            <function>glPopDebugGroup</function> pops the active debug group.
            After popping a debug group, the GL will also generate a debug
            output message describing its cause based on the <parameter>message</parameter>
            string, the source <parameter>source</parameter>, and an ID <parameter>id</parameter>
            submitted to the corresponding <citerefentry><refentrytitle>glPushDebugGroup</refentrytitle></citerefentry>
            command. <constant>GL_DEBUG_TYPE_PUSH_GROUP</constant> and <constant>GL_DEBUG_TYPE_POP_GROUP</constant>
            share a single namespace for message <parameter>id</parameter>.
            <parameter>severity</parameter> has the value <constant>GL_DEBUG_SEVERITY_NOTIFICATION</constant>. The <parameter>type</parameter>
            has the value <constant>GL_DEBUG_TYPE_POP_GROUP</constant>. Popping a debug group restores
            the debug output volume control of the parent debug group.
