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

* policy depends on the size of the colormap:
|
|
*
|
|
* 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.
