title: Qt - globally enable touch scrolling
body: <p>I've been using a wacom tablet lately on windows 10 and I do like how Windows natively supports gestural scrolling when you're using a tablet. In trying to implement this in my PyQt apps I was able to get kinetic scrolling working quite nicely with tablet events and a QScroller. However you need to do this for every (scrolling) widget you want to have support for it... So my question is: can this be somehow enabled globally? Perhaps this is a dumb question, but I think it would make sense to have this work for all widgets and scroll bars without reimplementing all over the place and extensive refactoring. Is there a clean way to replace all scroll areas or scroll bars throughout the app?</p>
