title: Chrome and IE: parallax (jQuery animate) is not smooth when using mouse wheel to scroll
body: <p>I adapted <strong><a href="http://www.ianlunn.co.uk/plugins/jquery-parallax/" rel="noreferrer">this</a></strong> plugin for jQuery that uses the parallax effect for my website.
  Problem is (even in the demo in the link above) that Chrome and IE have a really NOT smooth scroll.. it only works well when you press the middle button on the mouse and the scroll is continuous (not "step-by-step" when you scroll the mouse wheel). So when you use the mouse wheel to scroll, the parallax effect is completely ruined. In Firefox instead the scroll is continous even when scrolling with the mouse wheel. Is there a way to have continous scrolling in IE and Chrome too (javascript?).</p>
