[XeTeX] Tracking and macrons

[Peter Baker]

The difference between Gentium and Junicode (and probably Bembo Book 
too) is that Gentium has no OpenType features while Junicode does. 
Probably something in the generated code is defeating the OpenType 
feature that applies the macrons. What happens if you use the Unicode 
pre-composed vowel+macron characters instead of the LaTeX \= codes?
