Good plug -- but we can't count on Display PostScript or NeWS being
available.  I was hoping for a better X only solution (until the X
imaging extension finally arrives).

PS. From the recent activity around here it looks as though there might
be interest in defining an official X PostScript extension that could
act as a common API to both Display PostScript and NeWS (and any other
display oriented PostScript that might be around) --- at least at the
PostScript in a window level.  I'm assuming that this isn't already
happening somewhere.

PPS. I'm not volunteering to do anything.
