Animating the icon spring using the `translation-x/y` properties instead of the `x/y` properties avoids relayouts. There are still other non-icon actors moving, but it's a big improvement. Before: 595 relayouts per spring After: 94 relayouts per spring Reducing relayouts reduces reallocation, which reduces CPU-intensive JavaScript execution. https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/926
