// .NAME vtkRectilinearWipeWidget - interactively control an instance of vtkImageRectilinearWipe filter
// .SECTION Description
// The vtkRectilinearWipeWidget is used to interactively control an instance
// of vtkImageRectilinearWipe (and an associated vtkImageActor used to
// display the rectilinear wipe). A rectilinear wipe is a 2x2 checkerboard
// pattern created by combining two separate images, where various
// combinations of the checker squares are possible. Using this widget, the
// user can adjust the layout of the checker pattern, such as moving the
// center point, moving the horizontal separator, or moving the vertical
// separator. These capabilities are particularly useful for comparing two
// images.
//
// To use this widget, specify its representation (by default the
// representation is an instance of vtkRectilinearWipeProp). The
// representation generally requires that you specify an instance of
// vtkImageRectilinearWipe and an instance of vtkImageActor. Other instance
// variables may also be required to be set -- see the documentation for
// vtkRectilinearWipeProp (or appropriate subclass).
//
// By default, the widget responds to the following events:
// <pre>
// Selecting the center point, horizontal separator, and verticel separator:
// LeftButtonPressEvent - move the separators
// LeftButtonReleaseEvent - release the separators
// MouseMoveEvent - move the separators
// </pre>
// Selecting the center point allows you to move the horizontal and vertical
// separators simultaneously. Otherwise only horizontal or vertical motion
// is possible/
//
// Note that the event bindings described above can be changed using this
// class's vtkWidgetEventTranslator. This class translates VTK events into
// the vtkRectilinearWipeWidget's widget events:
// <pre>
// vtkWidgetEvent::Select -- some part of the widget has been selected
// vtkWidgetEvent::EndSelect -- the selection process has completed
// vtkWidgetEvent::Move -- a request for motion has been invoked
// </pre>
//
// In turn, when these widget events are processed, the
// vtkRectilinearWipeWidget invokes the following VTK events (which
// observers can listen for):
// <pre>
// vtkCommand::StartInteractionEvent (on vtkWidgetEvent::Select)
// vtkCommand::EndInteractionEvent (on vtkWidgetEvent::EndSelect)
// vtkCommand::InteractionEvent (on vtkWidgetEvent::Move)
// </pre>
//
// .SECTION Caveats
// The appearance of this widget is defined by its representation, including
// any properties associated with the representation. The widget
// representation is a type of vtkProp that defines a particular API that
// works with this widget. If desired, the vtkProp may be subclassed to
// create new looks for the widget.
