From Wojciech Lewandowski, "I am sending a really minor fix for StatsHandler::reset method. We dynamically add and remove slave cameras in our application. StatsHandler does not automatically adapt to this situation, and we call StatsHandler::reset to force it to update number of cameras and their graphs. Unfortunately, if stats were already drawn, reset would not remove former graph drawables and they would remain frozen below new stats. This update fixes it.
