The new algorithm only checks the contour with the largest area, which won’t catch a glyph with multiple outer contours whose smallest outer contour is counterclockwise. For example, consider a glyph for ⟨å⟩ where the base letter’s outer contour is fine but the ring’s is wrong.

@dscorbett Yes, we were debating that here.

This PR is likely going to end up getting deleted, as @simoncozens wants to revisit his previous version which was reporting false positives for some glyphs but otherwise tried to consider glyphs with several outer contours.

Thank you.

I think #4724 is a replacement.
