Package lifecycler tracks a window's lifecycle state.

It eliminates sending redundant lifecycle events, ones where the From and To stages are equal. For example, moving a window from one part of the screen to another should not send multiple events from StageVisible to StageVisible, even though the underlying window system's message might only hold the new position, and not whether the window was previously visible.
