Subject: Re: wherefore CGM? 

gplot itself is a system independent cgm interpreter, with the concepts
of output devices and controllers. Thus, if gplot has just an XLib output
device, it will draw into a window, but will not handle any events.
Gplotm is compiled and linked with a Motif-type controller and an XLib
output device; it should handle expose events correctly. There's also
a gplotxv, etc..
I started on a java implementation of the gplot cgm interpreter (I'm
the gplot author), and it doesn't look too difficult, but the java drawing
capabilities are a bit too limited for an elegant CGM implementation at
the moment. I hear that there's a new drawing package due from Sun, so I'm
waiting on that.
