In the future, touchscreen mode should perhaps be a per-device setting,
so I think it makes some sense to have this in GtkScrolledWindow, so the
behavior can be chosen based on the device that's currently interacting
with it.

That's a reasonable usecase, perhaps kinetic scrolling should also obey
the gtk-enable-animations setting.
