/**
 * @class   vtkResliceCursorWidget
 * @brief   represent a reslice cursor
 *
 * This class represents a reslice cursor that can be used to
 * perform interactive thick slab MPR's through data. It
 * consists of two cross sectional hairs, with an optional thickness. The
 * hairs may have a hole in the center. These may be translated or rotated
 * independent of each other in the view. The result is used to reslice
 * the data along these cross sections. This allows the user to perform
 * multi-planar thin or thick reformat of the data on an image view, rather
 * than a 3D view. The class internally uses vtkImageSlabReslice
 * or vtkImageReslice depending on the modes in vtkResliceCursor to
 * do its reslicing. The slab thickness is set interactively from
 * the widget. The slab resolution (ie the number of blend points) is
 * set as the minimum spacing along any dimension from the dataset.
