issue with running example from the canvas 2D tutorial.

[magp3]

I went here: http://doc.babylonjs.com/tutorials/using_the_canvas2d

And followed the playground link to here: https://www.babylonjs-playground.com/#2AVSFH#35

Since I'm rather new to this, I'm not sure if I'm missing something or it's not working.

It does not render anything for me and I get this error message:

babylon.canvas2d.min.js:4 Uncaught TypeError: e.Tools.getClassName is not a function
    at o.get [as modelKey] (babylon.canvas2d.min.js:4)
    at o.n._createModelRenderCache (babylon.canvas2d.min.js:7)

Unfortunately we do not support canvas anymore.
I highly recommend using GUI instead: doc.babylonjs.com/overviews/gui
