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

I'm surprised too that it didn't work.  Double check that the stereo 
parameters in the Camera tool are sensible for the journal images (eg., 
the screen width defaults to the width of your monitor, but you would 
want at most the width of the page).
