 * @bug 5096011
 * @bug 5101712
 * @bug 5098624
 * @summary Here are a few assertions worth verification:
 *  - the fullscreen window is positioned at 0,0
 *  - the fs window appears on the correct screen
 *  - if the exclusive FS mode is supported, no other widndow should
 *    overlap the fs window (including the taskbar).
 *    You could, however, alt+tab out of a fullscreen window, or at least
 *    minimize it (if you've entered the fs mode with a Window, you'll need
 *    to minimize the owner frame).
 *    Note that there may be issues with FS exclusive mode with ddraw and
 *    multiple fullscreen windows (one per device).
 *  - if display mode is supported that it did change
 *  - that the original display mode is restored once
 *    the ws window is disposed
 *  All of the above should work with and w/o DirectDraw
 *  (-Dsun.java2d.noddraw=true) on windows, and w/ and w/o opengl on X11
 *  (-Dsun.java2d.opengl=True).
