/**
* @class vtkResliceCursorLineRepresentation
* @brief represent the vtkResliceCursorWidget
*
* This class provides a representation for the reslice cursor widget. 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.
