Log:
[WIN32K]
- Fix right-to-left support the new EngBitBlt code
- Remove an ASSERT that we don't support
- Fix clipping in IntEngBitBlt by bailing out when the target rect got empty
- Delete obsolete file
You can use the code now, but there is a bug in the clipping code somewhere, sometimes
causing the taskbar to be overwritten
