It's not just about drawing. It's about drawing with clutter in 3
dimensions ;-)

I have disabled the clutter deps for now. You can try the latest git.

If you don't have the latest gnome/gtk+ then you probably don't have the
lastest clutter either.

On Debian I had to enable the experimental repo to pull in the latest
