/**
* @class vtkAffineRepresentation
* @brief abstract class for representing affine transformation widgets
*
* This class defines an API for affine transformation widget
* representations. These representations interact with vtkAffineWidget. The
* basic functionality of the affine representation is to maintain a
* transformation matrix.
*
* This class may be subclassed so that alternative representations can
* be created. The class defines an API and a default implementation that
* the vtkAffineWidget interacts with to render itself in the scene.
*
* @warning
* The separation of the widget event handling and representation enables
* users and developers to create new appearances for the widget. It also
* facilitates parallel processing, where the client application handles
* events, and remote representations of the widget are slaves to the
* client (and do not handle events).
