// .NAME vtkPixel - a cell that represents an orthogonal quadrilateral
// .SECTION Description
// vtkPixel is a concrete implementation of vtkCell to represent a 2D
// orthogonal quadrilateral. Unlike vtkQuad, the corners are at right angles,
// and aligned along x-y-z coordinate axes leading to large increases in
// computational efficiency.
