HSL2RGB
HSL2RGB Convert an HSL color record to its RGB equivalent
#include <Picker.h> Color Picker Package
void HSL2RGB(hColor,rColor);
HSLColor *hColor; is the starting color record
RGBColor *rColor; is the resulting color record
The HSL2RGB procedure converts an HSLColor record to its equivalent
RGBColor record.
hColor is the HSLColor 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.
