it is not bound because there is no C based binding for the X libraries
-- only a Perl reimplementation of the X11 protocol. while sharing might
be possible (though I haven't investigated it) it could lead to weird
results and I don't want to commit myself to support something that I
can't verify as working.
if you provide a patch for the clutter-perl bindings to expose those
methods (under the Clutter::X11 namespace, for instance) and you verify
that they work, then I'll consider pushing it upstream.

yes, because Gtk2::ClutterEmbed uses its own window -- and it does so
internally on two different platforms.
you cannot reuse Gtk2::ClutterEmbed, but you can use the GtkClutterEmbed
code in C and then provide Perl bindings for it.
what you need to do is create a small C library that implements a
subclass of ClutterStage and calls clutter_x11_stage_set_foreign()
inside the realize() virtual function -- after you chained up to the
parent implementation.
then write the Perl bindings using the perl-Glib machinery that
clutter-perl uses, and use the custom class inside your Perl code.
ciao,
Emmanuele.
