The isoblob isn't as capable at solving for intersections as a regular
isosurface--and it also is unable to use method 2, which is a distinct
disadvantage, since it means that pigments won't work correctly because
of their lack of an interval solving method. (I don't understand the
method 2 code yet. It'll take a while to figure that one out.) The best
thing to do for now is to turn on aa and let it take care of the black
spots by finding correct intersections nearby.

BTW, I'd like to see the new isosurface files if possible; an addition
of r, theta, and phi will likely force some modifications to my
function-normal code.
