The problem of line control points is exaggerated because the optimizer
gives more weight to them.
This is new to me. I thought the optimizer treats all cp the same. Can you
give a source? Or give a hint, where in the source code this is implemented?
I went digging through my old emails. In 2004 it use to be that lines distance
were squared. This was an error and corrected. Then there was a discussion off
the email-list about adding a weight to line control points. It got lots of
testing, but it never got implemented. Because it actually caused more problems
than it solved. I have been remembering this wrong for a long time. Sorry for
the confusion.
Optimizer calculates distance with EvaluateControlPointErrorAndComponents() in
adjust.c
