New Revision: 33418
URL: http://svn.reactos.org/svn/reactos?rev=33418&view=rev
Log:
- Get rid of duplicated (and different) NB_LAST_STOCK definitions in gdi32 and win32k, now it's defined to 22 (19 being a last public stock object, other 2 are internal).
- Move a DEFAULT_BITMAP definiton from gdi32 into ntgdityp.h (not the best place, but could be moved to a better one later), and assign it a number 21, which it is on Windows XP (tested with a win32kntest framework, tests are committed).
- Fix CreateBitmap to return a 1x1 stock bitmap object if the requested Width and Height are 0.
- All of this work is based on Magnus Olsen's patches and Wine.
