// .NAME vtkUnstructuredGridLinearRayIntegrator - performs piecewise linear ray integration.
//
// .SECTION Description
//
// vtkUnstructuredGridLinearRayIntegrator performs piecewise linear ray
// integration. Considering that transfer functions in VTK are piecewise
// linear, this class should give the "correct" integration under most
// circumstances. However, the computations performed are fairly hefty and
// should, for the most part, only be used as a benchmark for other, faster
// methods.
