Robert Muir commented on LUCENE-7157:
-------------------------------------
Karl: i also would like to know if we solve your problem by refining docs to
say: outer rings should be clockwise, holes counter-clockwise. It would be
great to enforce this as well, if we had a simple static method that could
check a Polygon[] and ensure everything is well-formed. We would have to fix
some tests.
Keep in mind i didn't introduce the docs that say either order is acceptable. I
merely moved methods around, and either works at the moment because of that.

> The LatLonPoint API implementation pays attention to the order of the points;
> "clockwise" means one side of the polygon boundary, and "counterclockwise"
> means the complement. We need to use that in Geo3DPoint and convert into
> whatever the underlying GeoPolygonFactory method requires.
