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.
