Zoom (JxBrowser 7.17 API)

```
public interface Zoom
```
Allows zooming content of a web page.
A Zoom instance belongs to a Browser instance and can be used only if the Browser instance is alive. When the Browser instance is closed, the Zoom instance automatically updates its internal state and does not allow modifying zoom anymore. The IllegalStateException will be thrown in this case.
The zoom level is configured for each domain separately, so if you set zoom level for the a.com web page, it will not be applied for the b.com web page. If you change zoom level for one domain and then load another one, then the zoom level for another domain will be default.
The zoom level per domain configurations are kept by the Engine instance and they are preserved after closing a Browser the Zoom instance belongs to.
