/* 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.
