sorry, I don't have the time to look into the details of your code right now.
But in general FBO support is much better in OpenSG 2. What you're trying to do
is probably pretty simple based on Carsten's Deferred Shading framework, which
has to do post-processing anyway.
Carsten, can you comment a little bit on this one?
