I would like to test Cesium in an environment where i have only access to a gl rendering context and its rendering context. Right now i cant because the `Viewer` class is hardly bound to html.  
My question is this, is it possible to use Cesium without the `Viewer` class? Is there any example of this?

To give more context i want to test Cesium inside Nativescript which is cross platform mobile framework.  
In there we have a plugin which gives us a `WebGL2RenderingContext` context which we can pass to most webgl libs like Three / iTown / Deck.gl …  
But in the case of Cesium as the Viewer create html GUI and is bound to knockout, it wont work.

I’m struggling as well. I’m trying to use `ol-cesium` which does not expose any `Viewer` object. There are like 0 examples anywhere of using Cesium without Viewer.
