            <function>glRenderbufferStorage</function> is equivalent to calling
            <citerefentry><refentrytitle>glRenderbufferStorageMultisample</refentrytitle></citerefentry> with the

        <para>
            The target of the operation, specified by <parameter>target</parameter> must be <constant>GL_RENDERBUFFER</constant>.
            <parameter>internalformat</parameter> specifies the internal format to be used for the renderbuffer object's storage and
            must be a color-renderable, depth-renderable, or stencil-renderable format.
            <parameter>width</parameter> and <parameter>height</parameter> are the dimensions, in pixels, of the renderbuffer.
            Both <parameter>width</parameter> and <parameter>height</parameter> must be less than or equal to the value of
            <constant>GL_MAX_RENDERBUFFER_SIZE</constant>.

        <para>
            Upon success, <function>glRenderbufferStorage</function> deletes any existing data store for the renderbuffer
            image and the contents of the data store after calling <function>glRenderbufferStorage</function> are undefined.

            <constant>GL_INVALID_VALUE</constant> is generated if either of <parameter>width</parameter> or <parameter>height</parameter> is negative,
