[vtkusers] MIP Projection on a 3D Plane

[Jose Ignacio Prieto]

Hi Jon, I wan to modify Medical1 example, so I still have the skin
contour in the center of the screen and have an MIP projection of the
volume in a 2D plane to the right of the contour, so you can see both
things at the same time. I want the projection to update itself if I
change the zoom,  view angle or contrast. It would be similar as the
software 3dSlicer, where you have a volume in one window and the
projection in another. I don't know if this is one mapper and two
actors, of they just share the data source and the mouse interaction
is deliberately done in both windows. Thanks
