    js/ui: Use Clutter.OffscreenRedirect.ON_IDLE
    
    To bypass offscreening in cases where continuous animation is happening.
    Offscreening is slower in such cases so this reduces the render time of
    animations within offscreenable actors.
    
    On an i7-7700 this reduces the render time of boxpointers for example by
    25-30%.
