- Rewrite NtGdiGetDIBitsInternal, with WINE as a reference.
  - Get back DIB Section creation to classic BITMAPINFO.
This si the beginnig of the end for all this BITMAPV5INFO stuff.
It is horrible, BITMAPCOREINFO->BITMAPINFO is already made in user mode, and V4 and V5 features are not used so often.
