> BKD polygon queries should avoid per-hit filtering when cell is fully enclosed

> 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.
