   6                     Requests the internal storage format of the texture image.  The most
   7                     current version of the SGI implementation of GLU does not check this
   8                     value for validity before passing it on to the underlying OpenGL
   9                     implementation.  A value that is not accepted by the OpenGL
  10                     implementation will lead to an OpenGL error.  The benefit of not
  11                     checking this value at the GLU level is that OpenGL extensions can add
  12                     new internal texture formats without requiring a revision of the GLU
  13                     implementation.  Older implementations of GLU check this value and
  14                     raise a GLU error if it is not 1, 2, 3, or 4 or one of the following
