This feels quite a bit slower than the non-QtQuick version. This makes sense, as there is an additional level of indirection. Instead of painting directly, we paint into an QImage and turn that into a QSGTexture. Ultimately one would think that we should render directly using QtQuick. Alas, we can't, since that would mean no more printing/ exporting of profiles. How sad. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
