Well, I have a habit of thinking about it like this:

So once it's "unrolled", then rotation in degrees becomes offset in translation.
pi radians would be 3.14.... scalar.
Not sure if that's how it's handled by POV-Ray internally, but that should be
easy to test and document the magnitude and direction of the shift.
