[Paraview] Active Stereo on OS X

[Andreas M. Gerndt]

Mike,

I posted a general solution to the mailing list two weeks ago. Meanwhile, I 
found also a way to modify the parallax by changing the EyeAngle property of 
the active camera. But keep into mind that my solution must be re-compiled 
into Paraview. It works fine with Linux in single display mode. I am not sure 
if this is the way to do that in ParaView. Anyway, this could help your 
friend with his Mac.
