SoTextureScalePolicy(3) on Linux
The text 82e92f6bf647, as Debian 8 (Jessie) shipped it.
The SoTextureScalePolicy class is a node for controlling the texture scale policy. If a texture map is of size != 2^n, it must be scaled before OpenGL can handle it. This node enables you to control how/if textures are scaled before it is sent to OpenGL.
