…e unit conversion properly from distance (meters, km, etc.) to decimal degrees (EPSG:4326 long/lat). There is still a degree of error difficult to compensate for when dealing polygons (e.g a country). Future work will adopt a more accurate approach consistent with other LocationTech projects

Add 'some' support date line crossing for the DWITHIN function
Clip hemisphere crossing. A separate issue will be made for dealing the
poles.
