QWebPage has API for handling QWidgets as views but not for QGraphicsWidgets. We have QWebPage::setPage(QWidget*) and QWebPage::view() which allow us to implement custom web views using any QWidget. We need a way to handle this same use-case for QGraphicsWidgets otherwise we'll keep this inconsistency in our API.
We are moving on and this doesn't make sense anymore... Also QtWebKit1 won't have any API additions AFAIK.
