Karl Wright commented on LUCENE-8281:
-------------------------------------
I have a good way to test for whether an Edge's XYZBounds are correct.
Basically, I will add debug code at the construction of the iterator that will
go over ALL Edge objects and look for intersections within bounds, and print
those. Then we can compare what we should see with what we actually do. If
there is a difference, then that would mean incorrectly computed XYZBounds for
a specific edge, and I can drill into that further.
