Using ApplicationContext.DisplayHost.setScale() is the right way to do this. Going to add some Javadoc to help with understanding this use case.

> Zooming UI at program start wents right but all buttons responds from wrong locations (as if the zoom/scale factor would still be the default 1.0).
> This effect can be easily tested with ApachePivot org.apache.pivot.demos.text.TextPaneDemo
> by adding ScaleDecorator & setScale before window.open(display) call like this:
>     ....
>         final ScaleDecorator sd = new ScaleDecorator();
>         window.getDecorators().add( sd );
>         sd.setHorizontalAlignment( HorizontalAlignment.LEFT );
>         sd.setVerticalAlignment( VerticalAlignment.TOP );
>         sd.setScale( 2.0f );
>         sd.update();
>         window.open(display);
>         textPane.requestFocus();
>     }
> The program UI will scale correctly the but buttons will react from wrong locations.
> There is a issue report in the pivot-user mailing list archives: March 2015 with the same header as well with more information.
