I have an indirect way of producing "unlimited"
size images of grasp surface and that is to
rewrite the grasp file as input for a raytracer
such as Povray. The surface can then be rendered
and output as an RGB image (MUCH smaller than a 
ps file !).

I use our Molecular Graphics program PREPI
( http://www.icnet.uk/bmm/PREPI) to read  
the grasp surface, set transparency etc and then
output for Povray.

If this program is of anyuse to you let 
me know and I can send you download details.
