William Deurwaarder 9e58b02252 GPULightmapper: skip smoothen positions for flat triangles ...

Smoothening positions for flat, non-smoothened, triangles is unnecessary and
caused positions to move outside their  triangle which caused side-effects as
rays from those positions intersected with triangles which could not be
reached from the original triangle.

This is solved by skipping smoothening of positions for flat triangles.
A triangle is determined to be flas as its vertex normals are equal.
