Each state can still have its own separate input handler, root node, ... I don't use any entity component system as it is overkill in my case. When you move from one state to another one, you can clean your mess and install the state-specific objects. I would rather separate the concerns by putting the different sets of controls into different classes if I were you.

Yes, it's better because if you pass a GL object to a method, it's not obvious that the receiver is executed on a thread on which the OpenGL context is current and you're not sure that the GL instance is still valid. If you follow my advise, in the worst case you'll get a clear GL exception telling you that there is no current OpenGL context on this thread.

You can still use different root nodes and different rendering methods for your states.
