Ideally, it should be possible to set the font/encoding globally, for
a specific display, and for a specific command.

If want to allow the user to choose fonts from a list, you can list
the FreeType fonts with "d.font.freetype -l"[1], and the stroke fonts
by enumerating the $GISBASE/fonts directory. Also, $GRASS_FONT can be
the absolute path to a .ttf file, so a "Browse" option might be
useful.

[1] With the -l switch, d.font.freetype never gets as far as calling
R_open_driver(), so it doesn't require a driver or for any of the
PNG-driver environment variables to be set
