// .NAME vtkQuadraticQuad - cell represents a parabolic, 8-node isoparametric quad
// .SECTION Description
// vtkQuadraticQuad is a concrete implementation of vtkNonLinearCell to
// represent a two-dimensional, 8-node isoparametric parabolic quadrilateral
// element. The interpolation is the standard finite element, quadratic
// isoparametric shape function. The cell includes a mid-edge node for each
// of the four edges of the cell. The ordering of the eight points defining
// the cell are point ids (0-3,4-7) where ids 0-3 define the four corner
// vertices of the quad; ids 4-7 define the midedge nodes (0,1), (1,2),
// (2,3), (3,0).
// .SECTION See Also
// vtkQuadraticEdge vtkQuadraticTriangle vtkQuadraticTetra
