The page transition in ash::PaginationModel is used to provide
the animation effect on several views in ash, but currently
this is the default gfx::Animation which runs independently from
the compositor.

It would be plausible to run with the compositor by using
AnimationDelegateViews. The use of UnifiedSystemTralModel is
still TODO, so the use of the compositor is still optional.
