cc: Delay start of scrollbar animation setNeedsRedraw.
This adds a 300ms delay triggered at ScrollEnd in order to avoid
beginning the setNeedsRedraw cycle until we really start fading the
scrollbar, in order to improve performance during non-fling scrolls.
Notes:
- I switched to notifying the animator about ScrollBegin/ScrollEnd when
the currently scrolling layer is attached/detached, and suppress fading
until ScrollEnd.
- The scrollUpdate path is still needed for when the scroll position changes
due to e.g. Javascript, but it's a no-op during a scroll gesture.
- I deleted the pinchGesture logic for simplicity, as there's no
reason to treat pinches differently from scrolls.
- I switches cc::Thread to use TimeDelta for its postDelayedTask since
I ran into some bugs with the flooring to milliseconds. I updated the
few other callers.
