Data Fields
uint32_t	magic
	Magic code which confirms this is a reference.

vx_enum	type
	Set to an enum value in vx_type_e.

vx_context	context
	Pointer to the top level context. If this reference is the context, this will be NULL.

vx_reference	scope
	The pointer to the object's scope parent. When virtual objects are scoped within a graph, this will point to that parent graph. This is left generic to allow future scoping variations. By default scope should be the same as context.

char	name [VX_MAX_REFERENCE_NAME]
	Reference name.

vx_uint32	external_count
	The count of the number of users with this reference. When greater than 0, this can not be freed. When zero, the value can be considered inaccessible.

vx_uint32	internal_count
	The count of the number of framework references. When greater than 0, this can not be freed.

tivx_reference_callback_f	mem_alloc_callback
	Object specific function that is called to allcoate object memory.

tivx_reference_callback_f	destructor_callback
	Object specific function that is called to destroy an object when refernce count reaches zero.

tivx_reference_release_callback_f	release_callback
	Object specific function that is called to release an object.

tivx_mutex	lock
	Lock to take for the reference.

vx_bool	is_virtual
	This indicates if the object is virtual or not.

vx_bool	is_accessible
	Can this reference be accessed by user application Used for virtual reference's only.

vx_bool	is_array_element
	Indicates that the object is an element of a pyramid or object array.

tivx_obj_desc_t *	obj_desc
	object descriptor
