In grass 6.2 check out the d.graph symbol command. There is scale and
rotate infrastructure there, although rotate isn't fully implimented.
d.vect and ps.map can also use these symbols, and ps.map does support
simple .eps icons as well (incl. rotation).
see D_symbol() and http://grass.gdf-hannover.de/wiki/IconSymbols
There is no .eps, .svg -> d.graph or symbol converter, but it would be
really great (and probably not that hard) for someone to write one. It's
been a long standing wish.
