     * This method does two things: it fills the point fields with
     * the current coordinates of the mouse cursor and returns the
     * number of the screen device where the pointer is located.
     * The number of the screen device is only returned for independent
     * devices (which are not parts of a virtual screen device).
     * For virtual screen devices, 0 is returned.
     * Mouse coordinates are also calculated depending on whether
     * or not the screen device is virtual. For virtual screen
     * devices, pointer coordinates are calculated in the virtual
     * coordinate system. Otherwise, coordinates are calculated in
     * the coordinate system of the screen device where the pointer
     * is located.
     * See java.awt.GraphicsConfiguration documentation for more 
     * details about virtual screen devices.

     * Returns whether or not the window is located under the mouse
     * pointer. The window is considered to be under the mouse pointer
     * if it is showing on the screen, and the mouse pointer is above
     * the part of the window that is not obscured by any other windows.
