i think the consensus seems to be that its the responsibility of the
plugin to smooth (interpolate) parameters that may need smoothing,
since only it can know (1) if they need it (2) how best to do it.
what is needed more than anything here is an additional note in
ladspa.h to make sure that plugin authors (of whom there are only a
few right now) understand that they should not use the control port
values as-is unless it is for a parameter that never needs smoothing
(e.g. a switch parameter).
