I didn't try that - yet - but I finally got around the problems I had
with the original POV-Ray objects though. I tried SOR and the STURM root
solving obtion and there still where some fuzzy features in the image.
FInally I got it to work using bicubic LATHE and STURM ...
Perhaps there should be a warning sign in the online documentation of
the SOR object:
"Using this object might or will result in unwanted pixels in your scene
and unpredictable results. Use LATHE instead!"
