            The implementation may use this information to store information
            that may be useful for a future query of the program's binary.
            It is recommended to set
            <constant>GL_PROGRAM_BINARY_RETRIEVABLE_HINT</constant> for the
            program to <constant>GL_TRUE</constant> before calling
            <citerefentry><refentrytitle>glLinkProgram</refentrytitle></citerefentry>,

            retrieved later.
