Ignacio Vera commented on LUCENE-8133:
--------------------------------------
I understand that is clockwise when looking from the inside of the planet,
anyhow we have a common understanding.
I have a closer look to the problem and I think I understand what is going on.
When you look to the shortest edge and check if the points used to generate,
one of them is actually not within.
