(stderr, "Parse EXR err: %s\n", err);
-    FreeEXRErrorMessage(err); // free's buffer for an error message
-    return ret;
-  }
-
-  // // Read HALF channel as FLOAT.
-  // for (int i = 0; i < exr_header.num_channels; i++) {
-  //   if (exr_header.pixel_types[i] == TINYEXR_PIXELTYPE_HALF) {
-  //     exr_header.requested_pixel_types[i] = TINYEXR_PIXELTYPE_FLOAT;
-  //   }
-  // }
-
-  EXRImage exr_image;
-  InitEXRImage(&exr_image);
-
-  ret = LoadEXRImageFromFile(&exr_image, &exr_header, argv[1], &err);
-  if (ret != 0) {
-    fprintf(stderr, "Load EXR err: %s\n", err);
-    FreeEXRHeader(&exr_header);
-    FreeEXRErrorMessage(err); // free's buffer for an error message
-    return ret;
-  }
-
-  // 3. Access image data
-  // `exr_image.images` will be filled when EXR is scanline format.
-  // `exr_image.tiled` will be filled when EXR is tiled format.
-
-  // 4. Free image data

-
-### deepview
-
-`examples/deepview` is simple deep image viewer in OpenGL.
-
-![DeepViewExample](https://github.com/syoyo/tinyexr/blob/master/examples/deepview/deepview_screencast.gif?raw=true)
-
-## TinyEXR extension
-
-### ZFP
-
-#### NOTE
-
-TinyEXR adds ZFP compression as an experimemtal support (Linux and MacOSX only).
-
-ZFP only supports FLOAT format pixel, and its image width and height must be the multiple of 4, since ZFP compresses pixels with 4x4 pixel block.
-
-#### Setup
-
-Checkout zfp repo as an submodule.
-
-    $ git submodule update --init
-
-#### Build
-
-Then build ZFP
-
-    $ cd deps/ZFP
-    $ mkdir -p lib   # Create `lib` directory if not exist
-    $ make
-
-Set `1` to `TINYEXT_USE_ZFP` define in `tinyexr.h`
-
-Build your app with linking `deps/ZFP/lib/libzfp.a`
-
-#### ZFP attribute
-
-For ZFP EXR image, the following attribute must exist in its EXR image.
-
-* `zfpCompressionType` (uchar).
-  * 0 = fixed rate compression
-  * 1 = precision based variable rate compression
-  * 2 = accuracy based variable rate compression
-
-And the one of following attributes must exist in EXR, depending on the `zfpCompressionType` value.
-
-* `zfpCompressionRate` (double)
-  * Specifies compression rate for fixed rate compression.
-* `zfpCompressionPrecision` (int32)
-  * Specifies the number of bits for precision based variable rate compression.
-* `zfpCompressionTolerance` (double)
-  * Specifies the tolerance value for accuracy based variable rate compression.
-
-#### Note on ZFP compression.
-
-At least ZFP code itself works well on big endian machine.

-## Miniz
-
-Miniz is a lossless, high performance data compression library in a single source file that implements the zlib (RFC 1950) and Deflate (RFC 1951) compressed data format specification standards. It supports the most commonly used functions exported by the zlib library, but is a completely independent implementation so zlib's licensing requirements do not apply. Miniz also contains simple to use functions for writing .PNG format image files and reading/writing/appending .ZIP format archives. Miniz's compression speed has been tuned to be comparable to zlib's, and it also has a specialized real-time compressor function designed to compare well against fastlz/minilzo.
-
-## Usage
-
-Please use the files from the [releases page](https://github.com/richgel999/miniz/releases) in your projects. Do not use the git checkout directly! The different source and header files are [amalgamated](https://www.sqlite.org/amalgamation.html) into one `miniz.c`/`miniz.h` pair in a build step (`amalgamate.sh`). Include `miniz.c` and `miniz.h` in your project to use Miniz.
-
-## Features
-
-* MIT licensed
-* A portable, single source and header file library written in plain C. Tested with GCC, clang and Visual Studio.
-* Easily tuned and trimmed down by defines
-* A drop-in replacement for zlib's most used API's (tested in several open source projects that use zlib, such as libpng and libzip).
-* Fills a single threaded performance vs. compression ratio gap between several popular real-time compressors and zlib. For example, at level 1, miniz.c compresses around 5-9% better than minilzo, but is approx. 35% slower. At levels 2-9, miniz.c is designed to compare favorably against zlib's ratio and speed. See the miniz performance comparison page for example timings.
-* Not a block based compressor: miniz.c fully supports stream based processing using a coroutine-style implementation. The zlib-style API functions can be called a single byte at a time if that's all you've got.
-* Easy to use. The low-level compressor (tdefl) and decompressor (tinfl) have simple state structs which can be saved/restored as needed with simple memcpy's. The low-level codec API's don't use the heap in any way.
-* Entire inflater (including optional zlib header parsing and Adler-32 checking) is implemented in a single function as a coroutine, which is separately available in a small (~550 line) source file: miniz_tinfl.c
-* A fairly complete (but totally optional) set of .ZIP archive manipulation and extraction API's. The archive functionality is intended to solve common problems encountered in embedded, mobile, or game development situations. (The archive API's are purposely just powerful enough to write an entire archiver given a bit of additional higher-level logic.)
-
-## Known Problems
-
-* No support for encrypted archives. Not sure how useful this stuff is in practice.
-* Minimal documentation. The assumption is that the user is already familiar with the basic zlib API. I need to write an API wiki - for now I've tried to place key comments before each enum/API, and I've included 6 examples that demonstrate how to use the module's major features.
-
-## Special Thanks
-
-Thanks to Alex Evans for the PNG writer function. Also, thanks to Paul Holden and Thorsten Scheuermann for feedback and testing, Matt Pritchard for all his encouragement, and Sean Barrett's various public domain libraries for inspiration (and encouraging me to write miniz.c in C, which was much more enjoyable and less painful than I thought it would be considering I've been programming in C++ for so long).
-
-Thanks to Bruce Dawson for reporting a problem with the level_and_flags archive API parameter (which is fixed in v1.12) and general feedback, and Janez Zemva for indirectly encouraging me into writing more examples.
-
-## Patents
-
-I was recently asked if miniz avoids patent issues. miniz purposely uses the same core algorithms as the ones used by zlib. The compressor uses vanilla hash chaining as described [here](https://datatracker.ietf.org/doc/html/rfc1951#section-4). Also see the [gzip FAQ](https://web.archive.org/web/20160308045258/http://www.gzip.org/#faq11). In my opinion, if miniz falls prey to a patent attack then zlib/gzip are likely to be at serious risk too.

