Hmm. Any BDF/PCF fonts are usable in your GTK2 application?
All BDF/PCF fonts are ignored (and fallback to other fonts)?

Umm, I have no idea. I'm afraid that Pango has no backends
that works with specific application, and no way to pass
application specific informations to backends. Furthermore,
I'm afraid that it's difficult (or impossible?) to bind
suitable backend per applications (e.g. Mozilla uses Cairo
backend, GAIM uses XFT backend, etc etc). So, if someone
wants to show application-specific font in the font menu of
his application, he may have to write font menu widget from
scratch, without pango, without font-config.

Umm, It makes me afraid about the font can cause problems
when it's accessed via Unicodized libraries, like font-config,
XFT and Pango.
