[OS X TeX] Scaling xipa font

[Stephen Anderson]

I use the tipa phonetic font (actually xipa) together with various ps 
fonts: Latin Modern, and two (AdobeGaramongPro and AdobeWarnockPro) 
that I made from otf files. I finally figured out how to get slanted, 
etc. variants of tipa in such documents, by making a "t3lmr.fd" file 
(for Latin Modern) based on "t3ptm.fd".

The xipa variants of tipa are generally OK together with the other 
fonts in question, and I'm certainly not going to try to design 
versions more like "Latin Modern" or "Adobe Garamond Pro".  But one 
thing I would like to fix: the xipa font is a bit too big, and I'd like 
to scale it by a factor of about .9 or so.  I know you can scale 
Helvetica for use as the sans serif font together with others by 
invoking it with "\usepackage[scale=.92]{helvet}" but the tipa package 
doesn't understand that option.  I can't really figure out how to get 
tipa.sty to work like helvet.sty in this regard - the relevant code at 
the top of helvet.sty clearly does it, but it's too obscure for me.

Can anyone help me solve this?

Thanks,
