This patch provides an overall simpler *and* more consistent way of handling the `viewport` parameter during printing of XFA forms, since it's now again guaranteed to always be an instance of `PageViewport`. Furthermore, for anyone attempting to e.g. implement custom printing of XFA forms this probably cannot hurt either.
