Design
Clutter is a scene graph based canvas working in retained mode. Every object on the scene is usually a 2D surface inside a 3D space.
Clutter abstracts the native windowing environment behind a backend, which is also responsible for creating the main container for the scene graph; this top level container is called the stage. Items on the stage are called actors.
Instead of operating on matrices, as does OpenGL, the Clutter developer changes properties of each actor. Clutter will then notice the changes, and render the scene accordingly.
