rotate_cam example

@JohnSumskas hi, what is the https://github.com/kivy/kivy3/blob/development/examples/rotate_cam.py example supposed to demonstrate?

[JohnSumskas]

Its meant to be a simple example of the Orbit Control Widget. I.E being able to orbit and move around an object using the right and left click buttons or touch controls.

So i better rename it to orbit.py or similar?

This leads me to another question. The several versions of ObjectTrackball widgets in the examples. Are these the predecessors of the OrbitControlWidget?

[JohnSumskas]

Yes that is correct. But if I recall, Object trackball operated differently. Things got a bit messy on my side when this was a private repo.

Yes, I'd agree, renaming it to orbit.py would be more appropriate.

Thanks for the information
