// .NAME vtkBiDimensionalRepresentation2D - represent the vtkBiDimensionalWidget
// .SECTION Description
// The vtkBiDimensionalRepresentation2D is used to represent the
// bi-dimensional measure in a 2D (overlay) context. This representation
// consists of two perpendicular lines defined by four
// vtkHandleRepresentations. The four handles can be independently
// manipulated consistent with the orthogonal constraint on the lines. (Note:
// the four points are referred to as Point1, Point2, Point3 and
// Point4. Point1 and Point2 define the first line; and Point3 and Point4
// define the second orthogonal line.)
//
// To create this widget, you click to place the first two points. The third
// point is mirrored with the fourth point; when you place the third point
// (which is orthogonal to the lined defined by the first two points), the
// fourth point is dropped as well. After definition, the four points can be
// moved (in constrained fashion, preserving orthogonality). Further, the
// entire widget can be translated by grabbing the center point of the widget;
// each line can be moved along the other line; and the entire widget can be
// rotated around its center point.
