Public Member Functions inherited from OpenGl_Resource
	OpenGl_Resource ()
	Empty constructor. More...
virtual	~OpenGl_Resource ()
	Destructor. Inheritors should call Clean (NULL) within it. More...

	Empty constructor. More...
	Standard_Transient (const Standard_Transient &)
	Copy constructor – does nothing. More...
