Looks reasonable

 const char *    gnome_rr_output_get_display_name   (GnomeRROutput         *output);
 gboolean        gnome_rr_output_is_connected       (GnomeRROutput         *output);

huh, this was in the header but not implemented ?

GnomeRR: read the physical output size for mutter

And expose it in the API, so that the control center can use it
to show the diagonal and aspect ratio.

This is rebased on master. It does not implement get_size_inches()
as requested, because the code to do that is gone. It could be
resurrected, but I think it makes more sense in gnome-control-center
