- * PolicyMono	    Allocate no additional colors, use black and white

- * PolicyGray	    Allocate 13 gray levels (11 cells used)

- * PolicyColor	    Allocate a 4x4x4 cube and 13 gray levels (71 cells used)

- * PolicyAll	    Allocate as big a cube as possible, fill with gray (all)

- *

- * The default colormap supplies two gray levels (black/white), the

- * 4x4x4 cube allocates another two and nine more are allocated to fill

- * in the 13 levels.  When the 4x4x4 cube is not allocated, a total of
