        // since there was no notion of parent/child relationship. What you had to do was
        // 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
        // have to remove your child widgets before deleting them: this is handled automatically

        // with a lower priority. Thus, by changing the priority of a widget,
        // you could enforce that it's always drawn above any overlay layer,
