+ * @min_gl_major: the major part of the minimum GL version where these

+ * @min_gl_minor: the minor part of the minimum GL version where these

+ *
+ * @gles_availability: flags to specify which versions of GLES the
+ * functions are available in. Should be a combination of
+ * GST_GL_API_GLES and GST_GL_API_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.
