It will be displayed in the panorama viewer. I probably wont create an extra
vignetting correction preview.

Yes.

The polynomial correction is working, I just have to write the flatfield code,
and add another window for the vignetting coefficents to the lens tab. I won't
add it to the lens tab itself, it is already too crowded.

I have some matlab scripts that estimate the correction polynomial from
overlapping images (which have to be very well registered or contain a scene
with uniform color to avoid high errors). I'll experiment a bit more with the
approach once the correction is implemented.
