Sorry, but I am just an end user of the script and do not have enough 
technical knowledge to identify glyph ID, X and Y. I hope that does not 
mean I cannot help you. All I can give you is in layman's terms what 
happens when two characters are in a sequence, such as:

Input (Unicode): Tamil Letter KA + Tamil Vowel Sign E
Output (Glyphs): Vowel Sign E + Letter KA

Input (Unicode): Tamil Letter KA + Tamil Vowel Sign AU
Output (Glyphs): First part of Vowel Sign AU + Letter KA + Second part 
of Vowel Sign AU

(Probably you already have this, but I am just giving examples.)

Will that be sufficient for you geeks to translate into your technical 
language?

And if there is any way I can know the current state of support HarfBuzz 
already has for Indic, I can judge where to start where you left off. Is 
it possible for me to learn this from the code? Which file in 
http://git.gnome.org/cgit/pango/tree/pango/opentype should I look in?