-/* miniz.c 3.0.0 - public domain deflate/inflate, zlib-subset, ZIP reading/writing/appending, PNG writing
-   See "unlicense" statement at the end of this file.
-   Rich Geldreich <richgel99@gmail.com>, last updated Oct. 13, 2013
-   Implements RFC 1950: http://www.ietf.org/rfc/rfc1950.txt and RFC 1951: http://www.ietf.org/rfc/rfc1951.txt
-
-   Most API's defined in miniz.c are optional. For example, to disable the archive related functions just define
-   MINIZ_NO_ARCHIVE_APIS, or to get rid of all stdio usage define MINIZ_NO_STDIO (see the list below for more macros).
-
-   * Low-level Deflate/Inflate implementation notes:
-
-     Compression: Use the "tdefl" API's. The compressor supports raw, static, and dynamic blocks, lazy or
-     greedy parsing, match length filtering, RLE-only, and Huffman-only streams. It performs and compresses
-     approximately as well as zlib.
-
-     Decompression: Use the "tinfl" API's. The entire decompressor is implemented as a single function
-     coroutine: see tinfl_decompress(). It supports decompression into a 32KB (or larger power of 2) wrapping buffer, or into a memory
-     block large enough to hold the entire file.
-
-     The low-level tdefl/tinfl API's do not make any use of dynamic memory allocation.
-
-   * zlib-style API notes:
-
-     miniz.c implements a fairly large subset of zlib. There's enough functionality present for it to be a drop-in
-     zlib replacement in many apps:
-        The z_stream struct, optional memory allocation callbacks
-        deflateInit/deflateInit2/deflate/deflateReset/deflateEnd/deflateBound
-        inflateInit/inflateInit2/inflate/inflateReset/inflateEnd
-        compress, compress2, compressBound, uncompress
-        CRC-32, Adler-32 - Using modern, minimal code size, CPU cache friendly routines.
-        Supports raw deflate streams or standard zlib streams with adler-32 checking.
-
-     Limitations:
-      The callback API's are not implemented yet. No support for gzip headers or zlib static dictionaries.
-      I've tried to closely emulate zlib's various flavors of stream flushing and return status codes, but
-      there are no guarantees that miniz.c pulls this off perfectly.
-
-   * PNG writing: See the tdefl_write_image_to_png_file_in_memory() function, originally written by
-     Alex Evans. Supports 1-4 bytes/pixel images.
-
-   * ZIP archive API notes:
-
-     The ZIP archive API's where designed with simplicity and efficiency in mind, with just enough abstraction to
-     get the job done with minimal fuss. There are simple API's to retrieve file information, read files from
-     existing archives, create new archives, append new files to existing archives, or clone archive data from
-     one archive to another. It supports archives located in memory or the heap, on disk (using stdio.h),
-     or you can specify custom file read/write callbacks.
-
-     - Archive reading: Just call this function to read a single file from a disk archive:
-
-      void *mz_zip_extract_archive_file_to_heap(const char *pZip_filename, const char *pArchive_name,
-        size_t *pSize, mz_uint zip_flags);
-
-     For more complex cases, use the "mz_zip_reader" functions. Upon opening an archive, the entire central
-     directory is located and read as-is into memory, and subsequent file access only occurs when reading individual files.
-
-     - Archives file scanning: The simple way is to use this function to scan a loaded archive for a specific file:
-
-     int mz_zip_reader_locate_file(mz_zip_archive *pZip, const char *pName, const char *pComment, mz_uint flags);
-
-     The locate operation can optionally check file comments too, which (as one example) can be used to identify
-     multiple versions of the same file in an archive. This function uses a simple linear search through the central
-     directory, so it's not very fast.
-
-     Alternately, you can iterate through all the files in an archive (using mz_zip_reader_get_num_files()) and
-     retrieve detailed info on each file by calling mz_zip_reader_file_stat().
-
-     - Archive creation: Use the "mz_zip_writer" functions. The ZIP writer immediately writes compressed file data
-     to disk and builds an exact image of the central directory in memory. The central directory image is written
-     all at once at the end of the archive file when the archive is finalized.
-
-     The archive writer can optionally align each file's local header and file data to any power of 2 alignment,
-     which can be useful when the archive will be read from optical media. Also, the writer supports placing
-     arbitrary data blobs at the very beginning of ZIP archives. Archives written using either feature are still
-     readable by any ZIP tool.
-
-     - Archive appending: The simple way to add a single file to an archive is to call this function:
-
-      mz_bool mz_zip_add_mem_to_archive_file_in_place(const char *pZip_filename, const char *pArchive_name,
-        const void *pBuf, size_t buf_size, const void *pComment, mz_uint16 comment_size, mz_uint level_and_flags);
-
-     The archive will be created if it doesn't already exist, otherwise it'll be appended to.
-     Note the appending is done in-place and is not an atomic operation, so if something goes wrong
-     during the operation it's possible the archive could be left without a central directory (although the local
-     file headers and file data will be fine, so the archive will be recoverable).
-
-     For more complex archive modification scenarios:
-     1. The safest way is to use a mz_zip_reader to read the existing archive, cloning only those bits you want to
-     preserve into a new archive using using the mz_zip_writer_add_from_zip_reader() function (which compiles the
-     compressed file data as-is). When you're done, delete the old archive and rename the newly written archive, and
-     you're done. This is safe but requires a bunch of temporary disk space or heap memory.
-
-     2. Or, you can convert an mz_zip_reader in-place to an mz_zip_writer using mz_zip_writer_init_from_reader(),
-     append new files as needed, then finalize the archive which will write an updated central directory to the
-     original archive. (This is basically what mz_zip_add_mem_to_archive_file_in_place() does.) There's a
-     possibility that the archive's central directory could be lost with this method if anything goes wrong, though.
-
-     - ZIP archive support limitations:
-     No spanning support. Extraction functions can only handle unencrypted, stored or deflated files.
-     Requires streams capable of seeking.
-
-   * This is a header file library, like stb_image.c. To get only a header file, either cut and paste the
-     below header, or create miniz.h, #define MINIZ_HEADER_FILE_ONLY, and then include miniz.c from it.
-
-   * Important: For best perf. be sure to customize the below macros for your target platform:
-     #define MINIZ_USE_UNALIGNED_LOADS_AND_STORES 1
-     #define MINIZ_LITTLE_ENDIAN 1
-     #define MINIZ_HAS_64BIT_REGISTERS 1
-
-   * On platforms using glibc, Be sure to "#define _LARGEFILE64_SOURCE 1" before including miniz.c to ensure miniz
-     uses the 64-bit variants: fopen64(), stat64(), etc. Otherwise you won't be able to process large files
-     (i.e. 32-bit stat() fails for me on files > 0x7FFFFFFF bytes).

-# Header only C++ tiny glTF library(loader/saver).
-
-`TinyGLTF` is a header only C++11 glTF 2.0 https://github.com/KhronosGroup/glTF library.
-
-`TinyGLTF` uses Niels Lohmann's json library(https://github.com/nlohmann/json), so now it requires C++11 compiler.
-If you are looking for old, C++03 version, please use `devel-picojson` branch(but not maintained anymore).
-
-## Status
-
- - v2.4.0 Experimental RapidJSON support. Experimental C++14 support(C++14 may give better performance)
- - v2.3.0 Modified Material representation according to glTF 2.0 schema(and introduced TextureInfo class)
- - v2.2.0 release(Support loading 16bit PNG. Sparse accessor support)
- - v2.1.0 release(Draco support)
- - v2.0.0 release(22 Aug, 2018)!
-
-### Branches
-
-* `sajson` : Use sajson to parse JSON. Parsing only but faster compile time(2x reduction compared to json.hpp and RapidJson)

-## Note on extension property
-
-In extension(`ExtensionMap`), JSON number value is parsed as int or float(number) and stored as `tinygltf::Value` object. If you want a floating point value from `tinygltf::Value`, use `GetNumberAsDouble()` method.
-
-`IsNumber()` returns true if the underlying value is an int value or a floating point value.
-
-## Examples
-
-* [glview](examples/glview) : Simple glTF geometry viewer.
-* [validator](examples/validator) : Simple glTF validator with JSON schema.
-* [basic](examples/basic) : Basic glTF viewer with texturing support.

-TinyGLTF uses the following third party libraries.
-
-* json.hpp : Copyright (c) 2013-2017 Niels Lohmann. MIT license.
-* base64 : Copyright (C) 2004-2008 René Nyffenegger
-* stb_image.h : v2.08 - public domain image loader - [Github link](https://github.com/nothings/stb/blob/master/stb_image.h)
-* stb_image_write.h : v1.09 - public domain image writer - [Github link](https://github.com/nothings/stb/blob/master/stb_image_write.h)
-
-
-## Build and example
-
-Copy `stb_image.h`, `stb_image_write.h`, `json.hpp` and `tiny_gltf.h` to your project.
-
-### Loading glTF 2.0 model
-
-```c++
-// Define these only in *one* .cc file.
-#define TINYGLTF_IMPLEMENTATION
-#define STB_IMAGE_IMPLEMENTATION
-#define STB_IMAGE_WRITE_IMPLEMENTATION
-// #define TINYGLTF_NOEXCEPTION // optional. disable exception handling.
-#include "tiny_gltf.h"
-
-using namespace tinygltf;
-
-Model model;
-TinyGLTF loader;
-std::string err;
-std::string warn;
-
-bool ret = loader.LoadASCIIFromFile(&model, &err, &warn, argv[1]);
-//bool ret = loader.LoadBinaryFromFile(&model, &err, &warn, argv[1]); // for binary glTF(.glb)
-
-if (!warn.empty()) {
-  printf("Warn: %s\n", warn.c_str());
-}
-
-if (!err.empty()) {
-  printf("Err: %s\n", err.c_str());
-}
-
-if (!ret) {
-  printf("Failed to parse glTF\n");
-  return -1;
-}
-```
-
-#### Loader options
-
-* `TinyGLTF::SetPreserveimageChannels(bool onoff)`. `true` to preserve image channels as stored in image file for loaded image. `false` by default for backward compatibility(image channels are widen to `RGBA` 4 channels). Effective only when using builtin image loader(STB image loader).
-
-## Compile options
-
-* `TINYGLTF_NOEXCEPTION` : Disable C++ exception in JSON parsing. You can use `-fno-exceptions` or by defining the symbol `JSON_NOEXCEPTION` and `TINYGLTF_NOEXCEPTION`  to fully remove C++ exception codes when compiling TinyGLTF.
-* `TINYGLTF_NO_STB_IMAGE` : Do not load images with stb_image. Instead use `TinyGLTF::SetImageLoader(LoadimageDataFunction LoadImageData, void *user_data)` to set a callback for loading images.
-* `TINYGLTF_NO_STB_IMAGE_WRITE` : Do not write images with stb_image_write. Instead use `TinyGLTF::SetImageWriter(WriteimageDataFunction WriteImageData, void *user_data)` to set a callback for writing images.
-* `TINYGLTF_NO_EXTERNAL_IMAGE` : Do not try to load external image file. This option would be helpful if you do not want to load image files during glTF parsing.
-* `TINYGLTF_ANDROID_LOAD_FROM_ASSETS`: Load all files from packaged app assets instead of the regular file system. **Note:** You must pass a valid asset manager from your android app to `tinygltf::asset_manager` beforehand.
-* `TINYGLTF_ENABLE_DRACO`: Enable Draco compression. User must provide include path and link correspnding libraries in your project file.
-* `TINYGLTF_NO_INCLUDE_JSON `: Disable including `json.hpp` from within `tiny_gltf.h` because it has been already included before or you want to include it using custom path before including `tiny_gltf.h`.
-* `TINYGLTF_NO_INCLUDE_STB_IMAGE `: Disable including `stb_image.h` from within `tiny_gltf.h` because it has been already included before or you want to include it using custom path before including `tiny_gltf.h`.
-* `TINYGLTF_NO_INCLUDE_STB_IMAGE_WRITE `: Disable including `stb_image_write.h` from within `tiny_gltf.h` because it has been already included before or you want to include it using custom path before including `tiny_gltf.h`.
-* `TINYGLTF_USE_RAPIDJSON` : Use RapidJSON as a JSON parser/serializer. RapidJSON files are not included in TinyGLTF repo. Please set an include path to RapidJSON if you enable this featrure.
-* `TINYGLTF_USE_CPP14` : Use C++14 feature(requires C++14 compiler). This may give better performance than C++11.

