Added Matrox Mystique emulation. This is a work in progress, and has a few known

issues :
- Only YUV supported for scaled ILOAD operations
- Several BLTMOD formats missing
- Bad texturing in Actua Soccer
- Flickering in Croc (broken vsync waiting?)
- Turok doesn't swap buffers correctly
- Some missing features
