Does anybody have any comments about this?

An likely alternative would be to have the last two scenes:
    up y   right x*2
and
    up 0.5*y    right x
be equivilent.

That would better mimic the behavior of the perspective camera, where these
two cameras would be equivilent.  This provides better consistency across
camera types, though it does sacrifice some flexibility.

The desired effect (a zoomed-in view of the fisheye lens) could be achieved,
though, by using POV's partial-render capibilities.

Comments?
