It's used in the context of Chrome OS, where basically chrome is one full-
screen process (think eglfs) and each "app" is just another instance of the 
render process. In that context aura becomes a compositing window manager, 
although not in the traditional sense.

When Chrome is used as browser app, then Aura composites the individual render 
processes in the app window.

What's interesting is that the render process itself doesn't do any graphics 
apart from software rasterization. Any GL processing is delegated through a 
"virtual GL" implementation to the GPU process (which is really the entity 
that does the compositing).
