Description
Notifies the canvas that a graphics object is created or removed.
Notification is used internally by the canvas object. Notification is called automatically whenever a new graphics object is attached to the canvas, or an old one is removed from the canvas.
Notification accepts two parameters. AD2DObject is the object being added or removed. Operation is the actual operation being performed--addition or removal of the object to, respectively from the canvas.
Note: Notification does not free the graphical objects if they are removed. Notification simply removes the object reference from an internal list.
