Title: pvector use undefined

pvector is normally inside the processing IIFE which puts "undef" in
the signature and doesn't pass it in. Not the case here.

I'd remove it entirely and rewrite the angle math bit from the kinect example, but if we're going to use it this will stop grunt from squawking.
