+/**
+ * Controls the animation of swiping back and returning to launcher.
+ *
+ * This is a two part animation. The first part is an animation that tracks gesture location to
+ * scale and move the leaving app window. Once the gesture is committed, the second part takes over
+ * the app window and plays the rest of app close transitions in one go.
+ *
+ * This animation is used only for apps that enable back dispatching via
+ * {@link android.view.OnBackInvokedDispatcher}. The controller registers
+ * an {@link IOnBackInvokedCallback} with WM Shell and receives back dispatches when a back
+ * navigation to launcher starts.
+ *
+ * Apps using the legacy back dispatching will keep triggering the WALLPAPER_OPEN remote
+ * transition registered in {@link QuickstepTransitionManager}.
