public void setTrailingRotationInertia(float trailingRotationInertia) {
        this.trailingRotationInertia = trailingRotationInertia;
    }
Sets the trailing rotation inertia : default is 0.1. This causes the camera to stop roughly when the target stops moving
before the camera reaches the trail position.
Only has an effect if smoothMotion is set to true and trailing is enabled

@param trailingRotationInertia the desired value (default=0.05)
