/**
* <p>A {@link org.jdesktop.swingx.painter.Painter} enabled subclass of {@link javax.swing.JButton}.
* This class supports setting the foreground and background painters of the button separately.</p>
*
* <p>For example, if you wanted to blur <em>just the text</em> on the button, and let everything else be
* handled by the UI delegate for your look and feel, then you could:
* <pre><code>
* JXButton b = new JXButton("Execute");
* AbstractPainter fgPainter = (AbstractPainter)b.getForegroundPainter();
* StackBlurFilter filter = new StackBlurFilter();
* fgPainter.setFilters(filter);
* </code></pre>
*
* <p>If <em>either</em> the foreground painter or the background painter is set,
* then super.paintComponent() is not called. By setting both the foreground and background
* painters to null, you get <em>exactly</em> the same painting behavior as JButton.</p>
