RGB2CMY

Convert an RGB color record to its CMY equivalent

void RGB2CMY(rColor,cColor);

RGBColor *rColor; is the starting color record

CMYColor *cColor; is the resulting color record

The RGB2CMY procedure converts an RGBColor record to its equivalent

CMYColor record. CMY is the complement of RGB.

rColor is the RGBColor record to be converted

cColor is the resulting, equivalent, CMYColor record

Returns: none

Notes: A SmallFract is the fractional part of a Fixed number, can be assigned

directly to and from a short , and represents values between 0 and 65,535.

By using a SmallFract while short is used as an unsigned integer-sized

value (as is the case with RGBColor), the Color Picker sidesteps

problems with sign extensions in the conversion math.
