[vtkusers] How to draw lines in wxWindow

[Julian Ibarz]

Hum the position are defined in space coordinate so you need to explicitely
make them in world coordinate. When you create the vtkLineWidget and give it
his position, take the renderer where the vtkLineWidget will be added and do
that :

vtkRenderer renderer;
renderer.SetDisplayPoint(x,y,0);

Where x y are the position of the mouse in vtk display coordinate and 0
means you will put the line on the near plane (1 for the far plane...).

and follow by I thing like that :

renderer.DisplayToWorld();
double[] worldPoints = renderer.GetWorldPoint();
lineWidget->SetPoint1(worldPoints);
etc.
