enum ARVRInterface_Tracking_status

Tracking is behaving as expected.

Tracking is hindered by excessive motion (the player is moving faster than tracking can keep up).

Tracking is hindered by insufficient features, it's too dark (for camera-based tracking), player is blocked, etc.

We don't know the status of the tracking or this interface does not provide feedback.

Tracking is not functional (camera not plugged in or obscured, lighthouses turned off, etc.).
