SoTexture3Transform(3) on Linux
The text 5d698ddf4fe4, as Debian 7 (Wheezy) shipped it.
The SoTexture3Transform class is used to define 3D texture transformations. Textures applied to shapes in the scene can be transformed by 'prefixing' in the state with instances of this node type. Translations, rotations and scaling in 3D can all be done.
