Nested Scenes
=============

Example of a scene rendered to a texture, which is shown in another scene.

Inception style. Since both the outer and inner scenes are lit, this
may look a bit weird. The faces of the outer cube are like "screens"
on which the subscene is displayed.

The sub-scene is rendered to a texture, and that texture is used for the
surface of the cube in the outer scene.
