From the ticket: "The result is now still too wide, but that is truly cambria's fault: the integrals have large italic corrections while in fact they fit in their bounding boxes."
This isn't Cambria's fault per se, as any font that is to be used with MS Office as well is going Cambria's route (so does Asana Math and my two math fonts.)
So, IMHO this should be the default behaviour for new math fonts, and old TeX fonts pretending to be new math fonts should compensate for this, not the other way around.
I am not quite convinced yet. The MATH spec seems to disagree with both the font metrics and the actual behavior of Word. What would happen is Word 2010 (say) fixes that? AFAICS, the only reason for Asana being like Cambria is that it copies the font literally instead of the looking at the spec. One thing I could possibly do is to auto-correct in the engine if there is a big difference between width+italic correction and actual glyph bounding box. Best wishes, Taco
