    wayland: Make wayland move/resizes be constrained the same as X11
    
    Just like we do for _NET_WM_MOVERESIZE messages on X11, consider
    wayland client move/resizes as "frame actions" so that the same
    constraints are applied to them, in particular the titlebar visibility
    constraint.
