Multi-touch support - Pinchable or SqueezableDough()

Multi-touch

This would let you pinch and squeeze the dough from two or more sides, and the dough would droop down out or pile up, away from the forces applied to it, just like real dough. Currently, attempting to pinch the dough or use multi-touch make the dough warp across the screen.

Sounds useful. This sounds like it should be a feature of the PressableDough widget, instead of its own widget. Do you agree?
