Add a WebGL example?

[bryanbraun]

This would mean using the WebGL 3DContext APIs to render a bouncing ball, without any 3rd party libraries.

I'm not sure what this code would end up looking like. I'm most interested in adding the demo if the code has non-trivial differences to other existing approaches (like canvas, for instance).

Important: this doesn't mean adding a 3D version. Any example using WebGL would need to visually look the same as the existing demos, as described in the contribution guidelines.
