The color of the pigment at each point is the color of the part of the 
scene seen through that point.

The headaches came from a misunderstanding of a POV function...and it 
works perfectly.

I doubt it...the syntax is just "portal_pigment {TYPE, PARAMETERS 
TRANSFORMS}", with the simplest syntax being "portal_pigment". You apply 
the pigment to the object, set the ambient to 1 if you don't want the 
pigment to be shaded, and transform the object and far end of the portal 
to the desired positions (unless you are using a camera portal), and 
that's it.
