I agree that it would be useful, but I think it would also be useful for  
normal in-page navigations, e.g. when there is a position:fixed header.  
Would it be better to start with a CSS property to control scroll offsets,  
and see if it's still necessary to add something more to scrollIntoView?

Yeah, that was discussed in some other thread and I hope to put it in the  
spec soon.
