| This is the registry of GLX opcodes, error codes, and event codes. It is |
| very rarely modified since there is almost no interest in supporting GLX |
| with modern OpenGL features, and the work of extending the XML schema to |
| express it is not worthwhile. |
| |
| When new GLX protocol is needed for extension specifications, allocate it |
| here and reflect it in the extension specification document as well as, if |
| appropriate, glx.xml. |
| |
| Reserved opcode ranges assigned to vendors, and in some cases, opcodes |
| actually assigned within that range are tracked here. Not all opcodes used |
| by vendors are known. |
