            <code class="function">glPopDebugGroup</code> 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 <em class="parameter"><code>message</code></em>
            string, the source <em class="parameter"><code>source</code></em>, and an ID <em class="parameter"><code>id</code></em>
            submitted to the corresponding <a href="glPushDebugGroup.xml"><span class="citerefentry"><span class="refentrytitle">glPushDebugGroup</span></span></a>
            command. <code class="constant">GL_DEBUG_TYPE_PUSH_GROUP</code> and <code class="constant">GL_DEBUG_TYPE_POP_GROUP</code>
            share a single namespace for message <em class="parameter"><code>id</code></em>.
            <em class="parameter"><code>severity</code></em> has the value <code class="constant">GL_DEBUG_SEVERITY_NOTIFICATION</code>. The <em class="parameter"><code>type</code></em>
            has the value <code class="constant">GL_DEBUG_TYPE_POP_GROUP</code>. Popping a debug group restores
            the debug output volume control of the parent debug group.
