Thanks for the great library. I was trying to go-through the source and I have couple of questions.One, on line 135:<p><a href="https://github.com/hyperapp/hyperapp/blob/master/src/app.js#L135" rel="nofollow">https://github.com/hyperapp/hyperapp/blob/master/src/app.js#...</a><p>You seems to be attaching global event handler. Looks like we can't have multiple event handlers at this time. Is this expected or it would be handled in the future?<p>2. Why do we use requestAnimationFrame for rendering? Do you think its going to offer best performance all the time? Note here, I'm new to requestAnimationFrame concept, so you can answer me like I'm a noob :)
