Ah, then if I raise max_trace_level, I should raise max_intersections as
well? Or is this related to something entirely different?

Do I understand correctly that the "intersection-count" gets incremented
everytime the viewing-ray hits an object? Does it get incremented by two
when the ray gets split into reflective and refractive ray? If I'm getting
too technical, then sorry for the nuisance, but I've always been interested
in how POV-Ray's clockwork looks.

Tim
