Just a suggestion: as far as I know, there's no "originalEvent" in touches[0] - only in the event itself. This would allow you to reduce these two variables to:

var e = (event.changedTouches && event.changedTouches.length) ? event.changedTouches[0] :
    ((event.touches && event.touches.length) ? event.touches[0] : event;

You're right - thanks for noticing it. I guess I'd just like to get it merged sooner rather than later, and then we can clean it up. Let's see what @mzgol says.

I'd rather you check here for $rootScope.event.{clientX,clientY} as this is what's actually important here. This should still fail without the patch.

BTW, this test will pass even if only touchend is patched. It'd be good to test them both.

This would be a false positive on browserTrigger(element, 'click'), though (which you should test as well as it's patched, too).

@lgalfaso We should most likely just create a Protractor test for such stuff, too much hacking must happen here to test anything.
