This is IMO not a question of either or - both GIL and Vigra have spots
where they shine, and areas where they could learn from the other lib.

What if you need to revert your design, because certain functionality is 
not (or not easily) implementable - and you only find out while doing
that one, specific algorithm? So, seeing a lib with lots of
(algorithmic) functionality kind of increases my confidence that the
basic design is sound...

To repeat: I'd at least like to have Vigra's concept of pixel accessors
and promotion traits merged/applied in GIL.
