[jira] [Updated] (LUCENE-6519) BKD polygon queries should avoid per-hit filtering when cell is fully enclosed

Patch, just pulling over code from LUCENE-6481 ... once that issue is done I'll refactor to share in GeoUtils.

> In LUCENE-6481, [~nknize] added methods to test for the relationship between an axis-aligned rect vs the query polygon, e.g. is the rect fully contained by the polygon, overlaps its boundaries, or fully outside the polygon.
> I think we should also use those methods to speed up BKDPointInPolygonQuery, to decide on recursively visiting the tree, how to handle the leaf blocks under internal nodes.
