Detailed Description
CameraActor controls a camera.
Allows the developer to use actor semantics to control a camera.
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 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 orientation is ignored, instead the camera looks at TARGET_POSITION in world coordinates.

Initialize it using CameraActor::New(). Calling member functions with an uninitialized CameraActor handle is not allowed.
- Since:
- 3.0, DALi version 1.0.0
Destructor.
This is non-virtual, since derived Handle types must not contain data or virtual methods.
