It is sometimes the case that the imagery being rectified (warped) has
no GCPs (ground control points) and sometimes we have to resort to
visual inspection and selection of points between images to transform
them. It is also sometimes the case that we have to supplement supplied
GPCs (maybe only the corner and center points are provided) to yield
desired results. This makes heavy use of the primitive GUI (images in
subwindows, zooming, menus, etc).

I expect that. I just want to do it only once. :-)
