51 | Requests the internal storage format of the texture image. The most | |
52 | current version of the SGI implementation of GLU does not check this | |
53 | value for validity before passing it on to the underlying OpenGL | |
54 | implementation. A value that is not accepted by the OpenGL | |
55 | implementation will lead to an OpenGL error. The benefit of not | |
56 | checking this value at the GLU level is that OpenGL extensions can add | |
57 | new internal texture formats without requiring a revision of the GLU | |
58 | implementation. Older implementations of GLU check this value and | |
59 | raise a GLU error if it is not 1, 2, 3, or 4 or one of the following | |
