The new full-screen exclusive mode API allows applications to
create a window that occupies the entire screen. If
GraphicsDevice.isFullScreenAvailable() returns true, then the
other top level windows, whether or not they've been created
by the full screen Java application, will not overlap the
full-screen window. Otherwise full screen mode is emulated
by resizing the window to the size of the screen and positioning
it at (0,0). There are no other behavorial changes to AWT
components in this mode.
