7.5. ColorModel.discretize(): Discretize an integer color parameter

This static method converts a color parameter in [0.0, 1.0] to a discrete integer in [0, MAX_PARAM]. Values outside the range are forced back into the range; this prevents potential unpleasantnesses such as a color parameter being rounded to hex 100 when it must be no more than hex FF.
