Glynn,
I’m thinking about making a convenience default setting dialog for GRASS in the wxPython GUI. It would simply let users select a TT font (Do I need to have an option for a stroke font too?). This font would then be set at render time using the GRASS_FONT environmental variable.
Is there any way to set the size for the font (e.g., for legends and scalebars where you can’t select a size)? Or is it just a font name?

It would be wise to allow stroke fonts to be selected, as they will
always be available. The set of available stroke fonts can be obtained
by listing $GISBASE/fonts/*.hmp.
This font would then be set at
render time using the GRASS_FONT environmental variable.
With FreeType fonts, you also want to set GRASS_FT_ENCODING. If this
isn't set, it defaults to ISO-8859-1 (this is hard-coded if built
without iconv).
Unless Python provides a better way, you may be able to get the
locale's encoding[1] using the command "locale charmap".
[1] I'm presuming that's what Python uses when passing strings to the
child's argv or stdin.

No, modules have to set the text size themselves. It is initially zero
(and, with a standalone driver, persists between clients), so modules
which draw text always set it explicitly (whether from an option, a
calculation based upon the amount of text being drawn and the size of
the screen, or a hard-coded constant).
