Soory I gave the wrong URLs! It's so easy to retrieve the origin of a  
downloaded file in Finders file inspector ..

It works here! Where do you put xunicode.sty that it survives a new  
installation of XeTeX?


Here is some code for XeLaTeXiT.sh that works in some simple cases  
pretty well:

	#!/bin/sh
	jobname=latexit-1
	xelatex -no-pdf -file-line-error -interaction nonstopmode  
${jobname}.tex
	x=`grep Width       ${jobname}.sizes | awk -F\( '{print $1}'`
	y=`grep TotalHeight ${jobname}.sizes | awk -F\( '{print $1}'`
	echo "$x x $y"
	xdv2pdf -p $x,$y -o ${jobname}.pdf ${jobname}.xdv

The TeX source I used is the one Pierre gave here to test the  
BoundingBoxes problem. The problems I've seen tonight appear when you  
set formulae like

	x = r^2 + \sum_{0}^{100} y^2

or

	\frac{\partial}{\partial x} f(x,y) = \frac{\partial}{\partial y}  
f(x,y) = 0

In these cases the height calculated and written to the sizes file are  
only 70 or 60 % of the amount actually needed. There too is a little  
problem with clipping that needs to be corrected in LaTeX. In the above  
cases or in a simple a^2 + b^2 = c^2 the upper regions are cut off, for  
example some pixels in the upper arc of the 2 exponents (this can be  
corrected with \addtolength{\latexitheight}{4.250000 pt} or some other  
value). When I artificially enlarge $y for xdv2pdf it only happens that  
the output window reaches deeper, not changing the clipping, as  
observed in TeXShop. It looks as if LaTeX is missing some (negative)  
offset for this 'window' ...
