title: UIScrollView scrolling with indicator only
body: <p>Intent (iPad): I've got a UIScrollView that's very sensitive to interaction so I'd like to have a large (finger sized) indicator that the user has to to use to scroll.</p>
  
  <p>Problem: From what I can tell the only built-in UIScrollView indicator customisation is 'scrollIndicatorInsets' and 'Indicator Style', but neither of these effect size.</p>
  
  <p>Does anybody know of a work around or am I going to have to make my own scrollbar from scratch?</p>
