draws a interactive polyline
This is a vtkContextItem that can be placed into a vtkContextScene. It draws a polyline, and reacts to mouse events. Initially there are 2 points at the ends of the line. Provides the ability to add, remove, and move anchor points. This is not a universal polyline and is designed to adjust the reference points for the digital signal processing algorithm. So there are a number of features for interacting with the line:
