QRasterPixmapData: Reuse underlying QImage in fill() if possible.
When switching from a format without alpha channel to one that has it,
reuse the underlying QImage memory if the old & new color depths match.
This avoids one allocation when using the rather common pattern:
QPixmap pixmap(w, h);
pixmap.fill(Qt::transparent);
