  36  * The {@code GraphicsDevice} class describes the graphics devices
  37  * that might be available in a particular graphics environment.  These
  38  * include screen and printer devices. Note that there can be many screens
  39  * and many printers in an instance of {@link GraphicsEnvironment}. Each
  40  * graphics device has one or more {@link GraphicsConfiguration} objects
  41  * associated with it.  These objects specify the different configurations
  42  * in which the {@code GraphicsDevice} can be used.
  43  * <p>
  44  * In a multi-screen environment, the {@code GraphicsConfiguration}
