In other words, a call to Channel::frameDraw is the only sure sign, that the
node needs the scene database (or not)?
I could implement it that way, but it wouldn't feel good :-) It would shift
a part of the setup process outside of the setup of the nodes.
I thought about introducing a certain naming scheme for nodes, so each node
could identify its role at the time of initialization... what do you think
about that?

Thanks, will try this!
