Comment(by pguyot at kallisys.net):

 There was a bug in my core_text patch for pango. I attached the new one
 (patch-pango-coretext.diff). I did put -ascent instead of descent.

 I checked with a small program (test_coretext.m) that ATS and CoreText
 return the same values for all the functions used in the patch (I tested
 with LucidaGrande and GillSans fonts).

 However, this still isn't perfect (see pango-core_text-2.png). I cannot
 figure out why the lines height differ, or why the patched pango does not
 handle as well as the ATS pango unicode text (see the Greek sample) or
 rendering of ligatures (fi). It might be a problem with cairo.

 Maybe it's time to transmit this issue upstream...
