With fc-cache I managed to create a file `fonts.cache-1'; but only
after copying the font source file `vice-cbm.bdf' to my fontdir
(/usr/local/lib/vice/fonts).  
The content is:
  "vice-cbm.bdf" 0 "VICE CBM:style=Regular:slant=0:weight=80:width=100:pixelsize=12:spacing=100:foundry=FreeType:antialias=False:index=0:outline=False:scalable=False:charset=:lang=:fontversion=0"

Now `VICE CBM' appears in the fontselector widget (vice-cbm.bdf gets
loaded; checked with strace) but choosing the font is not showing my CBM
font but probably default `Sans'.

I suspect that the .bdf font is not well behaving or my system lacks a
sprecial font rendering backend and therefore the font is ignored by
fontconfig & friends.

Are there any additional hints you can give? Of course I can send
`vice-cbm.bdf' if it is helpful to investigate the problem. Let me
know!

What's the best way to supply an application specific font? In my case
the font is special and not be useful for any other application. The
mapping is special (petscii and not ascii) and very specific symbolic
characters are supplied. However for the application it makes sense to
have this font (disk image preview, etc.).

In my GTK1 application the font is enabled from the special
application installation directory by:
[...]
    /* set X11 fontpath */
    if (access(PREFIX "/lib/vice/fonts/fonts.dir", R_OK) == 0)
    {
	const char *cmd = "xset fp+ " PREFIX "/lib/vice/fonts";
	
	if (system(cmd) != 0)
	    fprintf(stderr, _("Can't add fontpath `%s'.\n"), cmd);
	else
	    fprintf(stdout, _("Set fontpath: `%s'.\n"), cmd);
    }
[...]
at shutdown time the patch is removed again:
[...]
	/* remove fontpath, Don't care about result */
	system("xset fp- " PREFIX "/lib/vice/fonts");
[...]

`PREFIX' is the user supplied `--prefix' at configure time.

What would be the equivalent approach for GTK2 applications? 

Any further help is appreciated!
