/**
 * Factory object that vends <code>Icon</code>s for
 * the Java<sup><font size="-2">TM</font></sup> look and feel (Metal).
 * These icons are used extensively in Metal via the defaults mechanism.
 * While other look and feels often use GIFs for icons, creating icons
 * in code facilitates switching to other themes.
 *
 * <p>
 * Each method in this class returns
 * either an <code>Icon</code> or <code>null</code>,
 * where <code>null</code> implies that there is no default icon.
 *
 * <p>
 * <strong>Warning:</strong>
 * Serialized objects of this class will not be compatible with
 * future Swing releases. The current serialization support is
 * appropriate for short term storage or RMI between applications running
 * the same version of Swing.  As of 1.4, support for long term storage
 * of all JavaBeans<sup><font size="-2">TM</font></sup>
 * has been added to the <code>java.beans</code> package.
 * Please see {@link java.beans.XMLEncoder}.
