 * This module provides device gamut boundary functionality used to
 * locate the non-monotonic device boundary surface, enabling
 * fast and accurate PCS gamut boundary plotting as well (for CMYK)
 * as allowing the location of device boundary overlaps, so that they
 * can be eliminated. This also allows rapid K min/max finding,
 * and rapid smoothed K map creation.
