After we merged the new GpuBenchmarking::SmoothScrollByXY, which has two
delta values, for vertical and horizontal scroll deltas, we should this
new function for all the scroll functions in resources/gesture-util.js.
So here we change wheelTick function to take deltaX and deltaY instead
of one delta and direction values, so now scroll deltaX and deltaY can
be different values.
