title: Can't get Outer Dimensions of Circle with stroke-width, but Chrome can
body: <p>Please see <a href="http://jsfiddle.net/Lh3Um/22/" rel="nofollow">http://jsfiddle.net/Lh3Um/22/</a> for the demo w/complete problem description.</p>
  
  <p>Briefly: I can't figure out how Chrome debugger is reporting '46 x 46' for the circle element with a radius of 20px and a stroke of 5px in my svg.</p>
  
  <p>Neither <code>getBBox()</code> nor <code>getBoundingClientRect()</code> gives me that value. Oddly, in this case <code>getBoundingClientRect()</code> reports the same dimension as <code>getBBox()</code>; before it's always reported "45 x 45" - not 100% accurate, but at least closer to what I want.</p>
  
  <p>Can anyone tell me how Chrome is getting the "46 x 46" dimension, and if I can make that call in javascript? I don't care about browser compatibility.</p>
