RLE bitmaps are not decoded properly

[PluMGMK]

Same game I referred to on my website a few years ago… The toolbar has some buttons which I believe use monochrome bitmaps to indicate their functions. However, when playing using this driver, the buttons render with random colour bitmaps instead. Presumably a mono/colour check is broken somewhere in the driver…

This screenshot taken on v0.1.1 illustrates the issue:

The option buttons to the right also demonstrate #12, and the artefacts to the left of the flag icon, and of the minimize button in the titlebar, demonstrate #5.

For reference, here's how it looks with the standard VGA driver:

Looks like these icons are 4-bit RLE bitmaps, and I haven't touched the RLE code in this driver since starting from the V7VGA baseline, so this probably explains the garbage – renaming issue accordingly…
