[OS X TeX] LaTeXiT 1.4.0 released

There may be bugs, but the code you point out is correct :-)
The awk script I use to compute the BBox works well. Not better than  
yours, but it works.

Xelatex is the culprit for the bounding box problem.

Let's forget LaTeXiT and consider the following document: it  
generates a tight pdf when processed with pdflatex. If you process it  
with xelatex, you'll get a full page PDF document : no tight bbox.

However, if I try to compute the BBox of this document with gs, it  
seems that gs is smart enough to compute a good one. So, it seems  
that there is a dysfunctionality in xelatex regarding the bbox that  
it indicates when writing the pdf file.

Pierre
