I would prefer if you used the time from the originating X event. Would it be
hard?

At the moment, this doesn't work, since |views::Event::time_stamp_| is never set
in non-Windows.

 
   // The event and all the touches have been updated. Dispatch.
   host_->ForwardTouchEvent(touch_event_);
 
   // If the touch was released, then remove it from the list of touch points.
   if (e.GetType() == views::Event::ET_TOUCH_RELEASED) {
     --touch_event_.touchPointsLength;
     for (int i = point - touch_event_.touchPoints;
          i < touch_event_.touchPointsLength;
          ++i) {
       touch_event_.touchPoints[i] = touch_event_.touchPoints[i + 1];
     }
   }
 
   return true;
 }
