[vtkusers] save mhd from QVTKWidget

[Dženan Zukić]

You cannot save 3D image from QVTKWidget, because QVTKWidget is a 2D widget.
To save 3D image you have to access vtkVolume which you added to the scene
earlier. If however you have a polygonal scene which you want to voxelize,
take a look here: http://www.vtk.org/Wiki/VTK/Examples/Broken/VoxelModeller
