This test cycles through a model exported in different formats and with different materials with tangents
generated in different ways. The normal map should look correct in all cases. Refer to
https://github.com/KhronosGroup/glTF-Sample-Models/tree/master/2.0/NormalTangentMirrorTest for details on
the correct result and debugging.
