Description

Overlaps, Touches, Within all imply spatial intersection. If any of the aforementioned returns true, then the geometries also spatially intersect. Disjoint implies false for spatial intersection.

	Do not call with a GEOMETRYCOLLECTION as an argument

Performed by the GEOS module

	This function call will automatically include a bounding box comparison that will make use of any indexes that are available on the geometries.

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