Seems a common Xfont-->PostScript table could be built and if no map
exists, prod the user to either provide a PostScript equivalent or warn
them this'll increase the size of their .ps file dramatically.

So this means even if the font isn't a standard PostScript font, that you
can include the font as not too much a size increase on the .ps?

I guess I don't understand the Pango outline/postscript issues so much.
The main problem I consider myself having is to clear four dialogue boxes
about nonexistent fonts upon diagram load and the fact that all diagrams
always use Courier font despite the fact that the printout changes.

I assume you're saying these two issues disappear once CVS version becomes
Dia 0.95 or whatever the next version shall be?
