That's a beautiful use of Dia.  Is it OK if we link to your page from the
Dia page (this will create some more traffic)?

There are fake X servers available, but running Dia without GTK would be
difficult at best.  For one thing, text widths are calculated by GDK
(though that can be done with FreeType now, but it asks X for font
information, too).  Hmmm... looks like I broke PNG export in CVS by adding
a dialog.  Gotta have a check for noninteractiveness.
