title: Flex Spark List Mouse Wheel Scroll Speed
body: <p>I have a component extending a Spark List, and when I scroll using the mouse wheel it scrolls too much in one go. I have tried looking for the handler that deals with mouse wheel scrolling in the List class and VerticalLayout class to override but I cannot find it.</p>
  
  <p>Is there another way I'm supposed to change this, or am I missing something?</p>
