[PD] analogue clipping

[Georg Holzmann]

Hallo!

> quick tanh looks good.  i put in a dollar and my cpu gave me 96 cents change!

I did not follow the whole thread, so maybe this was already said.

But I would also do the tanh interpolation with a wavetable.
You can simply once use this function to generate the wavetable and then 
use it and it will be very fast (and you can use any function you want) 
- so you can also draw a little bit around, which might be interesting 
too ...
