[PD] algorithms for drawing filter response curves

[Mike Moser-Booth]

I don't know if this is what you're asking, but iirc it's really just
a matter of substituting exp(j*2*pi*fc/Fs) for z in the transfer
function. I can send a Pd patch illustrating it later, if you like.

I've gotten the GUI interaction working well, now I'm looking for the algorithms for generating a plot of the frequency response of a given set of biquad coefficents?  It'll end up being Tcl, but I can easily read C, Csound, Java, Perl, Python, etc.
