>
> Currently a few remaining tests (around newRectQuery) are lenient and
> quantize the query rectangles. This is masking several bugs:
> 1. Both LatLonPoint and GeoPointField's bbox queries quantize their endpoints
> incorrectly at query-time, which can e.g. cause it to bring in false positive
> results
> 2. Tests have always been lenient about this (either by using epsilons or
> incorrectly quantizing the query rectangles in tests), hiding the above.
> 3. Both LatLonPoint and GeoPointField still have rounding issues at
> quantization. For very special values they do not always consistently round
> in one direction.
> 4. Random encoding tests will never find the above issue, hiding it. This is
> because you need very special double values that the current stuff (e.g.
> {{-180 + 360.0 * random().nextDouble()}} will never find!).
