[vtkusers] Add a Rectangle Actor to VTK RenderWindow

[Alex Southern]

On this subject,

if I change the positions of the points after the actor has been 
rendered. How would I go about updating the render window to show the 
new positions?

Do I have to delete all the used smartpointers and repeat the code 
again? No doubt this will work but is there a better way?

Thanks
Alex
