Sorry, I should have been clearer (or, if your answer is complete, perhaps you
should ;).

Whilst internally POV can "see" that the shapes are infinite, at the trace-level
POV must give up at some distance, otherwise (afaics) any scene with an infinite
object might take forever to trace. I suppose another way of putting it is "what
bounding box does pov apply to infinite shapes?".
