[vtkusers] Drawing a simple line graph (CONTINUES...)

Dean, vtkXYPlotActor works OK, but I think it isn't the best way to draw a
line or a polygon in the plane. The methods for adjusting vtkActor2D's
dimensions should work properly. In fact, vtkXYPlotActor inherits theese
methods from vtkActor2D. However, there might be another way to do this. I'm
a begginer, and I thought drawing a simple line would be simple to; I
wouldn't like to think that such a complex system like VTK has this type of
holes. There must be something that has to be changed in pipelines like the
one in my code, something additional... The fact that vtkActor2D doesn't use
a 4x4 matrix says somthing to me, and also the render process must have to
do something with this. I would like to know how the renderer is working...
But again, It's strange that ->GetPosition2Coordinate()->SetValue(x,y) works
for vtkXYPlotActor and not for its mother class vtkActor2D (where the method
is initially defined)...
