Hi all,
This implements direct FrameBuffer => Texture blits (used in DungeonSiege to
do the realistic shadowing of the main characters). This prevents one usage
of glReadPixels (and helps speed a little bit).
Changelog:
- implement FB => Texture blits
- fix compilation on non-recent glext.h systems
