I've sketched this out using your suggestion above (calculating it once and returning the fraction for the called beam) - nevermind my previous question about redoing calculations. A new patch set is on-line. I still need to do the math for the longer slopes - I'll have time to do that later today or tomorrow. In the spirit of the one-change-per-push idea, I'd like to push the fix to 1504 first before I push the change to feather-direction. Does this seem like a good idea?
