2d graphics effects 101: throwing something
I have a page in my desktop app, and I've implemented simple grab-and-pan.  It works great.

When you are panning in this way and you are release, the page stops dead where you dropped it.

I'd like it to continue slightly with some momentum, and stop eventually.  Rather like the 'throw' in the iPhone UI, I guess.

I'm not really chasing perfection, just a very crude simple sense of being able to 'throw' that page.
