// .NAME vtkSurfaceVectors - Constrains vectors to surface.
// .SECTION Description
// This filter works on point vectors. It does not work on cell vectors yet.
// A normal is conputed for a point by averaging normals of surrounding
// 2D cells. The vector is then constrained to be perpendicular to the normal.
