[2.1] Correct way to retrieve normals for SSAO

[van4dium]

Hello to all.
I'm trying to do the porting of the demo SSAO but I can not understand
how to get the normal (fill gbuffer) with the new compositor system.

I found online some examples of how to get the normal
from the depth buffer, but no one works well.

Can you tell me the way to having SSAO in OGRE 2.1?

while ago I managed to make this SSAO work with Ogre 2.1 http://blenderartists.org/forum/showthr ... -fast-SSAO it uses only depth and its quite fast. sadly I dropped it because I couldn't make it work with MSAA so I don't have the rest of the code (compositor stuffs mainly) =(, but as far as I remember it was very easy to make it work
