'''OpenGL extension ATI.vertex_array_object

Overview (from the spec)
	
	This extension defines an interface that allows multiple sets of
	vertex array data to be cached in persistent server-side memory.
	It is intended to allow client data to be stored in memory that
	can be directly accessed by graphics hardware.
	

The official definition of this extension is available here:
	http://oss.sgi.com/projects/ogl-sample/registry/ATI/vertex_array_object.txt
