Things get stranger...
If you replace the clipped_by section with:
clipped_by {
plane { y, -1.0 }
}
....you end up with an empty ring partway along the shape in addition to the
previously-mentioned disappearing act above +1*y. (Compare with the same
scene rendered in 3.61a...)
As far as the comments, I can't seem to find quadrics.cpp anywhere...
