Fix T45234: Stereo Parallel vs. Off-Axis 

Parallel rendering was not working.

The idea of having parallel convergence mode to render as parallel but
visualize as off-axis was good, but it was leading to some complications
in the code.

I think it's more clear to the user if parallel looks and render as
parallel, and if she wants to pre-visualize the converged planes, simply
temporarily set the camera to off-axis.
