Parameters

op	Modification of geometry
shapes	Geometry objects assumed to be inputs of op. The corresponding values in the map dictate the behavior of the resulting metadata.
typesToTraverse	Traverse the subshapes of shapes with these types. An empty list means only shapes will be examined.

Returns
