Funny you should mention it...

dia-0.90/lib/font.c:
FontData font_data[] = {
  { "Times-Roman",
    "Times-Roman",
    { "-adobe-times-medium-r-normal-*-%d-*-*-*-*-*-*-*",
      NULL
    },
    "Times New Roman", "Regular"
  }, 
  { "Times-Italic",
.
.
.

The list includes the standard list of PostScript fonts, plus a few fonts
in other charsets that are also fairly common in those areas.  This is so
that we can do PostScript printing without embedding all chars as bitmaps
(for that is all you could get from an X font server).

There is in 0.90 experimental support for FreeType fonts, but it's by no
means perfect, and in particular assumes that you have the fonts locally
instead of through a font server.

In the CVS version, as you may see in the archives from a few weeks back,
we have changed to rely on Pango (GTK2) for our font listing, dynamically
adding fonts to the menu as the user selects them.  Much, much better.  But
then, Pango allows us to get the outlines we need to do PostScript
printing (which seems to be the next part up).
