performs piecewise linear ray integration.
vtkUnstructuredGridPartialPreIntegration performs piecewise linear ray integration. This will give the same results as vtkUnstructuredGridLinearRayIntegration (with potentially a error due to table lookup quantization), but should be notably faster. The algorithm used is given by Moreland and Angel, "A Fast High Accuracy Volume Renderer for Unstructured Data."
This class is thread safe only after the first instance is created.

Given a set of intersections (defined by the three arrays), compute the piecewise integration of the array in front to back order.
/c intersectionLengths holds the lengths of each piecewise segment. /c nearIntersections and /c farIntersections hold the scalar values at the front and back of each segment. /c color should contain the RGBA value of the volume in front of the segments passed in, and the result will be placed back into /c color.
