CSS's background-size and nothing more: a length or 'auto' per axis, or
'cover' and 'contain' which scale to the box. There is no 'fill',
'none' or 'scale-down' — those belong to object-fit, which is a
different property on a different kind of node.
A bare value sizes the width and leaves the height to the picture's own
proportions, which is v1's reading of size: 12.
How big each tile of a background image is drawn.
