That makes sense.

The way I had it explained to me what the transform does is that you take 
the polygon described as (x,y) pairs, and what the transform gives you back 
is the a_n in the a_0*x^0 + a_1*x^1 + a_2*x^2 = 0 formula. That's why I 
could never figure out how it was picking out frequencies and such.
