This method returns a user-clicked polygon on the map, using the specified line color while tracking.
This method will block the user interface (UI) thread until the user has completed tracking the Polygon. The method can be cancelled if the ESC key is pressed after the method has been called or the CancelTracking()()() method is called; in this case the method will return nullNothingnullptra null reference (Nothing in Visual Basic).
