text size in the legend is determined by the legend's height.
 (or by the width for horizontal legends)
If you think the text is too big, make th legend a little shorter.
I tried to make the sizing pretty good by default - if you don't
like it you can always use "d.legend -c" to turn off the numbers
 (hey, that broke for FP maps in main.c rev2.5!)
and use d.text to place them.

d.font.freetype (optionally) and then d.text. You can also try
to use d.text.freetype and "d.title $MAP | d.text".

see the PNG driver help page or the d.out.file script for info on
writing graphics directly to a file.


ps - GRASS's xganim module is also interesting.
