    tdf#127939: Make slideshow touch input work properly again on iOS 13
    
    For some reason, navigator.userAgent in WebKit on iOS 13 claims it to
    be a Macintosh, so our old code to recognise iOS did not work any
    longer. Also the Hammer.js included in this file looked at
    navigator.userAgent and its decision what to do based on that did not
    work properly either.
    
    Simplify our code by handling swipe gestures all the time, even when
    such won't be generated (on mouse-only devices).
    
    Also, Hammer.JS was too eager to think it detected a pointer-only
    device based on the presense of window.PointerEvent. That sems to be
    present now in iOS 13. Let's not blindly think that means it is a
    pointer-only device. If the device supports touch events, don't bother
    with PointerEvents.
