<br></div><div style> Currently weston's scenegraph ties the geometry information (location on screen, rotation, etc.) to the surface so a surface can only be in one location at a time. This makes it impossible to implement window previews for things like mini desktops and switchers. It is also a problem for my fullscreen shell implementation (it has to be able to clone things). Views simply splits this information apart in the scenegraph so the scenegrapn can contain any number of views which actually correspond to the exact same surface data.</div>
