Re: tibetan rendering support in ICU

Hello Karunakar,

Jens' analysis looks correct to me. The featureTags variable is a 
pointer to a pointer to a tag, i.e. a pointer to an array of tags, so 
you need the "&" operator.

After a quick glance at your code, I have a few other comments:

* The adjustGlyphPositions() and glyphProcessing() methods look like 
they're the same as the ones which you would inherit from 
OpenTypeLayoutEngine. You can probably just inherit.

* If you have the option, I suggest that you work w/ a newer version of 
ICU - there have been many improvements and bug fixes made to the 
LayoutEngine since ICU 2.2. (We're about to release ICU 3.2!)
