Applying the transformation in question has no effect on the winding
order. Rewrite that section.
While all the examples are correct, clarify the rules for the geometry
they use since the winding order varies. Fix up the triangle example code
to use front=CCW for clarity (even though it does not matter much since
culling is off there).
