Just remembered a few things: you would likely use interpret-markup to
turn your markup (this does not need to be a string, though that's the
simplest case) into a stencil, and then use
(ly:stencil-extent sten X) to get the X extent of the stencil (likely an
interval).  There are probably C++ interfaces for that as well.
