// .NAME vtkTriangleFilter - convert input polygons and strips to triangles
// .SECTION Description
// vtkTriangleFilter generates triangles from input polygons and triangle
// strips.  It also generates line segments from polylines unless PassLines
// is off, and generates individual vertex cells from vtkVertex point lists
// unless PassVerts is off.
