This happened because w32uniscribe.c didn't reverse the sign of the
y-offsets returned by the Uniscribe shaper. This reversal is
necessary because the Y axes in font definition coordinates and in
Emacs screen coordinates point in opposite directions.
I see that ftfont.c consistently reverses the sign of y-offsets,
probably for the same reason.
Fixed in trunk revision 109876. Please test.
P.S. This bug affected all complex scripts, not just RTL or Arabic.
