>
> The {{.testGeoRelations}} method doesn't exactly test the behavior of
> GeoPoint*Query as its using the BKD split technique (instead of quad cell
> division) to divide the space on each pass. For "large" distance queries this
> can create a lot of irregular rectangles producing large radial distortion
> error when using the cartesian approximation methods provided by
> {{GeoUtils}}. This issue improves the accuracy of GeoUtils cartesian
> approximation methods on irregular rectangles without having to cut over to
> an expensive oblate geometry approach.
