Additional Inherited Members
Static Public Member Functions inherited from OpenGl_Element
template<typename theResource_t >
static void	Destroy (OpenGl_Context *theContext, theResource_t *&theElement)
	Pointer to the context is used because this method might be called when the context is already being destroyed and usage of a handle would be unsafe.
