On the home page of vpython.org, another improvement in povexport, the
module which lets you export a VPython scene as a POV-ray file, from
which POV-ray can make a high-quality ray-traced scene.
This correct an error in yesterday's posting in the axis of an elllipsoid.
It implements pyramid.
It gives color to the upcoming Visual 5 distant and local lights.
There is added documentation at the start of the module.