-
-## Running tests.
-
-### glTF parsing test
-
-#### Setup
-
-Python 2.6 or 2.7 required.
-Git clone https://github.com/KhronosGroup/glTF-Sample-Models to your local dir.
-
-#### Run parsing test
-
-After building `loader_example`, edit `test_runner.py`, then,
-
-```bash
-$ python test_runner.py
-```
-
-### Unit tests
-
-```bash
-$ cd tests
-$ make
-$ ./tester
-$ ./tester_noexcept
-```
-
-### Fuzzing tests
-
-See `tests/fuzzer` for details.
-
-After running fuzzer on Ryzen9 3950X a week, at least `LoadASCIIFromString` looks safe except for out-of-memory error in Fuzzer.
-We may be better to introduce bounded memory size checking when parsing glTF data.

-@brief exception indicating a parse error
-
-This exception is thrown by the library when a parse error occurs. Parse errors
-can occur during the deserialization of JSON text, CBOR, MessagePack, as well
-as when using JSON Patch.
-
-Member @a byte holds the byte index of the last read character in the input
-file.
-
-Exceptions have ids 1xx.
-
-name / id                      | example message | description
------------------------------- | --------------- | -------------------------
-json.exception.parse_error.101 | parse error at 2: unexpected end of input; expected string literal | This error indicates a syntax error while deserializing a JSON text. The error message describes that an unexpected token (character) was encountered, and the member @a byte indicates the error position.
-json.exception.parse_error.102 | parse error at 14: missing or wrong low surrogate | JSON uses the `\uxxxx` format to describe Unicode characters. Code points above above 0xFFFF are split into two `\uxxxx` entries ("surrogate pairs"). This error indicates that the surrogate pair is incomplete or contains an invalid code point.
-json.exception.parse_error.103 | parse error: code points above 0x10FFFF are invalid | Unicode supports code points up to 0x10FFFF. Code points above 0x10FFFF are invalid.
-json.exception.parse_error.104 | parse error: JSON patch must be an array of objects | [RFC 6902](https://tools.ietf.org/html/rfc6902) requires a JSON Patch document to be a JSON document that represents an array of objects.
-json.exception.parse_error.105 | parse error: operation must have string member 'op' | An operation of a JSON Patch document must contain exactly one "op" member, whose value indicates the operation to perform. Its value must be one of "add", "remove", "replace", "move", "copy", or "test"; other values are errors.

-json.exception.invalid_iterator.202 | iterator does not fit current value | In an erase or insert function, the passed iterator @a pos does not belong to the JSON value for which the function was called. It hence does not define a valid position for the deletion/insertion.
-json.exception.invalid_iterator.203 | iterators do not fit current value | Either iterator passed to function @ref erase(IteratorType first, IteratorType last) does not belong to the JSON value from which values shall be erased. It hence does not define a valid range to delete values from.
-json.exception.invalid_iterator.204 | iterators out of range | When an iterator range for a primitive type (number, boolean, or string) is passed to a constructor or an erase function, this range has to be exactly (@ref begin(), @ref end()), because this is the only way the single stored value is expressed. All other ranges are invalid.

-
-    This function scans a string according to Sect. 6 of RFC 7159.
-
-    The function is realized with a deterministic finite state machine derived
-    from the grammar described in RFC 7159. Starting in state "init", the
-    input is read and used to determined the next state. Only state "done"
-    accepts the number. State "error" is a trap state to model errors. In the
-    table below, "anything" means any character but the ones listed before.
-
-    state    | 0        | 1-9      | e E      | +       | -       | .        | anything

-
-    The state machine is realized with one label per state (prefixed with
-    "scan_number_") and `goto` statements between them. The state machine
-    contains cycles, but any cycle can be left when EOF is read. Therefore,
-    the function is guaranteed to terminate.
-
-    During scanning, the read bytes are stored in token_buffer. This string is
-    then converted to a signed integer, an unsigned integer, or a
-    floating-point number.
-
-    @return token_type::value_unsigned, token_type::value_integer, or
-            token_type::value_float if number could be successfully scanned,
-            token_type::parse_error otherwise
-
-    @note The scanner is independent of the current locale. Internally, the
-          locale's decimal point is used instead of `.` to work with the
-          locale-dependent converters.

-@brief a template for a bidirectional iterator for the @ref basic_json class
-This class implements a both iterators (iterator and const_iterator) for the
-@ref basic_json class.
-@note An iterator is called *initialized* when a pointer to a JSON value has
-      been set (e.g., by a constructor or a copy assignment). If the iterator is
-      default-constructed, it is *uninitialized* and most methods are undefined.
-      **The library uses assertions to detect calls on uninitialized iterators.**
-@requirement The class satisfies the following concept requirements:
--
-[BidirectionalIterator](https://en.cppreference.com/w/cpp/named_req/BidirectionalIterator):
-  The iterator that can be moved can be moved in both directions (i.e.
-  incremented and decremented).
-@since version 1.0.0, simplified in version 2.0.9, change to bidirectional
-       iterators in version 3.0.0 (see https://github.com/nlohmann/json/issues/593)

-@brief a template for a reverse iterator class
-
-@tparam Base the base iterator type to reverse. Valid types are @ref
-iterator (to create @ref reverse_iterator) and @ref const_iterator (to
-create @ref const_reverse_iterator).
-
-@requirement The class satisfies the following concept requirements:
--
-[BidirectionalIterator](https://en.cppreference.com/w/cpp/named_req/BidirectionalIterator):
-  The iterator that can be moved can be moved in both directions (i.e.
-  incremented and decremented).
-- [OutputIterator](https://en.cppreference.com/w/cpp/named_req/OutputIterator):
-  It is possible to write to the pointed-to element (only if @a Base is
-  @ref iterator).

