Title: less jerky camera transitions

The old code is kept and can be activated with the #if for comparison.
Compare jerkyness on a flat map (e.g. LongCat32) since terrain altitude changes adds jerkyness.

I store the start camera state and do the interpolation on the full range (start to wanted).
Some optimization should probably be done, e.g. dont call spring_gettime() if we are not in a camera transition.
