// .NAME vtkVolumeRayCastCompositeFunction - a ray function for compositing
// .SECTION Description
// vtkVolumeRayCastCompositeFunction is a ray function that can be used
// within a vtkVolumeRayCastMapper. This function performs compositing along
// the ray according to the properties stored in the vtkVolumeProperty for
// the volume.
