[DIBLIB]

Browse Source 
- Implement spacial even more optimized versions of SRCCOPY on equal surfaces for 8,16,24 and 32bpp.
- Add the right-to-left versions to the function tables
- Add _CALCSHIFT macro(s) to calculate the shift in the dib functions, instead of precalculating it in EngBitBlt. This costs us a few bytes per function (yes, with so many functions, every byte counts!) but since it's only for 1 and 4 bpp and improves the code by keeping DIB specific code out of the Eng function, it's reasonable to do so.
- Add optional optimization pragmas
