Is it possible to use something like "pnmalias" in g.pnmcomp to
anti-alias vector, text, and/or d.graph layers before/during the merge?
also in gis.m:
v.label does a really funky resize dance if launched from the
display labels controls (both PS and normal flavours).
can PS labels have transparency?
upon redraw with PS labels added but not populated you get:
error reading "file10": illegal operation on a directory

This can't be done here, as the incoming image is already aliased.
Antialiasing would have to go in the display drivers and it would need a way
to be controlled (turned on and off) on at least a per-module basis.
can PS labels have transparency?
My understanding is that this is being done on the tk canvas. None of tk
supports transparency beyond completely transparent/opaque.
AFAIK, there is no way to set a variable transparency for TclTk canvas text.

Hamish,

This seems to be happening in several modules now. Also, the options panels
are slow to come up. Has something changed in an underlying module for both
somewhere???
Cedrick, do you have any ideas??

...snip snip
I'll see if I can add some error checking for people who forget to fill in
the fields
