Re: [1.2T-LC] i18n comment 9: Geometric middle of the text string

I haven't read the source document, but is it clear whether it is talking
about the text bounding box vs the 'black bit box'. That is, for
"      abcd"

does it put the center between the b and the c, or before the a. In
particular, many characters (esp non-Latin) 'overflow' their bounding box,
or don't take up all of it.
