- * 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.
