- Changed DD_OK to D3D_OK in some places for consistency
- Cleaned up some compiler warnings present without DGA2
- Changed order for DirectDrawEnumerateExA to enumerate at least
what abilities are known rather than bailing on unsupported flags
- Added DirectDrawCreateEx stub
files/dirs for easier maintenance. Cleaned up structs and include
files. Reindented the code. Started the same for Direct3D. Driver
inclusion now done by using configure/Makefile/ELF constructor tricks.
