A rapid render with the scene scaled up by 100 shows that all artifacts
disappear.
I rmember now that the discussion about the epsilon was (amongst other I
suppose) around the "Ringworld" scenes back in October/November 2005. There
was even a POV-Ray patch provided (By David Buck:
<4365fcf9$1@news.povray.org>) that corrected the epsilon value for those
scenes combining very distant and very near objects.
I totally forgot about this while I felt something scratching at the back of
my mind :-) Thank you again for reminding me!!
