This has already been proposed for replaced elements:
  http://www.w3.org/TR/2003/WD-css3-content-20030514/#the-crop
and a more general solution that solves both problems at once (like the
one proposed in [1]) would be vastly preferable to adding a new property
for each property that accepts image values.  For example:

  background-image: image-rect(nextpage.png, 0px, 0px, 10px, 10px);

This value could then be used everywhere images can be used: 'content',
'list-style-image', etc.

Putting multiple images into a single raster image file is a common
technique in user-interface design and would improve the page loading
performance.
