This method is called by Carmenta Engine during selection, to determine if a feature is "hit" by the selection rectangle. It is up to the custom visualizer to determine what a hit is.
If the method returns True, a presentation object representing the visualization of the feature will be created and returned to the caller, usually via View.WhatsIn.
