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

Hi, I think I figured it out - it only happens when the projection mode is
set to orthographic (which is what I typically use).
Using projection orthographic, cross eye stereo generates depthless pairs
for the stereo pair mode, but correctly generatres the individual images if
set to stereo right eye/stereo left eye.
