This one is essential: it will allow some fundamental optimizations,
in particular in {SMALL,}ICON modes, which are just brutal right now.
It introduces the notion of a item iterator; it's really neat, IMO.
Next will be the optimizations I was talking about, on top of this one.
ChangeLog
Introduce the notion of item iterators, and use them to clean up code.
