[jimtabor] 37784: - Moved SelectBitmap/Font to their proper places. - Correct CreateCompatibleBitmap issues, finding more bugs and noted them. - DibObj.c is a work in progress, needing more love. Managing SEH in a proper manner, fixing the SEH abuse. - Wine gdi bitmap cross tests looking better, 16 bpp down to 50 faults. - Need full spectrum testing, I exhausted my test suite so anything will do.

Log:
- Moved SelectBitmap/Font to their proper places.
- Correct CreateCompatibleBitmap issues, finding more bugs and noted them.
- DibObj.c is a work in progress, needing more love. Managing SEH in a proper manner,
fixing the SEH abuse.
- Wine gdi bitmap cross tests looking better, 16 bpp down to 50 faults.
- Need full spectrum testing, I exhausted my test suite so anything will do.
