The Debug panel now works in WebGL mode. Pay attention to the warning at the top of the Debug docs (feature request #499)
All the Debug methods have had the word 'render' removed from the start. So where you did `debug.renderSpriteInfo` before, it's now just `debug.spriteInfo`.
Debug methods that rendered geometry (Rectangle, Circle, Line, Point) have been merged into the single method: `Debug.geom`.
