Robert Osfield	644b2e15d1	Refactored the osg::Observer to introduce a new bool Observer::objectUnreferenced(void*) method that adds ... the extra capability of making it possible for Observers to assume ownership of a object that would otherwsie be deleted. Added a thread safe ref_ptr<T> observer_ptr<T>::lock() method for robust access to an observed object. This makes observer_ptr<> more equivilant to boosts weak_ptr.	2010-02-15 20:12:53 +00:00
