Save to your folder(s)
For this to work you need get Mr.Doob's Stats class and put it in the 'net/hires/debug' package structure. This code basically makes the stats hidden until you double-click in the top-left corner of the stage. The stats are then draggable and can be hidden again by double-clicking the stats panel.
