Bug? Vector2.PointInTriangle false on edge cases

Hi all,

Apparently points are not considered to be in a triangle when they are on the edges - is that "expected behavior"? It isn't to me...

BABYLON.Vector2.PointInTriangle(new BABYLON.Vector2(0, 0), new BABYLON.Vector2(0, 0), new BABYLON.Vector2(0, 1), new BABYLON.Vector2(1, 1))

Thanks
