+ * 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.
