FIXED : Volume rendered from 2D images is now a vtkprop of the image component. The arbirtrary slice holds the volume rendered prop and is displayed with the arbitrary slice, if computed. As a consequence, the volume rendered prop is deleted once the component is closed. Also the prop is only computed once. It should correctly work for the Labex ECCAMI.
TODO: Use a InterfaceRepresentation interface to correctly delegate the get/remove... prop methods in Component.h using the delegation pattern. Also, the volume rendered 3D image could be a kind of "Single Component" and being displayed as axial/coronal ... slice (right clicking a check-box in a pop-up menu). To be decided next.