-//
-// or
-//
-//      2^(q - 2 + alpha) <= c * w < 2^(q + gamma)

-// The choice of (alpha,gamma) determines the size of the table and the form of
-// the digit generation procedure. Using (alpha,gamma)=(-60,-32) works out well
-// in practice:
-//
-// The idea is to cut the number c * w = f * 2^e into two parts, which can be
-// processed independently: An integral part p1, and a fractional part p2:
-//
-//      f * 2^e = ( (f div 2^-e) * 2^-e + (f mod 2^-e) ) * 2^e
-//              = (f div 2^-e) + (f mod 2^-e) * 2^e
-//              = p1 + p2 * 2^e
-//
-// The conversion of p1 into decimal form requires a series of divisions and
-// modulos by (a power of) 10. These operations are faster for 32-bit than for
-// 64-bit integers, so p1 should ideally fit into a 32-bit integer. This can be
-// achieved by choosing
-//
-//      -e >= 32   or   e <= -32 := gamma
-//
-// In order to convert the fractional part
-//
-//      p2 * 2^e = p2 / 2^-e = d[-1] / 10^1 + d[-2] / 10^2 + ...
-//
-// into decimal form, the fraction is repeatedly multiplied by 10 and the digits
-// d[-i] are extracted in order:
-//
-//      (10 * p2) div 2^-e = d[-1]
-//      (10 * p2) mod 2^-e = d[-2] / 10^1 + ...
-//

-
-@requirement The class satisfies the following concept requirements:
-- Basic
- - [DefaultConstructible](https://en.cppreference.com/w/cpp/named_req/DefaultConstructible):
-   JSON values can be default constructed. The result will be a JSON null
-   value.
- - [MoveConstructible](https://en.cppreference.com/w/cpp/named_req/MoveConstructible):
-   A JSON value can be constructed from an rvalue argument.
- - [CopyConstructible](https://en.cppreference.com/w/cpp/named_req/CopyConstructible):
-   A JSON value can be copy-constructed from an lvalue expression.
- - [MoveAssignable](https://en.cppreference.com/w/cpp/named_req/MoveAssignable):
-   A JSON value van be assigned from an rvalue argument.
- - [CopyAssignable](https://en.cppreference.com/w/cpp/named_req/CopyAssignable):
-   A JSON value can be copy-assigned from an lvalue expression.
- - [Destructible](https://en.cppreference.com/w/cpp/named_req/Destructible):
-   JSON values can be destructed.
-- Layout
- - [StandardLayoutType](https://en.cppreference.com/w/cpp/named_req/StandardLayoutType):
-   JSON values have
-   [standard layout](https://en.cppreference.com/w/cpp/language/data_members#Standard_layout):
-   All non-static data members are private and standard layout types, the
-   class has no virtual functions or (virtual) base classes.
-- Library-wide
- - [EqualityComparable](https://en.cppreference.com/w/cpp/named_req/EqualityComparable):
-   JSON values can be compared with `==`, see @ref
-   operator==(const_reference,const_reference).
- - [LessThanComparable](https://en.cppreference.com/w/cpp/named_req/LessThanComparable):
-   JSON values can be compared with `<`, see @ref
-   operator<(const_reference,const_reference).
- - [Swappable](https://en.cppreference.com/w/cpp/named_req/Swappable):
-   Any JSON lvalue or rvalue of can be swapped with any lvalue or rvalue of
-   other compatible types, using unqualified function call @ref swap().
- - [NullablePointer](https://en.cppreference.com/w/cpp/named_req/NullablePointer):
-   JSON values can be compared against `std::nullptr_t` objects which are used
-   to model the `null` value.
-- Container
- - [Container](https://en.cppreference.com/w/cpp/named_req/Container):
-   JSON values can be used like STL containers and provide iterator access.
- - [ReversibleContainer](https://en.cppreference.com/w/cpp/named_req/ReversibleContainer);
-   JSON values can be used like STL containers and provide reverse iterator
-   access.
-
-@invariant The member variables @a m_value and @a m_type have the following
-relationship:
-- If `m_type == value_t::object`, then `m_value.object != nullptr`.
-- If `m_type == value_t::array`, then `m_value.array != nullptr`.
-- If `m_type == value_t::string`, then `m_value.string != nullptr`.
-The invariants are checked by member function assert_invariant().

-    @brief a type for an object
-
-    [RFC 7159](http://rfc7159.net/rfc7159) describes JSON objects as follows:
-    > An object is an unordered collection of zero or more name/value pairs,
-    > where a name is a string and a value is a string, number, boolean, null,
-    > object, or array.
-
-    To store objects in C++, a type is defined by the template parameters
-    described below.
-
-    @tparam ObjectType  the container to store objects (e.g., `std::map` or
-    `std::unordered_map`)
-    @tparam StringType the type of the keys or names (e.g., `std::string`).
-    The comparison function `std::less<StringType>` is used to order elements
-    inside the container.
-    @tparam AllocatorType the allocator to use for objects (e.g.,
-    `std::allocator`)
-
-    #### Default type
-
-    With the default values for @a ObjectType (`std::map`), @a StringType
-    (`std::string`), and @a AllocatorType (`std::allocator`), the default
-    value for @a object_t is:
-
-    @code {.cpp}
-    std::map<
-      std::string, // key_type
-      basic_json, // value_type
-      std::less<std::string>, // key_compare
-      std::allocator<std::pair<const std::string, basic_json>> // allocator_type
-    >
-    @endcode
-
-    #### Behavior
-
-    The choice of @a object_t influences the behavior of the JSON class. With
-    the default type, objects have the following behavior:
-
-    - When all names are unique, objects will be interoperable in the sense
-      that all software implementations receiving that object will agree on
-      the name-value mappings.
-    - When the names within an object are not unique, it is unspecified which
-      one of the values for a given key will be chosen. For instance,
-      `{"key": 2, "key": 1}` could be equal to either `{"key": 1}` or
-      `{"key": 2}`.
-    - Internally, name/value pairs are stored in lexicographical order of the
-      names. Objects will also be serialized (see @ref dump) in this order.
-      For instance, `{"b": 1, "a": 2}` and `{"a": 2, "b": 1}` will be stored
-      and serialized as `{"a": 2, "b": 1}`.
-    - When comparing objects, the order of the name/value pairs is irrelevant.
-      This makes objects interoperable in the sense that they will not be
-      affected by these differences. For instance, `{"b": 1, "a": 2}` and
-      `{"a": 2, "b": 1}` will be treated as equal.
-
-    #### Limits
-
-    [RFC 7159](http://rfc7159.net/rfc7159) specifies:
-    > An implementation may set limits on the maximum depth of nesting.
-
-    In this class, the object's limit of nesting is not explicitly constrained.
-    However, a maximum depth of nesting may be introduced by the compiler or
-    runtime environment. A theoretical limit can be queried by calling the
-    @ref max_size function of a JSON object.
-
-    #### Storage
-
-    Objects are stored as pointers in a @ref basic_json type. That is, for any
-    access to object values, a pointer of type `object_t*` must be
-    dereferenced.
-
-    @sa @ref array_t -- type for an array value
-
-    @since version 1.0.0
-
-    @note The order name/value pairs are added to the object is *not*
-    preserved by the library. Therefore, iterating an object may return
-    name/value pairs in a different order than they were originally stored. In
-    fact, keys will be traversed in alphabetical order as `std::map` with
-    `std::less` is used by default. Please note this behavior conforms to [RFC
-    7159](http://rfc7159.net/rfc7159), because any order implements the
-    specified "unordered" nature of JSON objects.

-    @ref max_size function of a JSON array.
-

-    @brief a type for a string
-
-    [RFC 7159](http://rfc7159.net/rfc7159) describes JSON strings as follows:
-    > A string is a sequence of zero or more Unicode characters.
-
-    To store objects in C++, a type is defined by the template parameter
-    described below. Unicode values are split by the JSON class into
-    byte-sized characters during deserialization.
-
-    @tparam StringType  the container to store strings (e.g., `std::string`).
-    Note this container is used for keys/names in objects, see @ref object_t.
-
-    #### Default type
-
-    With the default values for @a StringType (`std::string`), the default
-    value for @a string_t is:
-
-    @code {.cpp}
-    std::string
-    @endcode
-
-    #### Encoding
-
-    Strings are stored in UTF-8 encoding. Therefore, functions like
-    `std::string::size()` or `std::string::length()` return the number of
-    bytes in the string rather than the number of characters or glyphs.
-
-    #### String comparison
-
-    [RFC 7159](http://rfc7159.net/rfc7159) states:
-    > Software implementations are typically required to test names of object
-    > members for equality. Implementations that transform the textual
-    > representation into sequences of Unicode code units and then perform the
-    > comparison numerically, code unit by code unit, are interoperable in the
-    > sense that implementations will agree in all cases on equality or
-    > inequality of two strings. For example, implementations that compare
-    > strings with escaped characters unconverted may incorrectly find that
-    > `"a\\b"` and `"a\u005Cb"` are not equal.
-
-    This implementation is interoperable as it does compare strings code unit
-    by code unit.
-
-    #### Storage

-    String values are stored as pointers in a @ref basic_json type. That is,

-
-    This description includes both integer and floating-point numbers.
-    However, C++ allows more precise storage if it is known whether the number
-    is a signed integer, an unsigned integer or a floating-point number.
-    Therefore, three different types, @ref number_integer_t, @ref

-    @endcode

-      number. Internally, the value will be stored as decimal number. For

-

-
-    When the default type is used, the maximal integer number that can be

-    that can be stored is `-9223372036854775808` (INT64_MIN). Integer numbers
-    that are out of range will yield over/underflow when used in a

-    will be automatically be stored as @ref number_unsigned_t or @ref

-
-    [RFC 7159](http://rfc7159.net/rfc7159) further states:

