/**
* @class vtkQuad
* @brief a cell that represents a 2D quadrilateral
*
* 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.
