* KEYWORD1 - usually nothing, but might be __declspec(dllexport) on Win32
* KEYWORD2 - usually nothing, but might be __stdcall on Win32
* NAME(n) - builds the final function name (usually add "gl" prefix)
* DISPATCH(func, args, msg) - code to do dispatch of named function.
* msg is a printf-style debug message.
* RETURN_DISPATCH(func, args, msg) - code to do dispatch with a return value
*
* Here's an example which generates the usual OpenGL functions:
* #define KEYWORD1
* #define KEYWORD2
* #define NAME(func) gl##func
