Attributing original authorship is good, but pan is a very important filter,
and we should avoid license issues. If the code is completely reimplemented,
then there is no need to contact Anders to relicense it to LGPL, while it is
still possible to credit him for the original work.

Stefano's solution in af_format was to have both set of coefficients, int
and float, and I find it rather good.

I rushed something else to avoid blocking an important feature. Incoming
patch series.
