You lost me there. How could you not know which is which if they already
go in the opposite direction? Just take a cross product at the topmost
point. If it’s negative, then it’s clockwise and thus a hole.

I mostly meant that I knew what their windings had to be (because of the way the
edges are constructed), but the code isn’t aware of it. However, like you say,
it’s easy enough to find an extreme point and test the winding.
