[chimerax-users] 3D stereo lighting is not the same as mono

[Tom Goddard]

Try "camera sbs" and see if shadows look right.  If they do look ok, but stereo does not then it will require some debugging with a stereo system that reproduces the problem and I am not able to test that until quarantine is over.
