Hi Severi,

this is a problem I've suffered from too. For some
extreme examples (and some hints) see in povray.general:

   Intersection with quartic: bug?   3 Sep. 2002
   Small is NOT BEAUTIFUL           11 Feb. 2003

The reason for this behavior are some 'Epsilon' values in the
Pov-Ray code which are neccessary (in this way some overlap is
created at corners to make them 'watertight', without such overlap
it would  sometimes be possible to look inside objects at corners
due to limited numerical precision), but these 'Epsilons' are a
little large.
