Proof of Concept for 3D Support (Primitives, Scene management) on Opengl backends

[GoogleCodeExporter]

Support for loading, rendering and managing 3D scenes.

I think of primitives like (mesh, material, models, etc) which can be 
organizised in some sort of scene management.

To see how it performs this should be a simple proof of concept to work on 
which does not include support for all backends. However it should be designed 
with multiple backends (Stage3D) in mind.
