Description

GeometriesChanged flags that the geometries have been changed. It also marks a top level geometry as being non-simple. Use it when manipulating the parts of a geometry directly (for example, rotating a ring). The top level geometry won't know that its cached envelope, length, centroid, etc. are invalid until this method is used.
