#include <vtkSMPickLineWidgetProxy.h>
This class is based on vtkPickLineWidget. Instead of creating a client instance on vtkPickLineWidget, the functionality of picking has been moved to the proxy, since, picking needs RenderModuleProxy, and hence typically, never reside on the Servers. This is a subclass of vtkSMLineWidgetProxy that has key bindings for picking the ends of the line widget. I plan to have the first 'p' pick the end closest to the picked point, subsequent 'p' will toggle between the two ends. We could make a new widget that would continue to add line segments.
