I added some hard-earned tips about how to use the new 24-bit Z-buffer to
my existing web page about creating graphics on systems without display
hardware
http://idl.tamu.edu/headless_X.html
In almost all cases the Z-buffer should be easier to use than Xvfb,
and I expect to switch to it for most of my scripted graphics.
