[XeTeX] Syriac in Polyglossia

[Sargon Hasso]

Thank you very much! I can't thank you enough and you are right it does
improve the output greatly.
There was one glitch however and I was able to figure it out and fix it
rather easily (with little insight). The kashida was slightly misplaced
between characters above the base line with fonts I am using with dramatic
effects. I changed this line:
\def\kashida{\zwj\nobreak \setbox0=\hbox{\ksh}%
   \leaders\hrule height\ht0 \hskip0pt plus 0.5em \zwj}
to
\def\kashida{\zwj\nobreak \setbox0=\hbox{\ksh}%
   \leaders\hrule height\ht0 \hskip0pt plus 0.0em \zwj}
(\hskip0pt plus 0em from \hskip0pt plus 0.5em)
(see attached image before and after).
And yes I thank Vafa too because she sent me a code the other day to reverse
a 2-column syriac document from her xpersian package.

Thanks,
Sargon
