Title: Change visibility of tmpV1 and tmpV2 to protected so other classes can

My usecase is that I want to have the camera rotate around the z-axis but found that CameraInputController hardcodes a rotate around the y-axis. I don't really want to copy-paste the entire class so changing tmpV1 and tmpV2 to protected would make it easy to extend and override process() without breaking other methods like update(). It's really a quick-fix but it doesn't seem that bad.
