CompositionTarget is a class that represents the display surface on which your application is being drawn. The WPF animation engine provides many features for creating frame-based animation. However, there are application scenarios in which you need control over rendering on a per frame basis. The CompositionTarget object provides the ability to create custom animations based on a per-frame callback.
