OHHHHhhhhhh, so much debugging.
Still a little glitch to work out, but it's super close.

I think this should be trivial in comparison.  :D


So - here's a coil wrapping around a torus 5 times.   Super easy as a sphere
weep and parametric or isosurface or polynomial...   but if the torus is
deformed...

With the bicubic_patch system, everything follows the surface of the torus.
Apologies for my complete lack of artistic talent on short notice.
It's a proof-of-concept WIP.
