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.

Famous quotes containing the word design:
“What but design of darkness to appall?—
If design govern in a thing so small.”
—Robert Frost (1874–1963)
“With wonderful art he grinds into paint for his picture all his moods and experiences, so that all his forces may be brought to the encounter. Apparently writing without a particular design or responsibility, setting down his soliloquies from time to time, taking advantage of all his humors, when at length the hour comes to declare himself, he puts down in plain English, without quotation marks, what he, Thomas Carlyle, is ready to defend in the face of the world.”
—Henry David Thoreau (1817–1862)
“For I choose that my remembrances of him should be pleasing, affecting, religious. I will love him as a glorified friend, after the free way of friendship, and not pay him a stiff sign of respect, as men do to those whom they fear. A passage read from his discourses, a moving provocation to works like his, any act or meeting which tends to awaken a pure thought, a flow of love, an original design of virtue, I call a worthy, a true commemoration.”
—Ralph Waldo Emerson (1803–1882)
