Indeed. And a user-preference can set the default weight for both of
them. Some users trust themselves, others trust the computer
better. :-)

Right. Or at least very low.

What I think should be possible is that you optimize the cross
correlation of say a 10x10 area of the image with another image. This
is computationally expensive. This would only be feasable to do for
example for a 5 pixel radius of a point 20 pixels north of a
controlpoint.
I can't think of how to get an initial point to start working from
besides asking the user or doing the feature detection thingy....
But this is WAY beyond addition of an extra field in the
"controlpoint" structure.
