GrGLMakeAssembledInterface()

sk_sp< const GrGLInterface > GrGLMakeAssembledInterface	(	void *	ctx,
		GrGLGetProc	get
	)

Generic function for creating a GrGLInterface for an either OpenGL or GLES. It calls get() to get each function address. ctx is a generic ptr passed to and interpreted by get().
