This latter idea would work much better with interaction with the TclTk GIS

The GIS Manager expects for each d.* command to create a single PPM/PGM
pair, whose name is based on the PID obtained at the start of the procedure
for each GIS layer. These are then inserted into g.pnmcomp at the end of the
stack of GIS layers.

d.vect.thematic is treated like any other d.* command. If it did it's own
compositing via g.pnmcomp, it would still be complicated to get this into
the normal GIS layer stack of PPM/PGM pairs because it is not easy to pass
file names from a bash script to a TclTk script (this an the issue with
legend creation).

This approach might make other interesting effects possible.
