After a bit more reading it appears that I have indeed misunderstood
how ForceRHR() should work with interior rings.  They're supposed
to be ordered in the opposite direction as the exterior ring,
correct?  The right-hand rule applied to polygons means the exterior
ring is counter-clockwise and the interior rings are clockwise --
is that right?  Or am I still confused?
