Adjustment factor for degenerate triangles. Use of this parameter depends on the value of CorrectVoronoi defined above:
if CorrectVoronoi=1, : Voronoi points are moved by this amount towards the triangle centroids.
if CorrectVoronoi=-1 : Move Voronoi points to centroids for triangles with angles greater than or equal to VoronoiRatio.
if CorrectVoronoi=0:no correction is performed.
