class_docstr: Visualize triangulation process stepwise to aid in debugging.
  
  *interval* specifies the diration to wait before drawing each update in
  the triangulation procedure. Negative values cause the display to wait
  until the user clicks on the window for each update.
  
  *skip* causes the display to immediately process the first N events
  before pausing.

      k = Triangulation._remove_tri(self, *args, **kwargs)
