         * By default, org.eclipse.draw2d.DeferredUpdateManager is used. This update manager queues update requests from
         * figures and others, and it repaints requested figures at once when GUI thread is ready to repaint.
         * notifyPainting() method of UpdateLister is called when it repaints. The frame rate is calculated based on the
         * timing of notifyPainting().
         *
         * Note that the update manager repaints only requested figures. It does not repaint all figures at once. For
         * example, if there are only two widgets in one display, these widgets might be repainted alternately. In that
         * case, the frame rate indicates the inverse of the time between the repainting of one widget and the
         * repainting of the other widget, which is different from our intuition. Thus, you have to be careful about the
         * meaning of "frame rate" calculated by the following code.
