* When Figure instance which corresponds to RootEditPart is updated, calculate the frame rate and set the
* measured rate to "frame_rate" property of the corresponding DisplayModel instance.
*
* 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.
