#2903

It may help to emulate more touchscreen gesture.

[PupilTong]

Expose the dispatchTouch related CDP methods may help too I guess

[dgozman]

@PupilTong So, are you after testing touch gestures? Then we should close this in favor of #2903. If you have a different scenario in mind, please explain in more details.
