Add an effects chapter which gives a broad overview of the abstract classes in the effects API, plus a short example of how to apply one of the stock Clutter effects (ClutterColorizeEffect). The recipe explains how to create a custom ClutterDeformEffect to produce a page fold (code based on ClutterPageTurnEffect). The example code includes the effect class plus a small application to apply it to a texture.
