  If the trace level was not limited then reflecting/refracting objects
could cause an infinite loop. That's the main reason why the trace level
is limited.
  However, objects which do not reflect nor refract cannot cause an infinite
loop.

  But perhaps it might be a good idea to be able to limit the number of
transparent objects traced, if needed...
