Well I would like to print some hires QtQuick output to a printer, because QtQuick can do some nice rendering in an easy way. QtWebkit has gone away (Qt-5.6) and QWebengine is all asynchronous, so you never know, when the rendering is finished (only the DOM loading, which happens some undefined time before the rendering finishes).

Rendering QtQuick at a custom resolution into something invisible, which can render itself into a QPainter or can give me a QImage would be great!
