/// Animates from the *Thickness* value of the previous key frame to its own *Value* using linear

/// This class is used as part of a ThicknessKeyFrameCollection in conjunction with a
/// ThicknessAnimationUsingKeyFrames to animate a Thickness property value along a set of key frames.
///
/// A key frame defines a segment of the ThicknessAnimationUsingKeyFrames to which it belongs. Each
/// key frame has a target Value and a KeyTime. The KeyTime specifies the time at which the key
/// frame's Value should be reached. A key frame animates from the target value of the previous key
/// frame to its own target value. It starts when the previous key frame ends and ends when its own
/// key time is reached.
///
/// Linear key frames like LinearThicknessKeyFrame create a smooth, linear interpolation between
/// values.
