    appDisplay: Allow a slighly bigger area for drag overshoot
    
    Now that we don't have the Frequent tab anymore, and subsequently
    the buttons to switch tabs, the app grid fill all the way to the
    bottom, leaving no room for drag overshoot.
    
    Add a 20px (i.e. OVERSHOOT_THRESHOLD) area at the bottom of the
    grid where dragging actually scrolls to the next page.
