It's for nona and for hugin. We have to get rid of this method of
calculating things as it's really really slow. So the best is just rewriting
it.

The PTOptimizer in asm ? Hum, I think it's easier to just start another one
from scratch. The optimization stage is quite easy if you have the
transformation, it's a standard minimum research function you can find in
the Numerical Recipies.
