W3C has a Media Fragments WG, maybe that's a better place to discuss 
sprites. CSS doesn't seem the right place to define how to refer to 
fragments of external resources. E.g., if sub-images are useful in CSS, 
then how about in SMIL, SVG, or HTML? For example:

    <img src="foo.png#xywh=12,20,10,10" alt=...>

(This syntax is one of the proposals under discussion. See 
http://www.w3.org/TR/2009/WD-media-frags-reqs-20090430/#naming-space 
for details.)

The mailing list of the Media Fragments WG is 
<public-media-fragment@w3.org>