-    @brief per-element parser callback type
-
-    With a parser callback function, the result of parsing a JSON text can be
-    influenced. When passed to @ref parse, it is called on certain events
-    (passed as @ref parse_event_t via parameter @a event) with a set recursion
-    depth @a depth and context JSON value @a parsed. The return value of the
-    callback function is a boolean indicating whether the element that emitted
-    the callback shall be kept or not.
-
-    We distinguish six scenarios (determined by the event type) in which the
-    callback function can be called. The following table describes the values
-    of the parameters @a depth, @a event, and @a parsed.
-
-    parameter @a event | description | parameter @a depth | parameter @a parsed
-    ------------------ | ----------- | ------------------ | -------------------
-    parse_event_t::object_start | the parser read `{` and started to process a JSON object | depth of the parent of the JSON object | a JSON value with type discarded
-    parse_event_t::key | the parser read a key of a value in an object | depth of the currently parsed JSON object | a JSON string containing the key
-    parse_event_t::object_end | the parser read `}` and finished processing a JSON object | depth of the parent of the JSON object | the parsed JSON object
-    parse_event_t::array_start | the parser read `[` and started to process a JSON array | depth of the parent of the JSON array | a JSON value with type discarded
-    parse_event_t::array_end | the parser read `]` and finished processing a JSON array | depth of the parent of the JSON array | the parsed JSON array
-    parse_event_t::value | the parser finished reading a JSON value | depth of the value | the parsed JSON value

-    Discarding a value (i.e., returning `false`) has different effects
-    depending on the context in which function was called:
-
-    - Discarded values in structured types are skipped. That is, the parser
-      will behave as if the discarded value was never read.
-    - In case a value outside a structured type is skipped, it is replaced
-      with `null`. This case happens if the top-level element is skipped.

-    @brief create a container (array or object) from an initializer list
-
-    Creates a JSON value of type array or object from the passed initializer
-    list @a init. In case @a type_deduction is `true` (default), the type of
-    the JSON value to be created is deducted from the initializer list @a init
-    according to the following rules:
-
-    1. If the list is empty, an empty JSON object value `{}` is created.
-    2. If the list consists of pairs whose first element is a string, a JSON
-       object value is created where the first elements of the pairs are
-       treated as keys and the second elements are as values.
-    3. In all other cases, an array is created.
-
-    The rules aim to create the best fit between a C++ initializer list and
-    JSON values. The rationale is as follows:
-
-    1. The empty initializer list is written as `{}` which is exactly an empty
-       JSON object.
-    2. C++ has no way of describing mapped types other than to list a list of
-       pairs. As JSON requires that keys must be of type string, rule 2 is the
-       weakest constraint one can pose on initializer lists to interpret them
-       as an object.
-    3. In all other cases, the initializer list could not be interpreted as
-       JSON object type, so interpreting it as JSON array type is safe.
-
-    With the rules described above, the following JSON values cannot be
-    expressed by an initializer list:
-
-    - the empty array (`[]`): use @ref array(initializer_list_t)
-      with an empty initializer list in this case
-    - arrays whose elements satisfy rule 2: use @ref
-      array(initializer_list_t) with the same initializer list
-      in this case
-
-    @note When used without parentheses around an empty initializer list, @ref
-    basic_json() is called instead of this function, yielding the JSON null
-    value.
-
-    @param[in] init  initializer list with JSON values
-
-    @param[in] type_deduction internal parameter; when set to `true`, the type
-    of the JSON value is deducted from the initializer list @a init; when set
-    to `false`, the type provided via @a manual_type is forced. This mode is
-    used by the functions @ref array(initializer_list_t) and
-    @ref object(initializer_list_t).
-
-    @param[in] manual_type internal parameter; when @a type_deduction is set
-    to `false`, the created JSON value will use the provided type (only @ref
-    value_t::array and @ref value_t::object are valid); when @a type_deduction
-    is set to `true`, this parameter has no effect
-
-    @throw type_error.301 if @a type_deduction is `false`, @a manual_type is
-    `value_t::object`, but @a init contains an element which is not a pair
-    whose first element is a string. In this case, the constructor could not
-    create an object. If @a type_deduction would have be `true`, an array
-    would have been created. See @ref object(initializer_list_t)

-    Explicit type conversion between the JSON value and a compatible value.
-    The value is filled into the input parameter by calling the @ref json_serializer<ValueType>
-    `from_json()` method.
-
-    The function is equivalent to executing
-    @code {.cpp}
-    ValueType v;
-    JSONSerializer<ValueType>::from_json(*this, v);
-    @endcode
-
-    This overloads is chosen if:
-    - @a ValueType is not @ref basic_json,
-    - @ref json_serializer<ValueType> has a `from_json()` method of the form
-      `void from_json(const basic_json&, ValueType&)`, and
-
-    @tparam ValueType the input parameter type.
-
-    @return the input parameter, allowing chaining calls.
-
-    @throw what @ref json_serializer<ValueType> `from_json()` method throws
-
-    @liveexample{The example below shows several conversions from JSON values
-    to other types. There a few things to note: (1) Floating-point numbers can
-    be converted to integers\, (2) A JSON array can be converted to a standard

-    - Two JSON values are equal if (1) they are from the same type and (2)
-      their stored values are the same according to their respective
-      `operator==`.
-    - Integer and floating-point numbers are automatically converted before
-      comparison. Note than two NaN values are always treated as unequal.

-    default. To compare floating-point while respecting an epsilon, an alternative

-    @brief applies a JSON Merge Patch
-
-    The merge patch format is primarily intended for use with the HTTP PATCH
-    method as a means of describing a set of modifications to a target
-    resource's content. This function applies a merge patch to the current
-    JSON value.
-
-    The function implements the following algorithm from Section 2 of
-    [RFC 7396 (JSON Merge Patch)](https://tools.ietf.org/html/rfc7396):
-
-    ```
-    define MergePatch(Target, Patch):
-      if Patch is an Object:
-        if Target is not an Object:
-          Target = {} // Ignore the contents and set it to an empty Object
-        for each Name/Value pair in Patch:
-          if Value is null:
-            if Name exists in Target:
-              remove the Name/Value pair from Target
-          else:
-            Target[Name] = MergePatch(Target[Name], Value)
-        return Target
-      else:
-        return Patch
-    ```
-
-    Thereby, `Target` is the current object; that is, the patch is applied to
-    the current value.

