Seagull Correction
Use this correction after the image has been adjusted with top and
bottom bow and keystone. If still a deformation (like a seagull) on top
and bottom of the image is visible, proceed to the seagull correction.
Due to interaction, it is possible that the top and bottom bow have to
be readjusted after adjusting the seagull correction to obtain an
improved image. The default value on the bar scale of this correction
is 50.
