The relation between the font size and the text height is determined by 
the font designer; usually, the given size is the *smallest* line height 
you will want to use for the font you get back.  See Ned's post for a 
link to a more complete discussion.

There's no code for this in current PIL releases.

The following module might help; it's a work-in-progress for AggDraw, 
but should be fairly easy to adapt to both PIL and your requirements:
