27 Use Skeleton if you wish to manually create the joints of a skeleton for
28 use with skinned meshes. This is mainly of use to people creating editors,
29 tooling, or dynamic skeletons. It is more common that a Qt 3D application
30 would simply consume an existing skeleton and skinned mesh as created in
31 a digital content creation tool such as Blender. For this use case, please
