Remove the bespoke DPI plumbing (rocprofvis_view_set_dpi, GLFW content scale callback, SettingsManager DPI state, dpi_based_scaling setting, and FontManager::GetDPIScaledFontIndex) in favor of ImGui's built-in DPI font scaling (ConfigDpiScaleFonts/ConfigDpiScaleViewports + multi-viewport). The font size setting becomes a plain user-controlled slider clamped to a supported range, and fixed window sizes no longer multiply by a manual DPI factor. The status bar height now follows the current font size via a single guarded check that handles both user- and DPI-driven font changes. Co-authored-by: Cursor <cursoragent@cursor.com>
Collapse the verbose multi-line comments and remove the defensive static_assert block added with the DPI rework so the comments stay terse and consistent with the rest of the view layer. No behavior change. Co-authored-by: Cursor <cursoragent@cursor.com>

Remove the multi-viewport/windowing enablement (ViewportsEnable and the platform-window render pass) that main does not have, and revert the font-size slider redesign, font-range clamp, extra FontManager helpers, and incidental gui_helpers rewrite. The branch now only swaps the custom DPI handling for ImGui's built-in DPI font scaling (ConfigDpiScaleFonts), keeping the status bar sizing and banner scaling needed under it.

Replace the font-size dropdown with a slider (in points) bounded to a supported range, and clamp the saved index on load/apply. The upper bound keeps the UI font from growing too large under ImGui DPI font scaling. Co-authored-by: Cursor <cursoragent@cursor.com>

Detect the applied font size once per frame in FontManager::Update so both user-selected sizes and ImGui auto-DPI scaling notify every kFontSizeChanged subscriber, and revert AppWindow's private status-bar poll back to a normal subscription. Co-authored-by: Cursor <cursoragent@cursor.com>

Summary
Replaces the project's custom DPI handling with Dear ImGui's built-in (1.92+) per-monitor DPI font scaling, and turns the font-size preference into a simple user slider.
rocprofvis_view_set_dpi, the GLFWcontent_scale_callback/glfwSetWindowContentScaleCallbackwiring,SettingsManager::Get/SetDPI+m_display_dpi, thedpi_based_scalinguser setting (+ its JSON key), andFontManager::GetDPIScaledFontIndex.io.ConfigDpiScaleFonts/io.ConfigDpiScaleViewports, enables multi-viewport (ImGuiConfigFlags_ViewportsEnable) with theUpdatePlatformWindows()/RenderPlatformWindowsDefault()pump in the main loop, andstyle.FontScaleMain = 1.0f.SettingsPanel), clamped to a supported range; previously persisted indices are clamped on load for backward compatibility.* dpimultipliers on fixed window sizes (shutdown dialog, minimap popup) and makes the internal-build banner viewport/font-scale aware instead of usingio.DisplaySize.UpdateStatusBar(), covering both user-driven and DPI-driven font changes (ImGui auto-DPI resizes fonts without firingkFontSizeChanged).
