Generate normals based on FBX face_smoothing data: - Smooth faces share averaged normals across vertices - Faceted faces maintain hard edges - Preserves artist-defined smoothing behavior

Feature request: Kosyne found it convenient to be able to choose between calculating, importing or outright discarding smoothing group data. |

Discussed with @bqqbarbhg We think that ufbx is probably doing the "correct" thing here, but many things export hard edges unexpectedly. So it's a good idea to default to what the fbx file says, or discarding smooth data or discarding hard edges or we can try recalculating (this pull request). |
