wayland: improve copying of shm buffer with alpha channel and scaling
Painting to image with alpha channel and DPR > 1.0 enters slow path in
"QRasterPaintEngine::drawImage()".
Better performance is achieved when painter's matrix is scaled together
with clipping region instead of scaling the target draw image size.
