* Use a Column element to position QML and video frame rate counters. * When using small-screen layouts, hide frame rate counters when dialogs or menus are displayed. * Do not display instantaneous frame rate. If changes in this rate trigger a repaint, then the rate itself is changed. If the repaint occurs in less time than the QElapsedTimer resolution, the displayed instantaneous rate is always zero. * Add a label, so it is clear which is the QML repaint rate, and which is the video frame rate.
