This would include several prefs in chrome/common/pref_names.h:
kTapToClickEnabled
kTapDraggingEnabled
kEnableTouchpadThreeFingerClick, and maybe others.
I am also thinking whether ash::TouchDevicesController should rename to ash::InputDevicesController so that it could also take prefs such as mouse-related, scroll-related.
