// .NAME vtkPolygonBuilder -builds a polygon from a set of abstract triangles (represented by index triplets)
//
// .SECTION Description
// The polygon output is the boundary of the union of the triangles.
// It is assumed that the input triangles form a simple polygon. It is
// currently used to compute polygons for slicing.
