QSGSoftwarePixmapRenderer: Fix incorrect background coordinates
The pixmap renderer sets up QPainter's window coordinates system but still
positions the background node in device coordinates. If the window rectangle is
QRect(x, y, w, h) then the background rectangle will be set to QRect(0, 0, w,
h). As the rendering output is clipped to the background rectangle, this means
that the image will be left with transparent bands of x pixels on the right and
y pixels on the bottom.
Task-number: QTBUG-62867
