I was very much suprised to see that the alimiter filter actually delays
the audio - as in extra samples are inserted in the beginning and some
samples are cut in the end. This trashes A-V sync, so it is a bug IMHO.
So unless somebody has some valid usecase for the legacy way of operation
I'd just simply change it to be "zero delay" without any additional user
option, in a single patch.
