- Unfortunately aiNode has bone structures and meshes too, yet we can't assign
- the mesh to a bone aiNode as a skin may refer to several aiNodes. Therefore
- I've decided to import into this structure:
-
-   aiScene->mRootNode
-    |        |->mMeshes (all the meshes)
-    |        \->children (empty if there's no skeleton imported, no meshes)
-    |             \->skeleton root aiNode*
-    |                   |->bone aiNode
-    |                   |   \->subbone aiNode
-    |                   |->bone aiNode
-    |                   |   ...
-    |                   \->bone aiNode
-    \->mMeshes[]
-        \->aiBone, referencing mesh-less aiNodes from above
-
-  * - normally one, but if a model has several skeleton roots, then all of them
-      are listed in aiScene->mRootNode->children, but all without meshes
