Unfortunately, that doesn't help, even after I adjust the scale and translate
the sphere such that it goes from y=0 to y=1, as required by map_type 2. The
distortions are still present.
Yes, I am not entirely sure that this is the case. My Mathematica implementation
of the conversion may be faulty (even though I followed mathworld [1]), is there
a standard way to deal with this? Some UNIX tool or even a built-in feature of
povray?
