void HSV2RGB(hColor,rColor);
HSVColor *hColor; is the starting color record

RGBColor record.
hColor is the HSVColor record to be converted
rColor is the resulting, equivalent, RGBColor 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.
