The default of "Helvetica" seems to cause a lot of trouble. For
example, many people report problems when trying to generate png files
with gnuplot. I only chose "Helvetica" because that's the default in
Matlab and I thought people would expect that. But since it causes so
much trouble, maybe we should switch it to "*", which in Octave means
"use the default font". If the gnuplot backend sees "*" for the font
name, it just skips trying to set an explicit name and gnuplot uses
its default. Does anyone see a good reason not to make this change?
Thanks,
