Clutter is *not* a tool for 3D modeling software.

the fact that Clutter uses OpenGL and has a 3D canvas doesn't mean that
you can use it for every use case covered by the OpenGL API.

Clutter is the equivalent of CoreAnimation on Quartz; it should be used
to create dynamic and compelling user interfaces - and it should
definitely not be used to create GL viewports inside a GTK+ application.
in fact, if you try to fall back to pure GL it will probably be far less
performant than it would be normally.

ciao,
 Emmanuele.
