It extends the `UiBase` class. Key properties include `oldScale`, `scale`, `viewLeft`, and `viewTop`, representing the previous and current scale, and the visible portion's edges, respectively. The class's constructor creates new instances, and the `toJson()` method encodes the event into JSON format. Its purpose is to inform of changes in what the user see.\n"]]
