Alright. I both didn't remember well and I never completely understood 
what was happening... This is only a povr big jitter +j(>1.0) issue.

First jitter must be on. This is me not remembering - and, IIRC, it is 
on by default with recent POV-Ray releases, but not in povr.

Plus! The user value must be larger than 1.0 for the issue to show 
itself - which can only happen with my povr branch. The official release 
jitter can only be on or off. Somewhere the jitter value is getting 
reset/restored to 1.0 after each RTR frame - though in a quick look I 
don't see where!

I too continue to get AA in all my RTR frames, but povr's big jitter 
goes to a value of 1.0 after the first frame.

Thank you, Kenneth, for straightening me out! :-) I've added some notes 
to the source to jog my memory down the road...

Bill P.
