title: Detect dead scrolling at the bottom of the page (mousewheel, scroll events)
body: <p>I'm looking to detect when a user has scrolled to the bottom of a page and then attempts to continue scrolling but where there's nothing left to scroll/view. </p>
  
  <p>I'm creating usability metrics where dead scroll is one metric and need a way to accurately detect when users try to scroll but are not offered anything left to see.</p>
  
  <p>I need something that fires when the mousewheel event initiates but the page does not scroll, with up/down direction.</p>
