'''OpenGL extension EXT.texture_object

Overview (from the spec)
	
	This extension introduces named texture objects.  The only way to name
	a texture in GL 1.0 is by defining it as a single display list.  Because
	display lists cannot be edited, these objects are static.  Yet it is
	important to be able to change the images and parameters of a texture.

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