Following design decision, we want to animate AllView and FrequentView when opening and closing with a swarm spring form. This involves a few changes needed to allow that, since from some time now, we are animating page changes in viewSelector, using only a fade transition. However now we want to let appDisplay and iconGrid apply its own animation. For that we special case the change to and from apps page on viewSelector to let appDisplay to animate its own items, using and API on appDisplay which at the same time uses an API on iconGrid. Thanks Florian Müllner for the debugging work https://bugzilla.gnome.org/show_bug.cgi?id=734726
