title: Multi-touch gestures in webapp on desktop
body: <p>I'm developing online map(like google maps) of cool fantasy world.  I'm also use OS X on my main computer. Since OS X(especially Lion) are focused on different multi-touch gestures because almost of all mac users have a multi-touch input device(magic mouse or trackpad) I want to add support of pinch gesture to my online map(two-finger scroll would be cool to add too). Is it possible to do it? It's not bad if it will work only in some specific browser or web engine.</p>
