void softpipe_set_framebuffer_state	(	struct pipe_context *	pipe,
		const struct pipe_framebuffer_state *	fb
	)

XXX this might get moved someday Set the framebuffer surface info: color buffers, zbuffer, stencil buffer.

Here, we flush the old surfaces and update the tile cache to point to the new surfaces.
