/**
* @class vtkImplicitWindowFunction
* @brief implicit function maps another implicit function to lie within a specified range
*
* vtkImplicitWindowFunction is used to modify the output of another
* implicit function to lie within a specified "window", or function
* range. This can be used to add "thickness" to cutting or clipping
* functions.
*
* This class works as follows. First, it evaluates the function value of the
* user-specified implicit function. Then, based on the window range specified,
* it maps the function value into the window values specified.
