-/* This is included multiple times with different definitions for

- *
- * COGL_EXT_BEGIN:
- *
- * @name: a unique symbol name for this feature
- *
- * @min_gl_major: the major part of the minimum GL version where these
- * functions are available in core, or 255 if it isn't available in
- * any version.
- * @min_gl_minor: the minor part of the minimum GL version where these
- * functions are available in core, or 255 if it isn't available in
- * any version.
- *
- * @gles_availability: flags to specify which versions of GLES the
- * functions are available in. Should be a combination of
- * COGL_EXT_IN_GLES and COGL_EXT_IN_GLES2.
- *
- * @extension_suffixes: A zero-separated list of suffixes in a
- * string. These are appended to the extension name to get a complete
- * extension name to try. The suffix is also appended to all of the
- * function names. The suffix can optionally include a ':' to specify
- * an alternate suffix for the function names.
- *
- * @extension_names: A list of extension names to try. If any of these
- * extensions match then it will be used.