-
-// DOCUMENTATION
-//
-// Limitations:
-//    - no 12-bit-per-channel JPEG
-//    - no JPEGs with arithmetic coding
-//    - GIF always returns *comp=4
-//
-// Basic usage (see HDR discussion below for HDR usage):
-//    int x,y,n;
-//    unsigned char *data = stbi_load(filename, &x, &y, &n, 0);
-//    // ... process data if not NULL ...
-//    // ... x = width, y = height, n = # 8-bit components per pixel ...
-//    // ... replace '0' with '1'..'4' to force that many components per pixel
-//    // ... but 'n' will always be the number that it would have been if you said 0
-//    stbi_image_free(data)
-//
-// Standard parameters:
-//    int *x                 -- outputs image width in pixels
-//    int *y                 -- outputs image height in pixels
-//    int *channels_in_file  -- outputs # of image components in image file
-//    int desired_channels   -- if non-zero, # of image components requested in result
-//
-// The return value from an image loader is an 'unsigned char *' which points
-// to the pixel data, or NULL on an allocation failure or if the image is
-// corrupt or invalid. The pixel data consists of *y scanlines of *x pixels,
-// with each pixel consisting of N interleaved 8-bit components; the first
-// pixel pointed to is top-left-most in the image. There is no padding between
-// image scanlines or between pixels, regardless of format. The number of
-// components N is 'desired_channels' if desired_channels is non-zero, or
-// *channels_in_file otherwise. If desired_channels is non-zero,
-// *channels_in_file has the number of components that _would_ have been
-// output otherwise. E.g. if you set desired_channels to 4, you will always
-// get RGBA output, but you can check *channels_in_file to see if it's trivially
-// opaque because e.g. there were only 3 channels in the source image.
-//
-// An output image with N components has the following components interleaved
-// in this order in each pixel:
-//
-//     N=#comp     components
-//       1           grey
-//       2           grey, alpha
-//       3           red, green, blue
-//       4           red, green, blue, alpha
-//
-// If image loading fails for any reason, the return value will be NULL,
-// and *x, *y, *channels_in_file will be unchanged. The function
-// stbi_failure_reason() can be queried for an extremely brief, end-user
-// unfriendly explanation of why the load failed. Define STBI_NO_FAILURE_STRINGS
-// to avoid compiling these strings at all, and STBI_FAILURE_USERMSG to get slightly
-// more user-friendly ones.
-//
-// Paletted PNG, BMP, GIF, and PIC images are automatically depalettized.
-//
-// ===========================================================================
-//
-// UNICODE:
-//
-//   If compiling for Windows and you wish to use Unicode filenames, compile
-//   with
-//       #define STBI_WINDOWS_UTF8
-//   and pass utf8-encoded filenames. Call stbi_convert_wchar_to_utf8 to convert
-//   Windows wchar_t filenames to utf8.
-//
-// ===========================================================================
-//
-// Philosophy
-//
-// stb libraries are designed with the following priorities:
-//
-//    1. easy to use
-//    2. easy to maintain
-//    3. good performance
-//
-// Sometimes I let "good performance" creep up in priority over "easy to maintain",
-// and for best performance I may provide less-easy-to-use APIs that give higher
-// performance, in addition to the easy-to-use ones. Nevertheless, it's important
-// to keep in mind that from the standpoint of you, a client of this library,
-// all you care about is #1 and #3, and stb libraries DO NOT emphasize #3 above all.
-//
-// Some secondary priorities arise directly from the first two, some of which
-// provide more explicit reasons why performance can't be emphasized.
-//
-//    - Portable ("ease of use")
-//    - Small source code footprint ("easy to maintain")
-//    - No dependencies ("ease of use")
-//
-// ===========================================================================
-//
-// I/O callbacks
-//
-// I/O callbacks allow you to read from arbitrary sources, like packaged
-// files or some other source. Data read from callbacks are processed
-// through a small internal buffer (currently 128 bytes) to try to reduce
-// overhead.
-//
-// The three functions you must define are "read" (reads some bytes of data),
-// "skip" (skips some bytes of data), "eof" (reports if the stream is at the end).
-//
-// ===========================================================================
-//
-// SIMD support
-//
-// The JPEG decoder will try to automatically use SIMD kernels on x86 when
-// supported by the compiler. For ARM Neon support, you must explicitly
-// request it.
-//
-// (The old do-it-yourself SIMD API is no longer supported in the current
-// code.)
-//
-// On x86, SSE2 will automatically be used when available based on a run-time
-// test; if not, the generic C versions are used as a fall-back. On ARM targets,
-// the typical path is to have separate builds for NEON and non-NEON devices
-// (at least this is true for iOS and Android). Therefore, the NEON support is
-// toggled by a build flag: define STBI_NEON to get NEON loops.
-//
-// If for some reason you do not want to use any of SIMD code, or if
-// you have issues compiling it, you can disable it entirely by
-// defining STBI_NO_SIMD.
-//
-// ===========================================================================
-//
-// HDR image support   (disable by defining STBI_NO_HDR)
-//
-// stb_image supports loading HDR images in general, and currently the Radiance
-// .HDR file format specifically. You can still load any file through the existing
-// interface; if you attempt to load an HDR file, it will be automatically remapped
-// to LDR, assuming gamma 2.2 and an arbitrary scale factor defaulting to 1;
-// both of these constants can be reconfigured through this interface:
-//
-//     stbi_hdr_to_ldr_gamma(2.2f);
-//     stbi_hdr_to_ldr_scale(1.0f);
-//
-// (note, do not use _inverse_ constants; stbi_image will invert them
-// appropriately).
-//
-// Additionally, there is a new, parallel interface for loading files as
-// (linear) floats to preserve the full dynamic range:
-//
-//    float *data = stbi_loadf(filename, &x, &y, &n, 0);
-//
-// If you load LDR images through this interface, those images will
-// be promoted to floating point values, run through the inverse of
-// constants corresponding to the above:
-//
-//     stbi_ldr_to_hdr_scale(1.0f);
-//     stbi_ldr_to_hdr_gamma(2.2f);
-//
-// Finally, given a filename (or an open file or memory block--see header
-// file for details) containing image data, you can query for the "most
-// appropriate" interface to use (that is, whether the image is HDR or
-// not), using:
-//
-//     stbi_is_hdr(char *filename);
-//
-// ===========================================================================
-//
-// iPhone PNG support:
-//
-// By default we convert iphone-formatted PNGs back to RGB, even though
-// they are internally encoded differently. You can disable this conversion
-// by calling stbi_convert_iphone_png_to_rgb(0), in which case
-// you will always just get the native iphone "format" through (which
-// is BGR stored in RGB).
-//
-// Call stbi_set_unpremultiply_on_load(1) as well to force a divide per
-// pixel to remove any premultiplied alpha *only* if the image file explicitly
-// says there's premultiplied data (currently only happens in iPhone images,
-// and only if iPhone convert-to-rgb processing is on).
-//
-// ===========================================================================
-//
-// ADDITIONAL CONFIGURATION
-//
-//  - You can suppress implementation of any of the decoders to reduce
-//    your code footprint by #defining one or more of the following
-//    symbols before creating the implementation.
-//
-//        STBI_NO_JPEG
-//        STBI_NO_PNG
-//        STBI_NO_BMP
-//        STBI_NO_PSD
-//        STBI_NO_TGA
-//        STBI_NO_GIF
-//        STBI_NO_HDR
-//        STBI_NO_PIC
-//        STBI_NO_PNM   (.ppm and .pgm)
-//
-//  - You can request *only* certain decoders and suppress all other ones
-//    (this will be more forward-compatible, as addition of new decoders
-//    doesn't require you to disable them explicitly):
-//
-//        STBI_ONLY_JPEG
-//        STBI_ONLY_PNG
-//        STBI_ONLY_BMP
-//        STBI_ONLY_PSD
-//        STBI_ONLY_TGA
-//        STBI_ONLY_GIF
-//        STBI_ONLY_HDR
-//        STBI_ONLY_PIC
-//        STBI_ONLY_PNM   (.ppm and .pgm)
-//
-//   - If you use STBI_NO_PNG (or _ONLY_ without PNG), and you still
-//     want the zlib decoder to be available, #define STBI_SUPPORT_ZLIB

-/* stb_image_write - v1.11 - public domain - http://nothings.org/stb/stb_image_write.h
-   writes out PNG/BMP/TGA/JPEG/HDR images to C stdio - Sean Barrett 2010-2015
-                                     no warranty implied; use at your own risk
-
-   Before #including,
-
-       #define STB_IMAGE_WRITE_IMPLEMENTATION
-
-   in the file that you want to have the implementation.
-
-   Will probably not work correctly with strict-aliasing optimizations.
-
-   If using a modern Microsoft Compiler, non-safe versions of CRT calls may cause 
-   compilation warnings or even errors. To avoid this, also before #including,
-
-       #define STBI_MSC_SECURE_CRT
-
-ABOUT:
-
-   This header file is a library for writing images to C stdio or a callback.
-
-   The PNG output is not optimal; it is 20-50% larger than the file
-   written by a decent optimizing implementation; though providing a custom
-   zlib compress function (see STBIW_ZLIB_COMPRESS) can mitigate that.
-   This library is designed for source code compactness and simplicity,
-   not optimal image file size or run-time performance.
-
-BUILDING:
-
-   You can #define STBIW_ASSERT(x) before the #include to avoid using assert.h.
-   You can #define STBIW_MALLOC(), STBIW_REALLOC(), and STBIW_FREE() to replace
-   malloc,realloc,free.
-   You can #define STBIW_MEMMOVE() to replace memmove()
-   You can #define STBIW_ZLIB_COMPRESS to use a custom zlib-style compress function
-   for PNG compression (instead of the builtin one), it must have the following signature:
-   unsigned char * my_compress(unsigned char *data, int data_len, int *out_len, int quality);
-   The returned data will be freed with STBIW_FREE() (free() by default),
-   so it must be heap allocated with STBIW_MALLOC() (malloc() by default),
-
-UNICODE:
-
-   If compiling for Windows and you wish to use Unicode filenames, compile
-   with
-       #define STBIW_WINDOWS_UTF8
-   and pass utf8-encoded filenames. Call stbiw_convert_wchar_to_utf8 to convert
-   Windows wchar_t filenames to utf8.
-
-USAGE:
-
-   There are five functions, one for each image file format:
-
-     int stbi_write_png(char const *filename, int w, int h, int comp, const void *data, int stride_in_bytes);
-     int stbi_write_bmp(char const *filename, int w, int h, int comp, const void *data);
-     int stbi_write_tga(char const *filename, int w, int h, int comp, const void *data);
-     int stbi_write_jpg(char const *filename, int w, int h, int comp, const void *data, int quality);
-     int stbi_write_hdr(char const *filename, int w, int h, int comp, const float *data);
-
-     void stbi_flip_vertically_on_write(int flag); // flag is non-zero to flip data vertically
-
-   There are also five equivalent functions that use an arbitrary write function. You are
-   expected to open/close your file-equivalent before and after calling these:
-
-     int stbi_write_png_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void  *data, int stride_in_bytes);
-     int stbi_write_bmp_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void  *data);
-     int stbi_write_tga_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void  *data);
-     int stbi_write_hdr_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const float *data);
-     int stbi_write_jpg_to_func(stbi_write_func *func, void *context, int x, int y, int comp, const void *data, int quality);
-
-   where the callback is:
-      void stbi_write_func(void *context, void *data, int size);
-
-   You can configure it with these global variables:
-      int stbi_write_tga_with_rle;             // defaults to true; set to 0 to disable RLE
-      int stbi_write_png_compression_level;    // defaults to 8; set to higher for more compression
-      int stbi_write_force_png_filter;         // defaults to -1; set to 0..5 to force a filter mode
-
-
-   You can define STBI_WRITE_NO_STDIO to disable the file variant of these
-   functions, so the library will not use stdio.h at all. However, this will
-   also disable HDR writing, because it requires stdio for formatted output.
-
-   Each function returns 0 on failure and non-0 on success.
-
-   The functions create an image file defined by the parameters. The image
-   is a rectangle of pixels stored from left-to-right, top-to-bottom.
-   Each pixel contains 'comp' channels of data stored interleaved with 8-bits
-   per channel, in the following order: 1=Y, 2=YA, 3=RGB, 4=RGBA. (Y is
-   monochrome color.) The rectangle is 'w' pixels wide and 'h' pixels tall.
-   The *data pointer points to the first byte of the top-left-most pixel.
-   For PNG, "stride_in_bytes" is the distance in bytes from the first byte of
-   a row of pixels to the first byte of the next row of pixels.
-
-   PNG creates output files with the same number of components as the input.
-   The BMP format expands Y to RGB in the file format and does not
-   output alpha.
-
-   PNG supports writing rectangles of data even when the bytes storing rows of
-   data are not consecutive in memory (e.g. sub-rectangles of a larger image),
-   by supplying the stride between the beginning of adjacent rows. The other
-   formats do not. (Thus you cannot write a native-format BMP through the BMP
-   writer, both because it is in BGR order and because it may have padding
-   at the end of the line.)
-
-   PNG allows you to set the deflate compression level by setting the global
-   variable 'stbi_write_png_compression_level' (it defaults to 8).
-
-   HDR expects linear float data. Since the format is always 32-bit rgb(e)
-   data, alpha (if provided) is discarded, and for monochrome data it is
-   replicated across all three channels.
-
-   TGA supports RLE or non-RLE compressed data. To use non-RLE-compressed
-   data, set the global variable 'stbi_write_tga_with_rle' to 0.
-   
-   JPEG does ignore alpha channels in input data; quality is between 1 and 100.
-   Higher quality looks better but results in a bigger image.
-   JPEG baseline (no JPEG progressive).

