[GRASS-dev] figureing out fonts - part 3 correction

[Michael Barton]

How does this work with d.barscale or d.text.

If a font isn't specified and GRASS_FONT is NOT set, it defaults to Romans.

If a font isn't specified and GRASS_FONT IS set, it defaults to GRASS_FONT.

If a font IS set, this overrides the other two.

Also, I forgot to reiterate that d.rast.nums only does Romans and does not
respond to GRASS_FONT.

Finally, helvetica is a very nice font for this stuff. How can ps.map
default to helvetica, however? Is it likely to be present on all systems?
What happens if it's missing?
