	I am currently trying to extend my 8-plane color X windows
driver to work on a 24-bit Iris/4D, but am somewhat confused as to
the correct way to go about this. I've read through all X11 colormap
tutorials we have online (ICCCM turorial, Xlib manual, several talks
given at USENIX, etc) but most deal do not talk about DirectColor
displays with 24 planes. I believe the ICCCM tutorial had a small
example showing how to allocate a 24-bit colormap using XAllocColorPlanes(),
but they did not show much else. Anyone have any code fragments they
wouldn't mind sharing that shows how to write to such a display?
