Well that was interesting, and I had no idea that "getCoalescedEvents()" existed. I've been a little disappointed when trying to write drawing applications before - circles end up looking like polygons unless you add some kind of interpolation. So today we have mouse events, touch events and pointer events. And due to the demands of modern platforms we have things like these passive and cancellable flags. Is there any kind of best practice these days on how to handle user input? As far as I know, iOS doesn't support pointer events (I'm not even sure Chrome was keen on them until recently?) Do I just have to register handlers for all three? Does that affect performance? And is there any way to get pen data into my browser (pressure, tilt, proximity, ...)? I remember this used to be possible with a plugin (eg the Wacom plugin), but I've been disappointed every time I've looked at pointer/touch event pressure values.
