> This is a continuation of LUCENE-6908 which validates USGS accuracy of 0.5% 
> for Sinnott haversine distance calculation. The issue also introduced a space 
> segmentation approach for BKD distance queries near the poles. In LUCENE-6956 
> a restriction on distance size was initially removed to randomly test BKD 
> distance queries at any range. This revealed an issue where distance error 
> nearly doubles for exotic rectangles created by BKD's split algorithm. This 
> issue will investigate potential distance error caused by the segmentation 
> approach introduced in the second part of LUCENE-6908.
