    clutter: Trigger pointer repick after animatable property changes
    
    This is notably necessary with transformations, since these don't
    trigger allocation machinery, but may affect the actor under the
    pointer.
    
    Visible e.g. with GNOME Shell's "Application does not respond"
    dialogs.
