it's not my area (I'm troll), but if I understand correctly - You are refering 
to diferent symbols drawn on map (display). 
Using fonts to show various symbols is easyest and common used trick (look ar 
ArcView), but it has drawbacks - user has to create new font to get own 
symbols for displaying and that's not good. In ArcView I also have run into 
different problems coming from font usage as symbol.
Having all code already in GRASS is good, but I would better see as GRASS 7 
wish SVG vector symbol support. QGIS already to that way - You can draw image 
in any vector image manipulation soft (Inkscape, CorelDraw etc.) and just 
show in right place. Size, rotation is not a problem.
Pros: Scalable ;) , color, easy to add own symbols.
Cons: adds another dependency for GRASS.

Just my 0.02,
