VTK (was Re: [Maxima] Maybe some work to make Maxima display much better)

There is a great deal to discuss about the future for interfaces for
Maxima. Indeed, part of what got me this far into Maxima was a project
I've been working on to provide a better user interface to Maxima. I'd
really rather focus on the basic text-mode of Maxima until at 6.0...

That said, I am interested in VTK. I'into the current mess I'm in is a
project I was working on in privateve seen some lovely 3D graphics from
VTK, but I can't find any examples of 2D plotting. Do you know of any? I
think solid 2D plotting is really my first concern.
