Subject: [PATCH] [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)
