                 * <code>MetalTreeUI</code> allows for configuring how to
                 * visually render the spacing and delineation between nodes. The following

                 * <td>A line is drawn connecting the child to the parent. For handling
                 * of the root node refer to
                 * {@link javax.swing.JTree#setRootVisible} and
                 * {@link javax.swing.JTree#setShowsRootHandles}.

                 * <th><p style="text-align:left">None</p></th>

                 * <p>
                 * As it is typically impractical to obtain the <code>TreeUI</code> from
                 * the <code>JTree</code> and cast to an instance of <code>MetalTreeUI</code>
                 * you enable this property via the client property
                 * <code>JTree.lineStyle</code>. For example, to switch to
                 * <code>Horizontal</code> style you would do:
                 * <code>tree.putClientProperty("JTree.lineStyle", "Horizontal");</code>
                 * <p>
                 * The default is <code>Angled</code>.
