This driver does no transformation of the gallium calls
	going to the real driver, like the identity matrix. It is
	intended to be the basis for transforming and/or debug
	drivers like trace and rbug.

	Authors of this patch are:
		Michal Krol, orignal heavy lifting.
		José Fonesca, object wrapping code stolen from trace.
		Jakob Bornecrantz, put it all toghether and renamed a stuff.
