Use the source reference distance to specify full panning magnitude

full magnitude, thus providing a smoother transition as it moves around near
the listener

Make the filter history buffer size flexible
...
This lets the filter history buffer be as big as needed for a given use, so
that it can have a size large enough for the more demanding cases, but not be
wasteful for lesser-demanding cases, while not incuring the overhead of an
added pointer indirection
