Thanks jr (and Jerome)!

I see it too in all my recent povr versions. It was OK in versions early 
this year, so something I've done between then and early July.

I'll do a binary search - compile/run through my commits to find the 
commit causing the problem. FYI. No photons required to see it.

(jr, If you are looking for a scene with a parabolic mirror I recall 
Warp doing one some years ago which he posted. I thought had a copy 
somewhere, but I cannot find it at the moment. He might have used a 
polynomial for the shape.)
