SoTexture2Transform(3) on Linux
The text 32ec1ac03d99, as Debian 7 (Wheezy) shipped it.
The SoTexture2Transform class is used to define 2D 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 2D can all be done.
