btw, what do you people need the "buffer 1" feature for ? i thought of removing it a la long and "replace" it with some controllable feedback in double-buffered mode. (this means: if single-buffered mode is used only to not make "traces" of objects, this could be handled otherwise.) if someone needs full control over the render-chain, removing would probably be a bad idea.
i would hardly wish not to remove it - if it does not break anything otherwise. its a feature and has possibilities - even if "we" do not know at the moment what to do with it
cheers
