Lime TextLayout

I just want to know how I can add a TextLayout to the Screen. I cannot find any documentation about Lime. So I try it here.

I am using the babylonhx 3D Renderer, and I want to add some text to display debugging Information.
Or - if I can’t add a TextLayout over the Renderer - it would be ok to at least add a TextLayout to an extra window. But how can I do that?
