[Chimera-users] Cross eyed stereo pair generated by default

Hi Elaine,

Thanks - I am aware of this option, but there seems to be a bug in it -
neither the wall eye nor cross eye modes in camera generate true stereo
pairs - they are flat, with no depth after superposition.

For example, the following image was generated using save as stereo pair
(cross eye):

And the same view via camera mode cross eye stereo:

Interestingly, this is not the case if I save two separate images using
camera mode right eye and camera mode left eye and then assemble them into
a pair myself, so it seems to be specifically a bug pertaining to the
stereo pair camera mode.