-// Version:
-//  - v2.5.0 Add SetPreserveImageChannels() option to load image data as is.
-//  - v2.4.3 Fix null object output when when material has all default parameters.
-//  - v2.4.2 Decode percent-encoded URI.
-//  - v2.4.1 Fix some glTF object class does not have `extensions` and/or
-//  `extras` property.
-//  - v2.4.0 Experimental RapidJSON and C++14 support(Thanks to @jrkoone).
-//  - v2.3.1 Set default value of minFilter and magFilter in Sampler to -1.
-//  - v2.3.0 Modified Material representation according to glTF 2.0 schema
-//           (and introduced TextureInfo class)
-//           Change the behavior of `Value::IsNumber`. It return true either the
-//           value is int or real.
-//  - v2.2.0 Add loading 16bit PNG support. Add Sparse accessor support(Thanks
-//  to @Ybalrid)
-//  - v2.1.0 Add draco compression.
-//  - v2.0.1 Add comparsion feature(Thanks to @Selmar).
-//  - v2.0.0 glTF 2.0!.

-## Features
-
-* Group(parse multiple group name)
-* Vertex
-* Texcoord
-* Normal
-* Material
-  * Unknown material attributes are returned as key-value(value is string) map.
-* Crease tag('t'). This is OpenSubdiv specific(not in wavefront .obj specification)
-* PBR material extension for .MTL. Its proposed here: http://exocortex.com/blog/extending_wavefront_mtl_to_support_pbr
-* Callback API for custom loading.
-
-
-## TODO
-
-* [ ] Fix obj_sticker example.
-* [ ] More unit test codes.
-* [x] Texture options
-* [ ] Normal vector generation
-  * [ ] Support smoothing groups

-## Usage
-
-### Data format
-
-`attrib_t` contains single and linear array of vertex data(position, normal and texcoord).
-
-```
-attrib_t::vertices => 3 floats per vertex
-
-       v[0]        v[1]        v[2]        v[3]               v[n-1]
-  +-----------+-----------+-----------+-----------+      +-----------+
-  | x | y | z | x | y | z | x | y | z | x | y | z | .... | x | y | z |
-  +-----------+-----------+-----------+-----------+      +-----------+
-
-attrib_t::normals => 3 floats per vertex
-
-       n[0]        n[1]        n[2]        n[3]               n[n-1]
-  +-----------+-----------+-----------+-----------+      +-----------+
-  | x | y | z | x | y | z | x | y | z | x | y | z | .... | x | y | z |
-  +-----------+-----------+-----------+-----------+      +-----------+
-
-attrib_t::texcoords => 2 floats per vertex
-
-       t[0]        t[1]        t[2]        t[3]               t[n-1]
-  +-----------+-----------+-----------+-----------+      +-----------+
-  |  u  |  v  |  u  |  v  |  u  |  v  |  u  |  v  | .... |  u  |  v  |
-  +-----------+-----------+-----------+-----------+      +-----------+
-
-```
-
-Each `shape_t::mesh_t` does not contain vertex data but contains array index to `attrib_t`.
-See `loader_example.cc` for more details.
-
-
-```
-
-mesh_t::indices => array of vertex indices.
-
-  +----+----+----+----+----+----+----+----+----+----+     +--------+
-  | i0 | i1 | i2 | i3 | i4 | i5 | i6 | i7 | i8 | i9 | ... | i(n-1) |
-  +----+----+----+----+----+----+----+----+----+----+     +--------+
-
-Each index has an array index to attrib_t::vertices, attrib_t::normals and attrib_t::texcoords.
-
-mesh_t::num_face_vertices => array of the number of vertices per face(e.g. 3 = triangle, 4 = quad , 5 or more = N-gons).

-```
-
-Note that when `triangulate` flas is true in `tinyobj::LoadObj()` argument, `num_face_vertices` are all filled with 3(triangle).

-## Optimized loader
-
-Optimized multi-threaded .obj loader is available at `experimental/` directory.
-If you want absolute performance to load .obj data, this optimized loader will fit your purpose.
-Note that the optimized loader uses C++11 thread and it does less error checks but may work most .obj data.
-
-Here is some benchmark result. Time are measured on MacBook 12(Early 2016, Core m5 1.2GHz).
-
-* Rungholt scene(6M triangles)
-  * old version(v0.9.x): 15500 msecs.
-  * baseline(v1.0.x): 6800 msecs(2.3x faster than old version)
-  * optimised: 1500 msecs(10x faster than old version, 4.5x faster than baseline)
-
-
-## Tests
-
-Unit tests are provided in `tests` directory. See `tests/README.md` for details.

+"""Console-entry shims for the bundled C++ executables.
+
+The wheel ships ``renderapp`` and ``renderbatch`` inside
+``<site-packages>/ovrpy/bin/`` (see ``apps/CMakeLists.txt``). Putting the
+binaries directly on ``$PATH`` from there would require an
+``INSTALL_RPATH`` that crosses the bin/ <-> site-packages/ovrpy/
+boundary - brittle because the relative path depends on the Python
+version (``python3.11``, ``python3.12``, ...).
+
+Instead, ``[project.scripts]`` in ``pyproject.toml`` maps the console
+names to the shim functions below; pip emits a tiny Python launcher in
+``<env>/bin/`` that calls our shim, which in turn ``os.execv``s the real
+binary. The binary's own ``INSTALL_RPATH=$ORIGIN/..`` then resolves
+``librenderlib.so`` + the rest of the closure as siblings inside the
+package, with no Python-version-specific paths involved.
+
+We anchor the lookup on ``_core.__file__`` rather than ``__file__``
+because under an editable install (``pip install -e .`` /
+``uv sync --extra test``), this module's ``__file__`` resolves to the
+*source* tree (``<repo>/python/ovrpy/_apps.py``), while the binaries
+live next to the *installed* extension. ``_core.__file__`` always points

+so this helper is safe to use for both backends.

