Global Mapper SDK
Performs the Intersects spatial predicate. The layer parameters aLayer1 and aLayer2 must not be NULL.The aParams's mPredicateResultTarget parameter specifies the result target type. If it's equal to GM_PredicateResult_CreateNewLayer, then the aParams' mResultLayerName parameter must not be NULL.
The result layer, if handle is returned in the aParams' mResultLayer member; it will be NULL if the operation fails.
