I forgot to mention, Ogre samples are working.
I have managed to make it work. Really I was making other "unrelated" changed when it worked (partially). Now I have the image displaced on the widget. Maybe a problem of viewpoint? I'll start playing with the camera and viewpoint tomorrow.

 Do the Ogre demos work with the G33? Because there's currently a bug in
Ogre which causes problems with the Intel X3100 (mobile version of the
G33/3100); so you probably need to be careful that you're actually
reproducing the Gazebo bug and not encountering an Ogre bug.

See: http://www.ogre3d.org/phpBB2/viewtopic.php?t=36249 for further
details.

 Cheers,
 Mike.
