Gregor Schneider 2bb3d73470 Evgeny Boltik <BSTSoft AT narod DOT ru>:
Generic StretchBlt implementation for all bitrates with partial ROP and clipping support, see bug #4075.
Some changes from me applied to the patch:
- ROP variables renamed, applied consistent indentation, abort operation if pattern ROP and dprint once, split src and dst dprints
- Access source surface only if source is actually used, fixes mem access crashes
- Offer external drivers a NULL surface ptr if source is not used, since they (VMWare for example) access it although they shouldn't (another crash)
- Fixes bug #2609, support for pattern ROPs will be added after some restructuring
- Clipping still has some issues (bugs 3325, 3477, 4089) which seem to be related to IntEng- and EngStretchBlt
