title: HTML5: dragover(), drop(): how get current x,y coordinates?
body: <p>How does one determine the (x,y) coordinates while dragging "dragover" and after the drop ("drop") in HTML5 DnD?</p>
  
  <p>I found a webpage that describes x,y for dragover (look at e.offsetX and e.layerX to see if set for various browsers but for the life of me they ARE NOT set).</p>
  
  <p>What do you use for the drop(e) function to find out WHERE in the current drop target it was actually dropped?</p>
  
  <p>I'm writing an online circuit design app and my drop target is large.</p>
  
  <p>Do I need to drop down to mouse-level to find out x,y or does HTML5 provided a higher level abstraction?</p>
