SoTextureCoordinate2(3) on Linux
The text d5bfb25eb96c, as Debian 6.0 (Squeeze) shipped it.
The SoTextureCoordinate2 class contains a set of coordinates for the mapping of 2D textures. When encountering nodes of this type during traversal, the coordinates it contains will be put on the state stack. Some shape nodes (for instance SoIndexedFaceSet, among many others) can then use these coordinates for explicit, detailed control of how textures are mapped to it's surfaces.
