what are the CMKY to RGBA transform equations used in Cocoa?
I think Mac OS X uses ColorSync pervasively for this kind of stuff,
because it's very heavily optimized for both speed and accuracy.
If it is using ColorSync, it's probably doing everything via ICC
profiles, so I doubt you'll find out it's using the "one minus" method
or anything like that. There may be "fast paths," though, for
particular color spaces.
