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.
