Yes, my current tree renders quite slowly. Interestingly, it gets slower the
more functions I add to it (regardless of the max_gradient value.)  I
suppose there's a good mathematical reason for that(?)

I haven't yet tried #declare-ing the tree and using it multiple times--to
see if the render time stays the same, or if it increases by the number of
trees. I don't think it would increase by a great deal. I have a vague
impression (based on different experiments that I've done over time) that
an isosurface is *somehow* converted to a triangle mesh during
rendering--but that's just a wild conjecture.  Anybody know the answer?
