// .NAME vtkMaskPoints - selectively filter points
// .SECTION Description
// vtkMaskPoints is a filter that passes through points and point attributes
// from input dataset. (Other geometry is not passed through.) It is
// possible to mask every nth point, and to specify an initial offset
// to begin masking from. A special random mode feature enables random
// selection of points. The filter can also generate vertices (topological
// primitives) as well as points. This is useful because vertices are
// rendered while points are not.
