title: Showing part of an ImageIcon
body: <p>Bonjour,
  I'm trying my hand at animation, and have found myself a strip of explosions on a single image in a row. I want them to show one after the other in sequence to animate an explosion. Naturally, I'm thinking <code>ImageIcon</code> on <code>JLabel</code>, but when I looked at the <code>JLabel</code> spec I found this line:</p>
  
  <blockquote>
    <p><code>JLabel(Icon icon)</code>  --  Creates a <code>JLabel</code> instance with the specified image. The label is centered vertically and horizontally in its display area.</p>
  </blockquote>
  
  <p>I want to be able to show only part of a full image in the label, then load another part of it: basically loading the different stages on the one image.</p>
  
  <p>Is there a way to do this without cutting up the image and loading each one individually?</p>
