The problem with that approach is that it doesn't degrade gracefully for
browsers without the feature.

We've just landed a feature on Gecko trunk for image values of the form
-moz-image-rect(image.png,0,40,20,20), which does allow graceful
degradation, e.g.
background: url(image-small-05.png);
background: -moz-image-rect(image.png,0,40,20,20);

But we may need to add some other feature to support Alex's use case.
