// .NAME vtkDensifyPolyData - Densify the input by adding points at the
// centroid
//
// .SECTION Description
// The filter takes any polygonal data as input and will tessellate cells that
// are planar polygons present by fanning out triangles from its centroid.
// Other cells are simply passed through to the output. PointData, if present,
// is interpolated via linear interpolation. CellData for any tessellated cell
// is simply copied over from its parent cell. Planar polygons are assumed to
// be convex. Funny things will happen if they are not.
//
// The number of subdivisions can be controlled by the parameter
// NumberOfSubdivisions.
