 //! What is the importance of this class?
 //!
 //! This window is responsible to identify if the mouse is still present
 //! in the REAL FLOATING GAP between the VIEW and the SCREEN EDGE.
 //! When VIEWS are REAL FLOATING then the VIEW Window is really placed
 //! as it is shown to the user. In that case we need a way to check
 //! where the mouse is even though it is OUTSIDE the VIEW or the
 //! SCREENEDGEGHOSTWINDOW. The main functionality of FloatingGapWindow
 //! is that it is TEMPORARILY shown/draw after a MUSTHIDE signal of
 //! VisibilityManager was sent; in order to check if the mouse is still
 //! inside the FLOATINGGAP. After it has really identified where mouse
 //! is present, an FloatingGapWindow::asyncContainsMouse(contains) signal
 //! is sent.
