Zero Division Error calling computeDelaunayTriangulation function #1

Description

@csotomon

Running the computeDelaunayTriangulation function with a 7.2 millions of point i am getting this error:

checking the code if "think" that the error is in the line 458 because s1.y and s2.y have the same value.
