     *    status->viewport_x and status->viewport_y reflect viewport position at the time of such

     *          where ClickToFocus is requested ). To Accomplish that we grab mouse
     *          events on all the windows but currently focused.
     * Secondly we need to hilite currently active window with frame decorations, when window
     *          gets focus. So right after focus is forced on window and before FocusIn event
     *          we'll have : (focused == ungrabbed) != hilited
     * Thirdly, we may need to steal focus for our own needs while we perform housekeeping
     *          like desk switching, etc. ( GrabEm/UngrabEm ) In such situation window
     *          remains hilited, but has no focus, and has no pointer event grabs.
     *          (focused == NULL) != (ungrabbed == hilited)
     * Fourthsly, When housekeeping is completed we want to give the focus back to it, but
     *          in some situations housekeeping operations will make us give the focus to
     *          some other window. To do that we substitute focused pointer to new window
     *          right before UngrabEm. In this case focused != ( ungrabbed == hilited )

 * calculations. Note that we only do that for placement purposes. Contexts and images are
