Yes it is, but not in Fribidi. Bidi ordering and Glyph shaping can be viewed as
two different layers of treatment. Besides, adding shaping to fribidi is
reinventing the wheel as Pango which relies (relied?) on Fribidi already does it
(and yes, Pango is toolkit independant, even though the fact gnome/gtk relies on
it could mistake people into thinking otherwise). Pango should be considered the
standard (for non QT based apps) unless you have good reasons to think it's
unsuitable and the work should be redone.

Inclusion of pango in such cases would include in the same step fribidi. In any
case, inclusion of two libraries amounts pretty much to inclusion of one, so if
any author is open to inclusion of an additional library it wouldn't be a
problem whether you are in fact talking about fribidi, pango or both. The
linking process only requires indicating which libraries you're using, and
there's no mention of libraries at the code level.
