Chapter 7 Key Frame Effects
This section gives an overview of key frames, and describes the
operations required.
A key frame is a set of data which determines the instantaneous
pattern of an effect during a transition.
An effect, in turn, is obtained from a sequence of key frames,
interpolated along the time axis so as to appear continuous.
