/**
 *  This example tests the sizing/positioning methods of Shell widgets.
 *  It creates five windows arranged chessboard fashion with the top window
 *  in the center and secondary windows exactly in the corners of the screen.
 *  First time the sizing/positioning is made using setBounds() method,
 *  second time (after the top window is closed) -- using setLocation()/setSize()
 *  methods.
