    window: Include STATE_CHANGED flag when tiling
    
    For size change animations, plugins rely on the size change effect being
    followed by size changed signal (or effects being kill altogether).
    However unless the move_resize operation included the STATE_CHANGED flag,
    the size changed event emitted when the compositor syncs the window
    geometry only happens when the operation resulted in an actual change.
    
    To avoid animations getting stuck in that case, make sure to include the
    flag when tiling a window.
