Hoss Man updated LUCENE-7239:
-----------------------------
Fix Version/s: (was: 6.0)
master (7.0)
Manually correcting fixVersion per Step #S5 of LUCENE-7271
FWIW: This issue has no commits linked in comments, so I'm only assuming
"fix=6.0" should be replaced with "fix=master" based on the timeframe the issue
was created/resolved in.

> Project: Lucene - Core

> This is inspired by the "reliability and numerical stability" recommendations
> at the end of http://www-ma2.upc.es/geoc/Schirra-pointPolygon.pdf.
> Basically our polys need to answer two questions that are slow today:
> contains(point)
> crosses(rectangle)
> Both of these ops only care about a subset of edges: the ones overlapping a y
> interval range. We can organize these edges in an interval tree to be
> practical and speed things up a lot. Worst case is still O(n) but those
> solutions are more complex to do.
