Easing functions

When declaring animations with WPF, we are able to utilize a powerful capability that helps us to define more specialized animations. While we normally provide a start and end value for our animations and let WPF interpolate the intermediate values, there is a way that we can affect this interpolation process.

There are a number of mathematical functions that provide complex animation paths and are known as easing functions. For example, these can accurately replicate the movement of a spring, or the bounce of a ball.

We can simply declare the appropriate easing function within the EasingFunction property of the animation. Each easing function extends the EasingFunctionBase class and has its own specific properties. For example, the BounceEase element provides Bounces and Bounciness properties, while the ElasticEase class declare the Oscillations and Springiness properties.

All easing functions inherit the EasingMode property from the base class. This property is of the enumeration...
