title: javascript smooth animation from X,Y to X1,Y1
body: <p>I'd like to sloothly move an image (or an element) from its actual X, Y location to X1, Y1.</p>
  
  <p>When the <strong>distance</strong> between X and X1 <strong>is equal</strong> to that between Y and Y1 its easy.
  But what if the X difference is say 100px and Y diff is 273px?</p>
  
  <p>Being new to Javascript, I don't want to re-invent the wheel!
  Besides, since I'm learning, I do NOT want to use jQuery or the likes. I want pure javascript.</p>
  
  <p>Please supply with simple script :-)</p>
