Log:
- Win32k: DC_ATTR: Moved to it.
- We need to decide how to optimize the syncing. CreateD/IC/CompatibleDC, GetDCState and
SelectObject use the sync in one form. This can become ugly. Some DC handles do not belong
to the current process. We need to reorder the mess in dc.c and clean it up.
- Gdi32: The only ones using it are GetCurrentObject and with out updates
Get/SetDCBrush/PenColor.
- Implemented an example of RealizePalette. Moved SetBk/TextColor into dc.c, don't use
them.
- Update gdi32.def.
