A component may * support one or more regions.  Specific component regions are defined * by the typesafe enumeration in this class. * <p> * Regions are typically used as a way to identify the <code>Component</code>s * and areas a particular style is to apply to. Synth's file format allows you  * to bind styles based on the name of a <code>Region</code>.   * The name is derived from the field name of the constant: * <ol> *  <li>Map all characters to lowercase. *  <li>Map the first character to uppercase. *  <li>Map the first character after underscores to uppercase. *  <li>Remove all underscores. * </ol> * For example, to identify the <code>SPLIT_PANE</code> * <code>Region</code> you would use <code>SplitPane</code>. * The following shows a custom <code>SynthStyleFactory</code>  * that returns a specific style for split panes: * <pre> *    public SynthStyle getStyle(JComponent c, Region id) { *        if (id == Region.SPLIT_PANE) { *            return splitPaneStyle; *        } *        ... *    } * </pre> * The following <a href="doc-files/synthFileFormat.html">xml</a> * accomplishes the same thing: * <pre> * &lt;style id="splitPaneStyle"> *   ... * &lt;/style> * &lt;bind style="splitPaneStyle" type="region" key="SplitPane"/> * </pre> * * @version 1.30, 02/19/04 * @since 1.5 * @author Scott Violet */public class Region {    private static final Map uiToRegionMap = new HashMap();    private static final Map lowerCaseNameMap = new HashMap();    /**     * ArrowButton's are special types of buttons that also render a     * directional indicator, typically an arrow.
