[mutter/wip/carlosg/input-in-backends: 165/176] clutter/cally: Remove needless per-backend code in cally

    clutter/cally: Remove needless per-backend code in cally
    
    We can poke the X11 stage to translate to root coordinates, or just assume
    the compositor will cover the root window area and avoid per-backend behavior
    here.
