The models were too optimized. Since each face converging at one vertex
could have different texture coordinates, we need to make vertices
of each face unique, so that we can have unique texture coordinates
for each of them. Naturally this increases the rendered vertex count
significantly, but at least the textures are now mapped correctly.
