    clutter: Check updated devices with the current clip
    
    We do check the clip area as an optimization to know which input devices
    might need updating state after a relayout (Assuming that if a device is
    under a non-painted area, it's actor beneath didn't change).
    
    Use the clip region for this, and drop the last usage of the clip region
    bounds.
