Until quite recently the FreeType autohinter did a very bad job on a

with inconsistent perceptual x-height, for instance.
What kind of fonts? Bicameral or other? Display fonts or more normal fonts?
I've mostly noticed it in bicameral Latin serif fonts. It's more
obvious at display sizes but can show up at body-copy sizes as well.
See
http://savannah.nongnu.org/file/quattrocento-irregular-x-height.png?file_id=25578
for an example; according to Werner Lemberg, the autohinter could not
handle fonts whose serif height exceeds an internal threshold.
Unfortunately, that seems to include the bulk of the serif fonts on
Google Web Fonts!
http://savannah.nongnu.org/bugs/?36091 is the whole bug report. It _is_
fixed as of FreeType 2.4.11 -- but it looks like our bundled version is
older than that (2.4.9 according to modules/freetype2/README.moz-patches)
