Returns whether point lies on or near path, within the specified tolerance in meters.
path is composed of great circle segments if geodesic is YES, and of rhumb (loxodromic)
segments if geodesic is NO.
See also GMSGeometryIsLocationOnPath(point, path, geodesic).
The tolerance, in meters, is relative to the spherical radius of the Earth. If you need to work
on a sphere of different radius, you may compute the equivalent tolerance from the desired
tolerance on the sphere of radius R: tolerance = toleranceR * (RadiusEarth / R), with
RadiusEarth==6371009.
