Store texture as map?

The "TODO" in glview.cc seems difficult/impossible unless the textures are stored as an associated container... should the definition of Model be given maps instead of vectors for some cases? tinygltf/examples/glview/glview.cc:424

In a glTF asset, everything is actually stored as arrays.

Material refer to texture as their index in the "texture" array. This kind of storage makes sense for tinygltf. Same goes for a texture source, it's an image.

Exactly the same for accessing all the binary data. Node -> Mesh -> accessor(s) -> bufferView -> buffer.

Each of these "->" is just an index in the corresponding array.

Hope this helps!

@pkarasev3-tri which "TODO" are you referring to exactly?
