This friend has now pointed out that the distortion of images handled by the
visual cortex (and not just the retina) is even more marked than suggested:
".. you kind of left out what I thought was most important in my previous
reply, but this page shows several links regarding this topic. Things are
even more distorted past V1.

The following figure (Connolly and Van Essen 1984) shows the mapping of the
visual field (A) on the LGN (B) and the striate cortex (C) in monkey. Note
that the representation of the central 5 degrees (shaded areas) in the
visual field occupies about 40 % of the cortex. "
I'm disappointed that you guys, especially Bob M, aren/t responding to
this. It just might be important to how the brain succeeds in perceiving
images, while computers are such a failure.
