I started to produce some code for a feature plot, but got bogged down
in graphics and have been waiting for the new graphics libraries to
appear before continuing.
If anyone wants to look at what I have already, I can mail it to them.
I would like it to output a graphics image and a file that could be used
as an HTML client-side or server-side image active area map.
