Most design problems are due to my coding inefficiency.

Yes, the bug that was introduced to the final release of 3.5.

I had forgotten that I'd left that code there.

My first draft had the macro proceed stepwise from say 0 to 360 or 0 to 180,
(for theta or phi).  Then I tried an artistic effect where I would have the
top of something be more spherical and less faceted and the bottom be more
faceted: hence a nonlinear stepwise increase in the angle.   And to do so, I
was forced to use pow(_AnyExpression_, 2) .   In going back to a linear
system, I just replaced the 2 with a 1 but forgot to delete the pow.

I would certainly not be offended it you rewrote this utility to be more
elegant and efficient.

Thanks for the consideration..............
