Clutter and GTK

[Diego Jacobi <jacobidiego gmail com>]

Is it possible to draw all GTK stuff inside a Clutter surface? And the
get the clutter instance from any widget or DrawingArea.

I want to try to develop some widgets with 3D animation (if available)
(like transitions in a tabbed browsing), and i have read that Clutter
cant create more than one Clutter-Gtk per window.

So i am guessing if there is some sort of feature to enable to draw
GTK completely inside of a Clutter window, and the widgets with its
own animation will create its own surface.

If not, maybe there is some method to not create a window with GTK,
and call an event with the image result and then paint it to Clutter.
