vtkTriangle 'dead code' not dead when give NaNs
vtkTriangle returns an assertion about dead code when it is given NaN inputs. This was identified when NaNs were input to the 'FindClosestpoint' function in a cell locator object. The assertion is found in line 306 of vtkTriangles.cxx
I've been asked to create an issue to ensure that a test can be added for this case too.
