Fix incorrect QImage transformation when its devicePixelRatio != 1
QImage::transformed compensates for unwanted translation. This compensation
is performed in "pixel space". However, a possible code path to perform the
transformation uses QPainter which is devicePixelRatio-aware and expects the
transformation matrix to be in logical coordinates.
For example, image.transformed(QTransform().rotate(45)) will result in
cropped out image if devicePixelRatio == 2.
