The following code:
QTransform result;
qDebug() << QTransform::quadToQuad(QRectF(0,0,1,1), QRectF(0,0,1,1), result);
outputs "false".
The reason is that QPolygonF::QPolygonF(const QRectF&) creates a polygon with 5 points, repeating the first, and quadToQuad only accepts polygons with four points.
You can work around it by creating the polygons yourself, but that is significantly more verbose.
