This GUI element appears when zoom function is activated, otherwise it will disappear from user's view. This gauge show current camera zoom position and labels that represent different states. When pointer will reach some-mode label, mode will be switched. So rollback from 3D mode to switch to 2.5D mode (with any table selected). And rollback from 2.5D mode to switch to 2D mode.
