Next stage of RenderPipe refactor: now everything within the pixel was

tackled.

Resulting features:
- render passes
- new pass: Object Index, for masking
- sub-sample alpha masks

Docs:

http://www.blender3d.org/cms/Render_Passes.829.0.html
http://www.blender3d.org/cms/New_Render_features.774.0.html

Note that these changes might mean things to not render fully identical...
For the next days a lot of testing is needed!
