*
* And perhaps we should always set the zoom even if it was more expensive,
* since DocumentViewerImpl::SetTextZoom claims that child documents can have
* a different text zoom (although it would be unusual), and it implies that
* those child text zooms should get updated when the parent zoom gets set,
* and perhaps the same is true for full zoom
* (although DocumentViewerImpl::SetFullZoom doesn't mention it).
*
* So when we apply new zoom values to the browser, we simply set the zoom.
* We don't check first to see if the new value is the same as the current
* one.
