[gschneider] 44712: [win32k] - Add support for DIBINDEX, PALETTERGB, PALETTEINDEX macros in SetPixel(V) - Before it did just take every COLORREF as a RGB color, while it could also mean (dib-)palette indices - Fixes several gdi32 bitmap winetests (depending on bit depth between 2 and ~500), 2 palette tests and some palette drawing issues - One problem with palette indices remains in true color bit modes (see bitmap test)

[win32k]
- Add support for DIBINDEX, PALETTERGB, PALETTEINDEX macros in SetPixel(V)
- Before it did just take every COLORREF as a RGB color, while it could also mean (dib-)palette indices
- Fixes several gdi32 bitmap winetests (depending on bit depth between 2 and ~500), 2 palette tests and some palette drawing issues
- One problem with palette indices remains in true color bit modes (see bitmap test)
