a good point.  as Paul said, PyDL was developed in <4 weeks as proof of
concept for a physics department presentation.  This precluded any sort of
DIY interfaces to existing C plotting libraries.  I would like to move over
to a free alternative, and have been reccommended to use a GTK option.
I'll look at this more after I submit my thesis in 8 weeks.

I don't think this always applies.  If you move to any sort of large
industry with in-house processing software, you'll probably be using that.
I went to the SSEC, I used IDL.  I go somewhere else, I'll use whatever
they use there to take advantage of the existing code-base.
