This is a more general request for an overall beef-up
of the postscript device. As of 0.9pre, ps plots do not
appear to support use of !P.font to use native PS
fonts, device,/color doesn't work, every postscript
plot appears to have an empty page preceding it,
/isotropic doesn't seem to work, many characters come
out funny (like "^" or "_") etc. etc.
I don't know what other people do with idl/gdl but the
ability to generate publication-quality plots that can
be included in a paper strikes me as an important part
of the reason to use this software in the first place.
Let me take the opportunity to extend a heartfelt
thanks to the developers -- this is easily the most
important project I've seen on SF in ages...
