I haven't noticed the shrinkage with crossed viewing (admitedly I choose
the parallel method when given a choice), but I have noticed that with
parallel viewing, the stereo image is noticeably LARGER than either image
alone.  I assume because it's adding the "extra" on each image's edge 
(that the other image doesn't have) onto the composite.

Maybe when one crosses eyes, the path is further so the image looks
smaller?  Doesn't seem like that would do 60% though, unless the
images were real close.
