Synthetic pinch-to-zoom gesture.
Add implementation of synthetic pinch-to-zoom gesture, exposed in JavaScript
through chrome.gpuBenchmarking.pinchBy().
A pinch gesture is defined by four parameters:
1) whether to zoom in or out,
2) the number of pixels to cover during the gesture,
3,4) the x/y coordinates of the anchor point of the gesture.
