[XeTeX] [OS X TeX] Accented characters in Xe(La)TeX

[njwust at gmail.com]

The faulty display of some characters on top of each other on Mac OS  
looks very much like what I've experienced with my pig latin font  
Entiumgay. In that font, my suspicion was that it's related to the  
numerous AAT glyph insertions and deletions (glyph deletion means  
replacement by the .null glyph).

I don't know whether AAT might be involved with Venturis ADF (it  
shouldn't be, or only very basic AAT).
