Sprites are a terrible hack.  CSS shouldn't make any attempt to
support them.  CSS sprites should be obviated, for preference, by
browsers loading all images simultaneously, negating the performance
advantage of sprites.  (Possibly only if the server requests this
somehow, if causing server load is an issue.)  There is no possible
justification for trying to support an interface where authors are
supposed to manually concatenate images and manually specify offsets
in CSS rather than treating the images as the logically separate units
they actually are.  CSS sprites might be useful now, but that's a bad
situation, not one that anyone should be trying to perpetuate.
