/**
* @class vtkAffineWidget
* @brief perform affine transformations
*
* The vtkAffineWidget is used to perform affine transformations on objects.
* (Affine transformations are transformations that keep parallel lines parallel.
* Affine transformations include translation, scaling, rotation, and shearing.)
*
* To use this widget, set the widget representation. The representation
* maintains a transformation matrix and other instance variables consistent
* with the transformations applied by this widget.
*
* @par Event Bindings:
* By default, the widget responds to the following VTK events (i.e., it
* watches the vtkRenderWindowInteractor for these events):
* <pre>
* LeftButtonPressEvent - select widget: depending on which part is selected
* translation, rotation, scaling, or shearing may follow.
* LeftButtonReleaseEvent - end selection of widget.
* MouseMoveEvent - interactive movement across widget
* </pre>
*
* @par Event Bindings:
* Note that the event bindings described above can be changed using this
* class's vtkWidgetEventTranslator. This class translates VTK events
* into the vtkAffineWidget's widget events:
* <pre>
* vtkWidgetEvent::Select -- focal point is being selected
* vtkWidgetEvent::EndSelect -- the selection process has completed
* vtkWidgetEvent::Move -- a request for widget motion
* </pre>
*
* @par Event Bindings:
* In turn, when these widget events are processed, the vtkAffineWidget
* invokes the following VTK events on itself (which observers can listen for):
* <pre>
* vtkCommand::StartInteractionEvent (on vtkWidgetEvent::Select)
* vtkCommand::EndInteractionEvent (on vtkWidgetEvent::EndSelect)
* vtkCommand::InteractionEvent (on vtkWidgetEvent::Move)
* </pre>
*
