Automatic update from web-platform-tests Move view background offset logic into ViewPainter BackgroundImageGeometry has complex logic for adjusting the background when painting the document element in the view's coordinate space. This logic can be moved into ViewPainter by reusing an existing offset (BackgroundImageGeometry::offset_in_background_). This offset is for the background image itself (similar to the background-position CSS property).
