+ * ----------------------------
+ *  < 64	PolicyMono
+ *  < 256	PolicyGray
+ *  256		PolicyColor (only on PseudoColor)
+ *
+ * The actual allocation code lives in miindex.c, and so is
+ * austensibly server dependent, but that code does:
+ *
+ * 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)
+ *
+ * Here's a picture to help understand how many colors are
+ * actually allocated (this is just the gray ramp):
+ *
+ *                 gray level
+ * all   0000 1555 2aaa 4000 5555 6aaa 8000 9555 aaaa bfff d555 eaaa ffff

+ * extra      1555 2aaa 4000      6aaa 8000 9555      bfff d555 eaaa
+ *
+ * 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
