28/* The files in this folder are included multiple times with different
29 * definitions for these macros. The macros are given the following arguments:
30 *
31 * GST_GL_EXT_BEGIN:
32 *
33 * @name: a unique symbol name for this feature
34 *
35 * @min_gl_major: the major part of the minimum GL version where these
36 * functions are available in core, or 255 if it isn't available in
37 * any version.
38 * @min_gl_minor: the minor part of the minimum GL version where these
39 * functions are available in core, or 255 if it isn't available in
40 * any version.
41 *
42 * @gles_availability: flags to specify which versions of GLES the
43 * functions are available in. Should be a combination of
44 * GST_GL_API_GLES and GST_GL_API_GLES2.
45 *
46 * @extension_suffixes: A zero-separated list of suffixes in a
47 * string. These are appended to the extension name to get a complete
48 * extension name to try. The suffix is also appended to all of the
49 * function names. The suffix can optionally include a ':' to specify
50 * an alternate suffix for the function names.
51 *
52 * @extension_names: A list of extension names to try. If any of these
53 * extensions match then it will be used.
