possibly, there are better ways to do all of these things...

arraysize finds out the size of an array... which was a problem some people has posted to the list and seemed to be missing from pd.

pixfir~ is just another version of the iemlib FIR~ object. I started working on it before I realised that it was already in IEM, but it ended up being faster and more stable anyhow.

pixpow~ is a signal version of the "pow" internal.
