I have a problem with lighting (I think) CGO lines, e.g.,
lineSet = [
> LINEWIDTH, 0.30,
> BEGIN, LINES,
> VECTOR, 0.0, 0.0, 0.0,
> VECTOR, 1.0, 1.0, 1.0,
> END,
> ]
> cmd.load_cgo( lineSet, 'LineSet' )
>
For some reason, lines appear crisp from one angle, and strangely distorted
from another angle (it's about 180deg for both -- think dark vs. light side
of the moon: there is a crossover point). Here are links to two screen shots
that show the problem:

I have tried respositioning the lights (in the screenshot they're at the 6
faces of the box, marked by blue balls), but it doesn't change the viewing
angle at all, only the shade of the lines. I have tried messing with the
specular and spec_direct settings, but that only caused the lines to
disappear completely (or rather, turn completely white). I also tried
changing the ambiance settings, but that only changed the hue of the lines.
I would really appreciate some help if anyone knows how to fix this. Thanks!
Oh, and for reference, here's my system information:
This Executable Build integrates and extends Open-Source PyMOL 1.3.
> OpenGL graphics engine:
> GL_VENDOR: NVIDIA Corporation
> GL_RENDERER: GeForce 9500 GT/PCI/SSE2
> GL_VERSION: 3.2.0 NVIDIA 195.36.24
> Detected 8 CPU cores. Enabled multithreaded rendering.

I recently went pack to 1.3 as I was getting __very__ slow load times with
1.4.
Cheers,
Stephen
