If one put a JDesktopPane inside a JScrollPane,
and create JInternalFrames larger than the desktop,
the scrollbars don't appear. The code below
demonstrates the problem:

// some class, main method
  {
    JDesktopPane desktop = new JDesktopPane();
    JScrollPane scroll = new JScrollPane( desktop );
    JInternalFrame frame = new JInternalFrame( "frame" );
    desktop.add( frame );
    desktop.setPreferredSize( new Dimension( 200, 300 ) ); // small desktop
    frame.setBounds( 10, 10, 400, 500 ); // with a big internal frame inside

    JFrame f = new JFrame();
    f.getContentPane().add( scroll );
    f.pack();
    f.show();
  }

The scrollpane uses the *preferred size* of the desktop
to decide whether it has to show the scrollbars or not.
It should use the *contents* (the internal frames and
desktop icons) to do it.

I think JDesktopPane should implement the Scrollable
interface, managing its contents to produce the desired
result.

THIS A VERY SERIOUS BUG!!! EVERYONE WHO USES
INTERNAL FRAMES CAN SEE IT!!!

Add scrollability to JDesktopPane similarily to JTextArea. When a JDesktopPane
is placed on a JScrollPane, allow the JDesktopPane to change its preferred size
according to placement of all the JInternalFrame components on it, so that when
some of them are outside the viewed area the JScrollPane can show scrollbars.
