+ * For dynamic indexed visuals (GrayScale and PseudoColor), these control the

+ *
+ * Size Default Policy
+ * ----------------------------
+ * < 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
+ * b/w 0000 ffff
+ * 4x4x4 5555 aaaa
+ * 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
+ * 11 cells are allocated.
