Please note that there exists a "foreground-image" property, just it
has been called "content: url();" (and creates replaced element, to
which the fit property applies).
But there is a subtle difference between images (or general replaced
content, including videos or animations) as content and images used
for decorations. The latter are just part of the background (in the
semantic sense, non in the styling sense) of the element.
Therefore, instead of "foreground-everything", I propose
Property: background-stacking
Value: top | bottom [, [top | bottom] ]*
Initial: bottom

Specifies if the background should be drawn below the content (as now) or above.

The fit properties does not apply to these images, because I don't
think that decorative images should be "letter-boxed" like content
images.
On the other side, we cannot extend "fit" because it does not make
sense to repeat content images: do you display a video twice if the
resolution is too high?
