And also GRASS_LINE_WIDTH. And maybe GRASS_FRAME=t,b,l,r. But not text
rotation.

And then change all of these environment variables into GRASS
variables, and provide a d.config program to set/get them.

R_font(), R_text_size(), R_line_width() etc would still exist, but
would only change the settings for the current process, not
persistently.

We probably also want a global scale setting, which would affect
various dimensions which are currently hard-coded, e.g. the size of
axis ticks, etc.
