  a cell that represents an orthogonal quadrilateral
  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.

  Inflates this pixel by a distance of dist by moving the edges of the pixel by that distance.
  Since a pixel lies in 3D, the degenerate case where the pixel is homogeneous to a line are discarted because of normal direction ambiguity. Hence, if you shrink a 2D pixel so it loses thickness in one dimension. inflating it back to its previous form is impossible.
  A degenerate pixel of dimension 1 is inflated the same way a segment would be inflated. A degenerate pixel of dimension 0 is untouched.

  In other words, (px,py,pz, px,py,pz, etc..) The coordinates are ordered consistent with the definition of the point ordering for the cell. This method returns a non-nullptr pointer when the cell is a primary type (i.e., IsPrimaryCell() is true). Note that 3D parametric coordinates are returned no matter what the topological dimension of the cell.

  vtkPixel's normal cannot be computed using vtkPolygon::ComputeNormal because its points are not sorted such that circulating on them forms the pixel.
  This is a convenient method so one can compute normals on a pixel.
