        // override the AddedToManager and RemovedFromManager functions, create and add your

        // widgets or remove and nuke them, and in the case of AddedToManager, you also had

        // to then place the widget using global coordinates that had no relation to the coordinates

        // you set the parent widget at. Not anymore. What we can do now is to dispense with

        // overriding those methods altogether! So now, in the parent's constructor, we can

        // create our child widgets, resize them, and place them using relative coordinates.

        // What this also means is that moving the parent widget around results in moving

        // ALL the child widgets, which means you no longer have to manually move everything

        // just because the parent moved. In addition, another nice thing is that you no longer

        // you could enforce that it's always drawn above any overlay layer, 

        // or you could do just the opposite. We'll

        // set it to 1, since in our Board::Draw method, you'll see that we 

        // toggle between drawing the overlay above and below this widget.
