Hiding VRayStereoscopic helperturns off stereo render

[jordanw]

Rendering with the VRayStereoscopic hidden disables the stereo rendering. Is this supposed to happen? It seems like a bug to me as you have the enabled checkbox to control weather the stereo works or not.
The whole enable stereo with a helper seems like a strange work flow to me too. Why not implement it as part of the camera rollout in the render settings? Would you ever want to have two helpers in your scene?
If there is any logical benefits to it being a helper I would love to hear!
