horizontal only? #215

I don’t think it’s possible to have a drag or zoom behavior that works only horizontally and doesn’t “trap” the natural vertical scrolling gesture?

Not the same issue, since the difficulty here is not about applying only t.x. It's more about reading horizontal scroll, but leaving the natural vertical scroll to the browser.

hammerjs does it this way: https://github.com/hammerjs/hammer.js/blob/master/src/touchactionjs/touchaction-constructor.js#L109
