[vtkusers] Class to draw line or circle on the images

[Shekhar]

Hi Maty,

Not sure exactly what u mean but if your spheres are the same, u can 
create a single sphere source with a single mapper, then assign the 
mapper to many actors. Use vtkTransform to move them around. Is that 
what u meant?

Cheers
Shakes
