Yeah, I installed the Hebrew translations and can confirm that launching a Qt app 
with the LANGUAGE and LANG variables set accordingly does the trick, at least 
for menus Qt renders entirely itself.
The good news is that means one doesn't have to set one's desktop to become 
incomprehensible, but it'd still be nice to have a set of en_Mirror translation 
files :)

You mean that the text drawing routine would normally obtain additional 
information from the text itself whether it should be rendered differently from 
the global layout direction? Wouldn't that affect native Mac apps to?
