> LatLonPoint methods are calling {{*precise()}} methods such as rectCrossesPolyPrecise(). GeoPointMethods are calling {{*approx()}} methods such as rectCrossesPolyApprox().
> I don't understand why we have two versions of these methods, why one is approximate, why we would ever use that, etc.
> These geo methods are extremely expensive: we can't afford two copies. For example, in the case of these polygon methods, they are still missing direct tests. We need to remove one copy of these. I propose to remove the approx ones.
