      public final class PlasticTabbedPaneUI
      extends MetalTabbedPaneUI

  The JGoodies Plastic Look&Feel implementation of `TabbedPaneUI`. It differs from its superclass `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 `markContentBorders` to `true`; in a command line:

       java -DmarkContentBorders=true

  Thanks to Andrej Golovnin for his feedback and suggestions.
