Using Ogre3D’s OpenGL renderer with the Oculus Rift SDK

Hello there!
The process of getting a scene rendered by Ogre to the Oculus Rift is a bit envolved process. With a basic conaissance of Ogre, and trials and error while browsing the Ogre wiki, Documentation and source code itself I got the thing runing each time Oculus changed the way it worked.
Since we are in the version 0.8 of the SDK, and that 1.0 will come with probably not much change in this front, I think I can write some sort of guide, while browing my Ogre powered VR game engine, and tell you the story of how it works, step by step.

I’ll paste here some code with explaination. It’s not structured into classes because I don’t know how you want to do. I don’t use the Ogre Application framework because I want to choose myself the order where things happen
