1. Touch events

    Method of registering when, where and how the interface is touched, for devices with a touch screen. These DOM events are similar to mousedown, mousemove, etc.

  2. element api: `touchstart` event

  3. eventtarget api: addeventlistener: form with `options` object supported (third parameter can be either options or a `boolean`, for backwards compatibility): `options.passive` parameter defaults to `true` for `touchstart` and `touchmove` events
