If a font has few very large glyphs, the bbox for these large glyphs will be
used for smaller glyphs as well. E.g. the FiguralBookPlain font in
http://www.maps.org/news-letters/v20n2/v20n2-bulletin_full.pdf results in far
too large bboxes for most of the first page's text. To reproduce, just search
that document for text present on the first page in pdfview.
