        Spins the view around the given axis when a change happens.

        - Parameters:
            - `axis`: The x, y and z elements that specify the axis of rotation.
            - `anchor`: The location with a default of center that defines a point in 3D space about which the rotation is anchored.
            - `anchorZ`: The location with a default of 0 that defines a point in 3D space about which the rotation is anchored.
            - `perspective`: The relative vanishing point with a default of 1 / 6 for this rotation.
            - `rate`: How fast the the view spins.
