* Most of the time, apps only react to events (touch events, for example).
* In this case you don't need to do anything in this method.
*
* For example, InfiniPaint does nothing in Refresh().
* But, if you want to update your display periodically, draw an animation...
* you cannot do it in a touch event handler because these handlers are not
* called if the user does not touch the screen.
*
* That's why Refresh() is there: update the display periodically.
