// .NAME vtkQuad - a cell that represents a 2D quadrilateral
// .SECTION Description
// vtkQuad is a concrete implementation of vtkCell to represent a 2D
// quadrilateral. vtkQuad is defined by the four points (0,1,2,3) in
// counterclockwise order. vtkQuad uses the standard isoparametric
// interpolation functions for a linear quadrilateral.
