* The autoRotation behavior (BABYLON.AutoRotationBehavior) is designed to create a smooth rotation of an ArcRotateCamera when there is no user interaction.
* The framing behavior (BABYLON.FramingBehavior) is designed to automatically position an ArcRotateCamera when its target is set to a mesh. It is also useful if you want to prevent the camera to go under a virtual horizontal plane.
* The Universal Camera is the one to choose for first person shooter type games, and works with all the keyboard, mouse, touch and gamepads. This replaces the earlier Free Camera,
* which still works and will still be found in many Playgrounds.
