I've been following this thread and am becoming confuseder and confuseder.
I'm not new to GRASS and not new to X, but I'm new to GRASS with XDRIVER,
so maybe I've missed something. But I had the impression that GRASS (and
presumably XDRIVER) is coded for *24 bit* color in the first place -- I
set colors using 24-bit RGB frames. These frames wash out on my 8-bit
monitor, of course, but that doesn't seem to matter. Have I misconstrued
