[GRASS-dev] Re: [GRASS-user] Freetype fonts in gis.m

[Michael Barton]

Maybe this is what you're all getting at, but it seems most logical to have
a 'default' font that could be set by d.font* (putting it into GISRC seems
logical too). And also having each d.* command that uses text have the
ability to optionally set a font for that command. If the font is not set,
it uses the default; if the font is set for a command, it overrides the
default.

There should be no need to rerun d.font* for each command.
