enum ARVRServer_RotationMode

Fully reset the orientation of the HMD. Regardless of what direction the user is looking to in the real world. The user will look dead ahead in the virtual world.

Resets the orientation but keeps the tilt of the device. So if we're looking down, we keep looking down but heading will be reset.

Does not reset the orientation of the HMD, only the position of the player gets centered.
