SoGLPointSizeElement(3) on Linux
The text 5685c3d0d178, as Debian 7 (Wheezy) shipped it.
The SoGLPointSizeElement class changes the pointsize setting of the OpenGL render state. Requests from the scenegraph to change the pointsize when rendering point primitives will be made through this element, which forwards it to the appropriate native OpenGL call.
