This is actually almost trivial, since the clipping planes are stored
in the view setting. Okay, it may not seem trivial if you lack
experience with the Pymol/POVRay communication, and with POVRay
macros. Unfortunately I don't have time now or the coming two weeks,
but I'll try and put it into an easily accessible form soon. Maybe to
Wiki is the right place to expand on this.

For those interested, I'll add this to my pymolmacro.inc POVRay
include file, which should be in the archives somewhere.

Cheers,

Tsjerk
