Comment #12 on issue 617 by n.puttock: X-offset works in a specific way for  
RehearsalMarks

I was hoping James's patch would sit there for a while longer (at least  
until I had chance to review it. :)

I still think the best option is to follow my advice in comment #3.  Users  
shouldn't be overriding X-offset unless they're familiar with the IR and  
the consequences of removing the default callback.
