title: Trigger 'dummy' mouse wheel event
body: <p>Is there a way to trigger a scroll wheel event with an arbitrary delta.
  Just like jQuery does with 'click' like:</p>
  
  <pre><code>$('#selector').trigger('click');
  </code></pre>
  
  <p>I need something like that just with an scrollwheel like:</p>
  
  <pre><code>$('#selector').trigger('DOMMouseScroll',{delta: -650});
  //or mousewheel for other browsers
  </code></pre>
  
  <p>I can't do anything like 'fake it' with css trickery, I need to trigger the actual native (or as close as possible) event.</p>
  
  <p>Thankyou!</p>
