AFAICT, :outline, :outlined, and :scalable all produce the same list of
fonts. It would help (me at least) if there was some guide to fc-list syntax
and options. The help is zen-like in its minimalism. Looking at the man page
for fontconfigure isn't much help either.

So, if you DO know the font face index, how do you specify it in GRASS_FONT?
