No. You can't get the exact width and height of a glyph at a specific
DPI using the bounding box (to be more precise, if the DPI is smaller
than the font's `units per em' value, used by the font designer to
create the glyph).

Guess what: You have to render the glyph, then you can extract the
width and height from the FT_Bitmap structure.
