      depth sort update · eaf68626
      loring authored
      this patch modernizes VTK's depth sorting code. The following improvements
      were made:
      
      * transfrom GetCell to GetCellPoints. Building the cells one by one
        is expensive and we only need points to determine the depth. We
        can also then access the points in place.
      
      * transform qsort to std::sort. Comparisons in std::sort get inlined
        so std::sort is much faster. I also reduced the overhead of swaps
        by using a functor so that only cell id is swapped.
      
      * use templates to deal with point types instead of going through
        virtual GetValue API that converts them to double.
      
      * restructure depth computations so that they can be vectorized by
        the compiler.
      
      * I added a Cxx test to improve test coverage of the various sorting
        modes supported by this class.
      
      In tests the improved class is 2 x faster when sorting by first point
      and cell bounds, and 1.5 x faster when sorting by parametric center.
      The tests made use of a 900M cell iso-surface computed from a cosmology
      simulation, and gcc 4.9.2 with -DNDEBUG -Ofast -march=native -mavx
