New Revision: 50613
URL: http://svn.reactos.org/svn/reactos?rev=50613&view=rev
Log:
- Implement support for smoothed (gray) glyph rendering.
- Modify GreTextOut to use sharp rendering for non-antialised glyphs and smooth for AA
ones respectively.
- Removed unnecessary unused code from font.c.
- This fixes bug 5327 if FontSmoothing is enabled in the registry.
