MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

From the EXT_external_objects_fd spec:

   "If the GL_EXT_memory_object_fd string is reported, the following
    commands are added:

    void ImportMemoryFdEXT(uint memory,
                           uint64 size,
                           enum handleType,
                           int fd);"
