Actually, the answer is:  do nothing.

If we were importing/converting the DATA from one system to the other, then we
would need to change the vector components to reflect this and make everything
work properly.

When we're using the RH data in the RH coordinate space, or using the LH data in
the LH coordinate space, the code and vector functions remain unchanged.

(As mentioned in another thread, things got derailed when I had R instead of r,
so the normals were pointing every which way, and my isosurface wasn't behaving
properly either, so that just added to the confusion.)
