Not to nitpick (I'm sure the Z-buffer works, though the comment
about fonts gives me pause), but I've had perfectly fine results using
the X driver and the following..

window, /pixmap ; Create a new graphics window as a pixmap

(etc., including TVRD, TVLCT, WRITE_GIF)

Any comments on the difference between a X pixmap and a Z-buffer? I
guess if you are running a remote X-terminal it may matter. Also,
given the clunkiness of various X servers (like Sun's), maybe having
IDL do the memory management is better.
