    backend: try gdk backend before x11/wayland/egl
    
    Quite a few people at Guadec complained of pinpoint being broken in
    speaker+fullscreen mode, with slides being half displayed. It turns
    out that the X11 backend of clutter was being used and this backend
    assumes the size of the current monitor is the size of the X screen
    (that's not the case with multiple monitors).
    
    To work around the shortcomings of the X11 backend we should probably
    position the GDK one before. GDK implements most of the logic the
    ClutterStage needs and is probably more tested.
