virtual void onDestroy(

Gets called the moment the object is marked for deletion by destroy().

See: destroy()

Warning: It is possible that the onDestroy() callback is never called when destroy() wasn't properly called. DiwneObjects containing other DiwneObjects should always ensure to destroy their children in their onDestroy().

Reimplements: DIWNE::Node::onDestroy

It is called only once per object.