+# OVR Test Suite
+
+This directory contains the unified test suite for OVR: C++/CUDA unit
+tests (doctest), Python binding tests (pytest), and rendering regression
+tests (golden-image PSNR + SSIM). Everything is driven through **CTest**
+so a single command runs the lot.
+
+User-facing install/run instructions live in [`../README.md`](../README.md);
+build-system internals (CMake options, scikit-build-core wheel layout,
+component scoping, loader-error helper) are in [`../DEV.md`](../DEV.md).
+
+## Requirements
+
+`OVR_BUILD_TESTS=ON` enforces these at configure time — any missing piece
+is a hard `FATAL_ERROR` (no silent skips):
+
+* a Python 3 interpreter (`find_package(Python3 ... REQUIRED)`)
+* `pytest` importable from that interpreter (probed via `python3 -c "import pytest"`)
+* `OVR_BUILD_PYTHON_BINDINGS=ON` and the `_core` (a.k.a. `ovrpy._core`) target
+
+Install the Python deps once before configuring. Either path works:
+
+```bash
+# (a) editable install of the ovrpy package; also pulls test extras
+python3 -m pip install -e .[test]
+
+# (b) bare deps only (skips the scikit-build-core build step; useful in
+#     CI where cmake is invoked separately)
+python3 -m pip install pytest pytest-xdist pytest-cov numpy pillow scikit-image
+```
+
+(Use a virtualenv if your system Python is managed; on Debian/Ubuntu
+`pip install` may otherwise refuse with PEP 668.)
+
+## Quick start
+
+```bash
+# 1. Configure with tests enabled (requires the deps above)
+cmake -S . -B build -DOVR_BUILD_TESTS=ON -DOVR_BUILD_PYTHON_BINDINGS=ON
+
+# 2. Build (doctest is fetched by FetchContent during this step)
+cmake --build build -j
+
+# 3. Run the whole suite
+ctest --test-dir build --output-on-failure
+
+# 3b. CPU-only run (skip GPU-gated tests)
+ctest --test-dir build --output-on-failure -LE gpu
+```
+
+Or, from the top-level helper script. The script never installs anything
+on your behalf: when `--test` / `--all` is used and `pytest` isn't
+importable, it prints the exact `pip install` command and exits so you
+can run it yourself (in a venv, conda env, or with whatever package
+manager fits your setup).
+
+```bash
+./scripts/build.sh --all     # configure + build + test
+./scripts/build.sh --test    # test only (assumes build is up to date)
+```
+
+Same applies to git submodules: the script checks `git submodule status`
+and exits with the manual `git submodule update --init --recursive`
+command if anything is uninitialised, rather than fetching submodules
+behind your back.
+

+
+## CTest labels
+
+Every test carries one or more labels so you can slice the run:
+
+| Label        | Meaning                                               |
+| ------------ | ----------------------------------------------------- |
+| `cpp`        | C++ doctest case (CPU-only unless also `gpu`)         |
+| `gpu`        | Needs a CUDA device; skipped when `gpu_probe` fails   |
+| `python`     | The `pytest` entry that runs every Python test module |
+| `gpu_probe`  | The cheap probe that enables/disables the `gpu` label |
+
+Examples:
+
+```bash
+ctest -L cpp              # only C++ unit tests
+ctest -L gpu              # only GPU tests
+ctest -LE gpu             # everything except GPU tests (CI default)
+ctest -R python_tests     # just the Python suite
+```
+
+## Python-specific markers
+
+The pytest suite is sliced by hardware tier and by cost. Markers are
+registered in `pyproject.toml` (`[tool.pytest.ini_options]`) and
+`--strict-markers` is on, so typos error
+out instead of silently selecting nothing.
+
+| Marker | Applied to | Use |
+| --- | --- | --- |
+| `gpu` | `[optix7]` parametrize variants (via `pytest.param("optix7", marks=...)` in `conftest.py`) | `pytest -m "not gpu"` to skip GPU-bound tests on a CPU-only host |
+| `cpu` | `[ospray]` parametrize variants | `pytest -m "not cpu"` to run only the GPU tier |
+| `slow` | path-tracing tests (`@pytest.mark.slow`) | `pytest -m "not slow"` for a fast inner loop |
+| `golden` | rendering regression tests | `pytest -m golden` to run only the baseline checks |
+
+```bash
+pytest -m "not gpu"        # CPU-only run (matches `ctest -LE gpu`)
+pytest -m "not cpu"        # GPU-only run
+pytest -m "not slow"       # skip the expensive path-tracing tests
+pytest -m golden           # only the rendering regression tests
+```
+
+Nothing is skipped automatically — running `pytest tests/python/` with
+no `-m` filter attempts every variant and any missing/broken hardware
+surfaces as a real failure.
+
+## Golden-image regression workflow
+
+The rendering regression tests in `python/test_rendering_regression.py`
+compare a freshly-rendered image against a committed baseline.
+
+* **First time on a new backend or after an intentional render change:**
+
+  ```bash
+  pytest tests/python/test_rendering_regression.py --update-baselines
+  git add tests/fixtures/golden/<backend>/*.png
+  git commit -m "Regenerate rendering baselines"
+  ```
+
+* **CI failures** upload an `actual.png` + `diff.png` artifact per
+  failing test; download from the run's Artifacts tab to debug.
+
+* **Tolerances** live in `TOLERANCES` at the top of
+  `test_rendering_regression.py` and are currently `PSNR >= 30 dB` and
+  `SSIM >= 0.90`. Bump them (tighter) once baselines stabilise on your
+  reference machine.
+
+## CUDA / GPU gating
+
+The C++/CUDA tests (`tests/cpp/`) and the Python tests (`tests/python/`)
+gate GPU dependence differently:
+
+* **C++ tier (CTest)**: doctest binaries labelled `gpu` declare a
+  `FIXTURES_REQUIRED gpu_available` dependency. The `gpu_available`
+  fixture is set up by a small `gpu_probe` executable (built when
+  `OVR_BUILD_TESTS=ON` and CUDA is enabled) that exits non-zero when
+  `cudaGetDeviceCount() <= 0`. CTest then auto-skips dependent tests on
+  GPU-less hosts — no manual flag needed. `ctest -LE gpu` is also
+  available as an explicit opt-out.
+* **Python tier (pytest)**: nothing auto-skips. The `[optix7]`
+  parametrize variants are tagged with the `gpu` marker (see the table
+  above); the user opts out explicitly with `pytest -m "not gpu"` (or
+  `ctest -LE gpu`, which is what the CI uses).
+
+## Coverage
+
+With `-DOVR_ENABLE_COVERAGE=ON -DCMAKE_BUILD_TYPE=Debug`, two commands
+produce a combined report:
+
+```bash
+cmake -S . -B build -DCMAKE_BUILD_TYPE=Debug -DOVR_BUILD_TESTS=ON \
+      -DOVR_BUILD_PYTHON_BINDINGS=ON -DOVR_ENABLE_COVERAGE=ON
+cmake --build build -j
+
+# Run tests + generate XML/HTML reports
+cmake --build build --target coverage
+# Output: build/coverage/coverage.xml  (C++, Cobertura XML)
+#         build/coverage/index.html    (C++, drill-down HTML)
+#         build/coverage/coverage-py.xml (Python, if pytest-cov installed)
+```
+
+`gcovr` is the only external tool required; `pip install gcovr`.
+
+## Synthetic volume fixture
+
+Because the committed `test_scene.json` references an absolute data path
+that only exists on the original author's machine, we also generate a
+self-contained 32³ gaussian blob as part of the build
+(`tests/generate_synthetic_volume.cmake`). It ends up at
+`build/tests/generated_fixtures/synthetic_scene.json` and is what the
+Python suite picks up by default through the `scene_path` fixture.
+
+## Troubleshooting
+
+* **`ModuleNotFoundError: No module named 'ovrpy'`**  
+  Either the build dir is not on `sys.path` or you haven't installed the
+  package. Pick one:
+    * Run tests via `ctest` (CTest sets `OVR_BUILD_DIR` to the build dir,
+      and the staged `<build>/ovrpy/` package lives directly under it).
+    * Export `OVR_BUILD_DIR=<path-to-build>` before invoking pytest.
+    * Run `pip install -e .` from the repo root so `ovrpy` lands in
+      site-packages.
+
+* **`ImportError: libospray...so`**  
+  Load the runtime env first:  `source scripts/run.sh`.
+
+* **`no CUDA device`** during `doctest_discover_tests`  
+  GPU tests are discovered via `DISCOVERY_MODE PRE_TEST` and will only
+  try to enumerate at ctest-time, not at build-time. If you see this at
+  build-time, your CMake may be older than 3.18 — bump it.
