Detailed Description

Computes the contains spatial relationship predicate for a PreparedPolygon relative to all other Geometry classes.

Uses short-circuit tests and indexing to improve performance.

It is not possible to short-circuit in all cases, in particular in the case where the test geometry touches the polygon linework. In this case full topology must be computed.
