Last graphic on chapter 14

[supertwist]

Graphic doesn't reflect this:

This patch uses a very slow cycle~ object to alter the value of the frequency cutoff, and
another very slow cycle~ object to later the value of the resonance. You can set the filter
type with an argument (eliminating the need for a filter mode/type umenu, although this
is an option), and the outputs feed directly into a biquad~ object. The result is a sweeping
noise sound that is perfect for your favorite spacey music.
