// .NAME vtkPlaybackRepresentation - represent the vtkPlaybackWidget
// .SECTION Description
// This class is used to represent the vtkPlaybackWidget. Besides defining
// geometry, this class defines a series of virtual method stubs that are
// meant to be subclassed by applications for controlling playback.
