- when converting from a DDB to a DIB, the palette should be the same in the resulting DIB as the original DDB. This fixes the colour issue we had in the taskbar icons. (there's still a bit position problem as highlighted in the 1-4 bitmaps)
- Reformat the NtGdiGetDIBitsInternal code to a more readable state. *note, this function needs a considerable work. svn path=/trunk/; revision=29093
