[Blindmath] Another way to use the AudioTac feature in SVGDraw01

[Richard Baldwin]

If the stylus and the drawing pad could stand up to the required pressure,
it should work.

Thanks for the suggestion. Perhaps someone who has a drawing tablet and
some German Film would give it a try and let us know.
