no but considering kostyas is limited to 4th order and uses fixed coeffs
that really are only correct for specific cutoff freq, i suspect kostyas
will be removed eventually. but until that having 2 in svn is fine

maybe kostyas optimized unrolled 4th order filter function could be
used though in bartlomiejs code (if its faster ...)
