little error in retrieving the normals from the geometry

[radcheb]

In the file "csg.js/csg.js" line48:
vertex = new ThreeBSP.Vertex( vertex.x, vertex.y, vertex.z, face.vertexNormals[2], uvs );

I think we should get the normal from the array vertexNormals with key 1 instead of key 2:

vertex = new ThreeBSP.Vertex( vertex.x, vertex.y, vertex.z, face.vertexNormals[1], uvs );

Thanks, Radhwane C.

Why's that?

[radcheb]

Because you should use all the normal while you're using twice the vertexNormals[2].
