There are two types of camera actor, FREE_LOOK and LOOK_AT_TARGET. By default
the camera actor will be FREE_LOOK.
-A FREE_LOOK camera uses actor's rotation to control where the camera is looking.
+A FREE_LOOK camera uses actor's orientation to control where the camera is looking.
If no additional rotations are specified, the camera looks in the negative Z direction.
-For LOOK_AT_TARGET the actor's rotation is ignored, instead the camera looks at TARGET_POSITION
+For LOOK_AT_TARGET the actor's orientation is ignored, instead the camera looks at TARGET_POSITION
in world coordinates.
