ray-cast cell picker for all kinds of Prop3Ds
vtkCellPicker will shoot a ray into a 3D scene and return information about the first object that the ray hits. It works for all Prop3Ds. For vtkVolume objects, it shoots a ray into the volume and returns the point where the ray intersects an isosurface of a chosen opacity. For vtkImage objects, it intersects the ray with the displayed slice. For vtkActor objects, it intersects the actor's polygons. If the object's mapper has ClippingPlanes, then it takes the clipping into account, and will return the Id of the clipping plane that was intersected. For all prop types, it returns point and cell information, plus the normal of the surface that was intersected at the pick position. For volumes and images, it also returns (i,j,k) coordinates for the point and the cell that were picked.
