I suggest that the more common case should be directly supported by the API
and the unusual case require additional work within the application. If we
return the 'height' as a distance normal (in user space) to the font
baseline, then the user can do whatever they want with it, I don't think 
we're losing any information here.

This definition has the added advantage of requiring no changes as the 
code happens to work that way already...
