[vtk-developers] Quadratic convenience classes in vtkUnstructuredGrid

[Moreland, Kenneth]

I was doing some debugging and noticed that several of the convenience
vtkCell classes for some of the quadratic types (QuadraticLinearQuad,
BiQuadraticQuad, etc.) are being instantiated in the vtkUnstructuredGrid
constructor whereas all the others are set to NULL until used.  Is there
a reason for this?
