It's either device coordinates or there is a round-off
problem.

Well, as you say, it is weird. Now that I think about
it, maybe because it *is* done in device coordinates.
I never thought of that before. It is "mostly" normal
for line and contour plots. It's mostly crazy for surfaces.
But, then again, it would be if it was doing the rotations
in device coordinates. 2.5D surfaces, rotated in 3D device
coordinate space...yes, that would be weird. :-)

I've never had much of a problem with plots, except
for this near-the-edge clipping thing going on.

Cheers,
