[PD] default [output~] in Pd-extended

[Steffen Juul]

To cut a longer story short:

- No i don't want everyone to live there life linearly. How could  
that at all be assumed. (I rather embrace the opposite.)

- The Pd tutorials that Miller ship with Pd is bottom-up. That is the  
didactic contract with the reader. So if you want a canvas'ified-gui- 
volume-control with such use of canvas with graph-on-parent, it need  
be introduced first. That could be done in the "2.control.examples"  
section.
