title: Raphael center of scale in transform method
body: <p>Right now I'm using:</p>
  
  <pre><code>r.forEach(
      function (el) {
        el.scale(0.5, 0.5, 0.0, 0.0);
      });
  </code></pre>
  
  <p>to scale each object around (0/0), which is working fine.</p>
  
  <p>The Raphael reference however states that the scale function is deprecated and I'm supposed to use Raphael.transform(...) instead.</p>
  
  <p>I tried:</p>
  
  <pre><code>r.forEach(
      function (el) {
        el.transform("S(0.5)");
      });
  </code></pre>
  
  <p>however, this will scale the paths using the image center as the center of scale. How can I achieve the same effect with the transform function?</p>
