/**
 * QuaquaIconFactory.
 *
 * @author  Werner Randelshofer, Christopher Atlan
 * @version 3.2 2007-01-05 Issue #1: Changed LazyOptionPaneIcon to load image
 * asynchronously before paintIcon is invoked.
 * <br>3.1 2006-12-24 by Karl von Randow: Use Images class to create artwork.
 * <br>3.0.2 2006-11-01 Use Graphics2D.drawImage() to scale application
 * image icon instead of using Image.getScaledInstance(). 
 * <br>3.0.1 2006-05-14 Application icon was unnecessarily created multiple
 * times. 
 * <br>3.0 2006-05-12 Added support for file icon images. Renamed some
 * methods.
 * <br>2.1 2006-02-14 Added method createFrameButtonStateIcon.
 * <br>2.0 2006-02-12 Added methods createApplicationIcon, compose,
 * createOptionPaneIcon. These methods were contributed by Christopher Atlan.
 * <br>1.0 December 4, 2005 Created.
