Fixed fillRect on QImage::Format_ARGB32 images.
With composition mode set to QPainter::CompositionMode_Source, the
raster paint engine's fillRect function filled images which had
non-premultiplied format with premultiplied colours. This was fixed by
converting the premultiplied colour back to non-premultiplied before
writing to the image.
Task-number: QTBUG-5189
