should this be moved to ShowAnimationFinished?

[please use gerrit instead, 2015/01/02 20:41:28]

ShowAnimationFinished() triggers ScrollFocusedElementIntoView event. I've added
hooks to listen to that event in
RenderViewImpl::DidCompletePageScaleAnimation():

   // If the controller is in the process of hiding the keyboard, do not log
   // the stat here since the keyboard will not actually be shown.
