/**
 * @class   vtkOutlineSource
 * @brief   create wireframe outline around bounding box
 *
 * vtkOutlineSource creates a wireframe outline around a
 * user-specified bounding box.  The outline may be created aligned
 * with the {x,y,z} axis - in which case it is defined by the 6 bounds
 * {xmin,xmax,ymin,ymax,zmin,zmax} via SetBounds(). Alternatively, the
 * box may be arbitrarily aligned, in which case it should be set via
 * the SetCorners() member.
