I see, looks like this is their new approach. They had static images in 
December. It was a rectangular sprite with Facebook logo at the top and 
all other icons on the right and bottom. I specially checked that 
because I was asked to make a comparison of web styling approaches in 
December.

That's my point: nothing to merge! :) The whole sprite merging idea 
comes from having a single sprite. I say:
- use multiple logically grouped sprites
- use API to replace changed icons from other sprites directly in CSS

It is simple and works on every server. Sprite generation using 
ImageMagick/GD may easily fail.
