TexImage3d marked as deprecated
Last modified: 2013-04-03 08:56:51 PDT
gl.spec marks TexImage3d as deprecated in OpenGL 3.1 . However, this method is still available in OpenGL 4.1 core profile, as evidenced by the reference card. 
This affects the C# bindings found at http://www.opentk.com, which respect deprecation warnings.
I've just run into this too with the Qt OpenGL code generator. I'll special case it there but it would be nice if this simple mistake could be fixed in gl.spec.
