Description

Overlaps, Touches, Within all imply geometries are not spatially disjoint. If any of the aforementioned returns true, then the geometries are not spatially disjoint. Disjoint implies false for spatial intersection.

	Do not call with a GEOMETRYCOLLECTION as an argument

Performed by the GEOS module

	This function call does not use indexes

	NOTE: this is the "allowable" version that returns a boolean, not an integer.
