Karl Wright updated LUCENE-6487:
--------------------------------
Attachment: LUCENE-6487.patch
Fixing all remaining bugs and adding a random test for WGS84 model as well.
Note that I had to give up on having an ellipsoid with different scaling
factors for x and y. This is because a "latitude slice" is not actually a
slice on such worlds, and therefore GeoBBox's don't actually work.
There is one more change I'd like to explore having to do with consistent
determination of GeoPath width. After that I will try to get someone's
attention so this can be committed.

> WGS84 compatibility has been requested for geo3d. This involves working with
> an ellipsoid rather than a unit sphere. The general formula for an ellipsoid
> is:
> x^2/a^2 + y^2/b^2 + z^2/c^2 = 1
