 * <ul>

 * <li>a {@link javax.swing.JComponent} - in the

 *     {@link javax.swing.JComponent#paint(Graphics)} method, the incoming

 *     {@link Graphics} should always be an instance of

 *     {@link Graphics} should always be an instance of

 *     <code>Graphics2D</code>.</li>

 * </ul>

 * <p>

 * Third party libraries provide support for output to other formats via this

 * API, including encapsulated postscript (EPS), portable document format (PDF),

 * and scalable vector graphics (SVG).
