     *  Dynamic skin parts should always be instantiated by this method, 
     *  rather than directly by calling the <code>newInstance()</code> method on the factory.
     *  This method creates the part, but does not add it to the display list.
     *  The component must call the <code>Group.addElement()</code> method, or the appropriate 
     *  method to add the skin part to the display list. 
     *
     *  @param partName The name of the part.
