Generic 3D Object Descriptions

The Evas_Canvas3D_Object structure is an abstract base for other Evas 3D objects (scenes, nodes, lights, meshes, textures, and materials) with reference counting and propagation of modifications via reference tracking. This permits, for example, when a scene object is modified (marked dirty), a number of image objects rendering that object to be notified to update themselves, without needing to call update functions manually.
