Yes, it is a hack.  Offhand, I can't think of a way to do the right thing
with respect to effectively infinite intervals, but I'll sleep on it.  
Suggestions are welcome, of course.  One idea I'm bouncing around is 
the notion that rays leaving the bounding sphere of the scene should be
split into intervals at the point where they leave the sphere, but I'm 
not sure what implications that would have.
