[PATCH] Add a GDI version of RealizePalette. The base version won't suffice anymore as it is not able to upload palette changes to the drawable in an efficient way for both GDI and GL. Further the LoadLocation code in RealizePalette isn't needed for the GDI version as in all cases it works on system memory.
