I was sent the attached screen shots by ofer@yeda.co.il

Each word is displayed correctly, but the order of the words is reversed. 
For example the Hebrew equivalent of WHAT'S NEW, which should be rendered

The first thing to try in fixing this is to port the IBMBIDI changes in 
gfx/src/windows/nsRenderingContextWin.cpp to

Attaching new screenshots. For testing I suggest you use the Hebrew testpage 
that Mimi prepared for Andreas, which has text in Hebrew with images of the 
expected rendering.

From dupe:
------- Additional Comments From Simon Montagu 2001-05-18 11:52 -------
What I was trying to say was that the Hebrew in your screenshot has been
ordered with base direction left-to-right instead of right-to-left. In
Windows when mRightToLeftText is true in nsRenderingContextWin.cpp we call
SetTextAlign with TA_RTLREADING, which sets the base direction for the
device context's native reordering to right-to-left. You have to find the
equivalent API for Mac and call it.
------- Additional Comments From Simon Montagu 2001-05-21 15:51 -------
What I meant was the base (paragraph) direction used when the platform invokes 
its own implementation of the Bidi algorithm. This is important, because it 
determines whether a logical text like


is rendered

TGHIRYPOC 2000 TFOSORCIM   <--- with LTR base direction


TFOSORCIM 2000 THGIRYPOC   <--- with RTL base direction

In Windows this is set by calling SetTextAlign with the flag TA_RTLREADING (by 
the way the comment in the source of nsRenderingContextWin.cpp is not 
synchronized with the code -- I'll file a separate bug on that).

I believe the following three patch should fix most mac os hewbrew problem

big endian issue in nsFrame.cpp
see latest patch in http://bugzilla.mozilla.org/show_bug.cgi?id=116976

big endian issue in nsBidiImp.cpp 

turn off hebrew reordering and do not report hint on mac gfx
