[GRASS5] Circle in d.rast.arrow

[Vidya Kotamraju]

Hi all,
I am making a slight modification to d.rast.arrow in order to suit our 
mapping needs.
The original program draws arrows in 8 possible directions for each cell 
value of the raster map.
I need to replace one of the arrows (say arrow_n ie arrow for north) with a 
circle.
Is there already similar code written for the same or maybe a code in some 
other module that i could modify?

Thanx in advance,
Vidya Kotamraju.
