title: How to remember scroll position and scroll back
body: <p>I am using html2canvas library and when I call html2canvas.Parse() the page scroll to top.</p>
  
  <p>I thought if i can remember the position before calling html2canvas.Parse(), so then i can go back to original scroll position.</p>
  
  <ol>
  <li>get the current position of browser scroll (specially vertical)?</li>
  <li>scroll back to position which i stored earlier?</li>
  </ol>
