[vtkusers] How to initialize vtkAngleWidget with three points specified?

[Karthik Krishnan]

Here is a minimal example demonstrating the use of vtkAngleWidget and
its 2D rep and initializing it with either user specified display
positions -or- user specified world positions for the two end points
and the center. Please find it attached.

You can run it by supplying the display positions of its end points

     AngleWidget2D --InitializeDisplayPositions 240 240 240 10 230 2 220 11 230

or by supplying the world positions for the end points:

     AngleWidget2D --InitializeDisplayPositions 240 240 240 10 230 2 220 11 230

Does this answer your question ? We'll try to add this as a test to
the test suite one of these days :)
