Very good!

But it should still work for a rectilinear output, otherwise it wouldn't 
make any sense to use the straight line control points, right?

I have a calibration photo (part of an office building) for my Oly C8080 
with a lot of horizontal and vertical lines in it.

I entered a few vertical lines, a few horizontal, plus a bunch of 
straight lines.

Both the new and the old optimizer have really _big_ problems trying to 
find a stable solution for the lens distortion parameters. (At maximum 
wide angle this camera/lens have significant gullwing style distortion, 
with barrel that flattens out towards pincussion nearer to the corners).

Should I place the photo + my current PTAsm project file on a web server 
for download?
