title: $this->renderTotals() which renders block?
body: <p>Hello (sorry for my english)</p>
  
  <p>The file  <code>/app/design/frontend/my-theme/default/template/checkout/cart/totals.phtml</code> has the command:</p>
  
  <pre><code>    &lt;tbody&gt;
          &lt;?php echo $this-&gt;renderTotals(); ?&gt;
      &lt;/tbody&gt;
  </code></pre>
  
  <p>In my theme, not charge the purchase price in the shopping cart at: ... mystore.com / checkout / cart /</p>
  
  <p><code>$this-&gt;renderTotals()</code> renders which block?</p>
