true (i checked now :-))

i don't think so.
it was my fault.
but i guess most of ggee's filter externals can be rewritten as
abstractions (i checked only [highshelf] and i haven't seen anything you
cannot do with plain pd.)
the only problems that might occur are about precision (as you can only
use single precision in abstractions), but at least highshelf.c uses
single precision too, so that should be ok.
