Initial browser-side implementation for touch-action
Receive SetTouchAction messages and filter GestureEvents in the browser
based on them.
The logic here so far is pretty trivial, but will get more complex, eg:
- addition of pinch and double-tap gesture handling
- support for pan-x, pan-y, pan-x/y and potentially other touch actions
- more sophisticated handling of multiple fingers (pending WG discussion)
See touch-action design doc at http://goo.gl/KcKbxQ for more details.
Depends on blink-side change in https://codereview.chromium.org/16507017/
