title: Scrolling lag with GestureDetector onScroll
body: <p>I use <code>GestureDetector</code> to implement scrolling inside a custom <code>View</code>. My implementation is based on this: <a href="https://stackoverflow.com/questions/5003069/smooth-scrolling-with-inertia-and-edge-resistance-snapback/5003186#5003186">Smooth scrolling with inertia and edge resistance/snapback</a></p>
  
  <p>I noticed a short pause before the scrolling starts: I examined the <code>onScroll</code> messages and noticed that the first one arrives only after a larger movement of a finger, which causes noticable lag at the beginning of the scrolling. After that the scrolling is smooth.</p>
  
  <p>It seems <code>GestureDetector</code> starts sending <code>onScroll</code> messages only after a minimal distance between the motionevents to make sure the gesture is not a longtap or tap (btw I set <code>setIsLongpressEnabled(false)</code>).</p>
  
  <p>Is there any way to change this behaviour and create a smooth scroll without implementing a custom scroll gesture using low level touch events?</p>
