636             @descr  Note: Showing of a frame is bound to a special feature ...
637                     a) If we recycle any existing frame, we must bring it to front.
638                        Showing of such frame isn't needed really .. because we recycle
639                        visible frames only!
640                     b) If the document was already shown (e.g. by our progress implementation)
641                        we do nothing here. The reason  behind: The document was already shown ..
642                        and it was already make a top window ...
643                        If the user activated another frame inbetween (because loading needed some time)
644                        it's not allowed to disturb the user again. Then the frame must resists in the background.
645                     c) If the frame was not shown before ... but loading of a visible document into this frame
646                        was finished ... we need both actions: setVisible() and toFront().
647 
648             @param  xWindow
649                     points to the container window of a frame.
650 
651             @param  bForceToFront
652                     if it's set to sal_False ... showing of the window is done more intelligent.
653                     setVisible() is called only if the window was not shown before.
654                     This mode is needed by b) and c)
655                     If it's set to sal_True ... both actions has to be done: setVisible(), toFront()!
656                     This mode is needed by a)
