We appear to be using that in weston, but I'm not seeing prior usage of
it in wayland.  I'm guessing platform compatibility considerations are
stronger for wayland than weston, particularly for the scanner since it
needs to work everywhere we expect the protocols to be used; whereas in
weston if the demo clients don't work on certain platforms it isn't the
end of the world.
