خالد حسني أَنَا الّذِي نَظَرَ الأَعْمَى إِلَى أَدَبِي وَأَسْمَعَتْ كَلِمَاتِي مَنْ بِهِ صَمَمُ

First attempts of Arabic math typesetting. Using ConTeXt MkIV, LuaTeX and my experimental XITS Math font.

I was trying to change the math font used in plain TeX (as opposed to LaTeX or ConTeXt), but I didn't seem to find it documented any where, apparently it is so obvious for TeXperts to be even documented. Anyway, I figured it out and I'm documenting it here so I don't have to search it again.

Set font families 0-3 to the new font, as follows:
0: math text ("sin", "cos", numbers, etc.)
1: math italic ("x", "y", "z", etc. don't have to be italic at all e.g. Euler)
2: math symbols
3: math extensions
\textfont: normal size font
\scriptfont: font for sub/super script

Scribus 1.3.5 (not released yet), has support for using TeX for text rendering via a special LaTeX frame.

I grabbed it from svn, built it, some quick configuration to use xelatex instead of pdflatex, and the result is the screenshot above :).

Now, I need to polish this and make a good configuration file for ArabXeTeX (that I'm using on top of XeTeX engine).
