            <code class="function">glFramebufferRenderbuffer</code> attaches a renderbuffer as one of the logical buffers of the
            currently bound framebuffer object. <em class="parameter"><code>renderbuffer</code></em> is the name of the renderbuffer object
            to attach and must be either zero, or the name of an existing renderbuffer object of type <em class="parameter"><code>renderbuffertarget</code></em>.
            If <em class="parameter"><code>renderbuffer</code></em> is not zero and if <code class="function">glFramebufferRenderbuffer</code> is
            successful, then the renderbuffer name <em class="parameter"><code>renderbuffer</code></em> will be used as the logical buffer
            identified by <em class="parameter"><code>attachment</code></em> of the framebuffer currently bound to <em class="parameter"><code>target</code></em>.
        </p><p>
            The value of <code class="constant">GL_FRAMEBUFFER_ATTACHMENT_OBJECT_TYPE</code> for the specified attachment point is
            set to <code class="constant">GL_RENDERBUFFER</code> and the value of <code class="constant">GL_FRAMEBUFFER_ATTACHMENT_OBJECT_NAME</code>
            is set to <em class="parameter"><code>renderbuffer</code></em>. All other state values of the attachment point specified by
            <em class="parameter"><code>attachment</code></em> are set to their default values. No change is made to the state of the renderbuuffer
            object and any previous attachment to the <em class="parameter"><code>attachment</code></em> logical buffer of the framebuffer
            <em class="parameter"><code>target</code></em> is broken.
        </p><p>
            Calling <code class="function">glFramebufferRenderbuffer</code> with the renderbuffer name zero will detach the image, if any,
            identified by <em class="parameter"><code>attachment</code></em>, in the framebuffer currently bound to <em class="parameter"><code>target</code></em>.
            All state values of the attachment point specified by attachment in the object bound to target are set to their default values.
        </p><p>
            Setting <em class="parameter"><code>attachment</code></em> to the value <code class="constant">GL_DEPTH_STENCIL_ATTACHMENT</code> is a special
            case causing both the depth and stencil attachments of the framebuffer object to be set to <em class="parameter"><code>renderbuffer</code></em>,
            which should have the base internal format <code class="constant">GL_DEPTH_STENCIL</code>.
