Bug in CMYK to RGB lookup table fixed, was broken since Feb 19th 2009.
The table is written as R,G,B values, but the color code was assuming
it was written as B,G,R (as are all RGB color values are stored in
AfterGRASP).

As part of figuring out this problem, all the RGB to CMYK and CMYK to RGB
conversion has been generalized and put in at a low level to apply to
all references to a Color value. This means that operations like
drawing into a CMYK image using RGB colors, and vis versa now work.
