title: Raphael, get elements angle after transform
body: <p>As is displayed here: <a href="http://raphaeljs.com/reference.html#Element.transform" rel="nofollow">http://raphaeljs.com/reference.html#Element.transform</a></p>
  
  <p>Raphael's transform allows me to move the element, but without changing the element's attributes.</p>
  
  <p>But as is explained here: <a href="http://grokbase.com/t/gg/raphaeljs/126j03p95c/get-x-y-coordinates-after-transformation" rel="nofollow">http://grokbase.com/t/gg/raphaeljs/126j03p95c/get-x-y-coordinates-after-transformation</a> it is possible to get a rectangle's post transformation x and y values.
  But what I can't figure out is how to get post-transformation <i>angle</i> of the rectangle.</p>
  
  <p>How do I do that?</p>
