Well here's the thing.   the scene was rendering just fine for several renders
before I made a radical change to the functions (just adding a scalar), and then
even when i changed everything back to the original functions - the weird
behaviour persisted.

I'm not redefining any apparent keywords, however I am using the image
dimensions to adjust the aspect ratio in the user_defined block. Maybe I'll
define a right vector just to mix things up and see what happens.

In any event, the Cartesian forms are easy enough to implement, and calculating
the partial derivatives is 1000 times easier than in polar coordinates.
