swr: move compensation_distance handling to swri_resample caller.
I think there's an off-by-one in terms of the switchpoint where we switch from dst_incr to ideal_dst_incr, I don't think that's a massive issue, but just be aware of that. It's probably trivial to prevent but I don't care. Signed-off-by: Michael Niedermayer <michaelni@gmx.at> I could not reproduce any off by 1 error, results are bit exact (michael)
