I'm not sure this will help you specifically with transforms, but it may
give you some ideas about how to give a user some control over the camera.
If not, at least Naomi got you on the right track on dealing with
transforms. I agree, they are tricky to figure out the first time around.
The tree stuff is superfluous, just dig out the camera behavior...
