Sorry, i didn't make myself clear.
First of all, this is a draft (i should've marked it patch-needs_work).
Secondly - yes, this will help solving 3 gsoc-lyrics issues.  But it
will also help with other things, and i'm pretty sure that a lot of
objects will benefit from having both extents and core-extents.
Please take a look at
http://lists.gnu.org/archive/html/lilypond-devel/2012-06/msg00230.html
- it shows an example of how markups will benefit.
I will elaborate and send more examples later today.

thanks for a good question!
