Hey!

it seems that the NullEngine is trying to render AdvancedDynamicTextures - is this correct behaviour and should I work around this when running tests or should we do a PR when AdvancedDynamicTextures are ignored in NullEngine?

```auto
 console.error
      TypeError: Cannot set property 'font' of null
          at AdvancedDynamicTexture._render (.../@babylonjs/gui/2D/advancedDynamicTexture.js:626:21)
          at AdvancedDynamicTexture._checkUpdate (.../@babylonjs/gui/2D/advancedDynamicTexture.js:618:14)
          at Observer.callback (.../@babylonjs/gui/2D/advancedDynamicTexture.js:127:107)
          at Observable.notifyObservers (.../@babylonjs/core/Misc/observable.js:286:49)

```

Thanks

I think it’s expected behaviour for the null engine but I will let @Deltakosh or @sebavan say for sure.

I am totally not sure that ADT is null engine “friendly” as it works of a context 2d which is not available as well in node.

Okay so I should take care of this manually and check if the env is test.

Would it be a good idea to have BB take care of this automatically when using NullEngine thou? To me it seems logical that the ADT would be completely ignored.

I tend to agree but I would not want to bloat ADT code with a lot of not required tests

Do you think you could try to submit a PR with suggested changes?
