[XeTeX] XeTeX release 0.84 available

[Jonathan Kew]

I have posted a new release of XeTeX in both i-Package and Apple 
Installer formats; see:

	http://scripts.sil.org/xetex

or my directory within i-Installer.

Version 0.84 includes a fix in the OpenType font handling that should 
make fully-voweled Arabic text work without the words jumping around on 
the page! (Other fonts could potentially be affected, too.)

It also includes new primitives that make it possible to query an 
OpenType font to discover the available layout feature tags and 
supported scripts/languages. There is no documentation of these at this 
point, but a new file in the Sample Files archive demonstrates their 
use. (These features are intended only for technically-inclined users 
anyway <grin>!)
