/**
 * The JGoodies Plastic Look&Feel implementation of
 * {@code TabbedPaneUI}. It differs from its superclass
 * {@code MetalTabbedPaneUI} in that it paints new tab shapes,
 * provides two options, and supports ClearLook.
 *

 * You can enable or disable icons in tabs globally via
 * com.jgoodies.looks.Options.setTabIconsEnabled(boolean).
 *

 * To disable the content border set
 *

 * JTabbedPane tabbedPane = new JTabbedPane();
 * tabbedPane.putClientProperty(Option.NO_CONTENT_BORDER_KEY, Boolean.TRUE);
 *

 * To paint embedded tabs use
 *

 * JTabbedPane tabbedPane = new JTabbedPane();
 * tabbedPane.putClientProperty(Option.EMBEDDED_TABS_KEY, Boolean.TRUE);
 *

 *

 * There's a special mode that helps you detect content borders in
 * heavily wrapped component hierarchies - such as the NetBeans IDE.
 * In this marked mode the content border is painted as a Magenta line.
 * You can enable this mode by setting the System property
 * <tt>markContentBorders</tt> to <tt>true</tt>; in a command line:
 *

 * java -DmarkContentBorders=true
 *

 *
 * Thanks to Andrej Golovnin for his feedback and suggestions.
