/**
* @class vtkCursor3D
* @brief generate a 3D cursor representation
*
* vtkCursor3D is an object that generates a 3D representation of a cursor.
* The cursor consists of a wireframe bounding box, three intersecting
* axes lines that meet at the cursor focus, and "shadows" or projections
* of the axes against the sides of the bounding box. Each of these
* components can be turned on/off.
*
* This filter generates two output datasets. The first (Output) is just the
* geometric representation of the cursor. The second (Focus) is a single
* point at the focal point.
