Computes the topological relationship (Location) of a single point to a Geometry.
The algorithm obeys the SFS boundaryDetermination rule to correctly determine whether the point lies on the boundary or not.

Computes the topological relationship (Location) of a single point to a Geometry. It handles both single-element and multi-element Geometries. The algorithm for multi-part Geometries takes into account the boundaryDetermination rule.
