class Rabbit::Renderer::SceneWidget

This is not a real widget. This is just a wrapper to enforce our conventions:

* We need to use real x,y not logical x,y for widget location
* We need to adjust margin of rendering area (not element's margin)
  for GTK widget
* We need to use real w,h not logical w,h for GTK widget size
