We had taken care of the prerequisites for this one a while ago, but
hadn't gotten around to committing this. I've gone ahead and done that
now.

So, cairo-xlib now has the following new API:

	cairo_public Display *
	cairo_xlib_surface_get_display (cairo_surface_t *surface);

	cairo_public Drawable
	cairo_xlib_surface_get_drawable (cairo_surface_t *surface);

	cairo_public Screen *
	cairo_xlib_surface_get_screen (cairo_surface_t *surface);

	cairo_public Visual *
	cairo_xlib_surface_get_visual (cairo_surface_t *surface);

	cairo_public int
	cairo_xlib_surface_get_depth (cairo_surface_t *abstract_surface);

For this one, I still don't think I've seen an updated patch
incorporating my comments. (I know the rectangle rename was a
prerequisite, and you supplied that a while ago, but I only committed
it now).
