        <para>
            <function>glCallList</function> causes the named display list to be executed.
            The commands saved in the display list are executed in order,
            just as if they were called without using a display list.
            If <parameter>list</parameter> has not been defined as a display list,
            <function>glCallList</function> is ignored.
        </para>
        <para>
            <function>glCallList</function> can appear inside a display list.
            To avoid the possibility of infinite recursion resulting from display lists
            calling one another,
            a limit is placed on the nesting level of display
            lists during display-list execution.
            This limit is at least 64, and it depends on the implementation.
        </para>
        <para>
            GL state is not saved and restored across a call to <function>glCallList</function>.
            Thus,
            changes made to GL state during the execution of a display list
            remain after execution of the display list is completed.
            Use <citerefentry><refentrytitle>glPushAttrib</refentrytitle></citerefentry>,
            <citerefentry><refentrytitle>glPopAttrib</refentrytitle></citerefentry>,
            <citerefentry><refentrytitle>glPushMatrix</refentrytitle></citerefentry>,
            and <citerefentry><refentrytitle>glPopMatrix</refentrytitle></citerefentry> to preserve GL state across <function>glCallList</function> calls.

            and the corresponding call to <citerefentry><refentrytitle>glEnd</refentrytitle></citerefentry>,
            as long as the display list includes only commands that are allowed
            in this interval.
