            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, as shown in Table 1 below.
            <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>. <parameter>samples</parameter> specifies the number of samples to be used
            for the renderbuffer object's image. If <parameter>internalformat</parameter> is a signed or unsigned integer format then
                        <parameter>samples</parameter> must be 0.  Otherwise, <parameter>samples</parameter> must be must be less than or equal to
                        the maximum number of samples supported for <parameter>internalformat</parameter>.

        <para>
            Since different implementations may support different sample counts for multisample
                        rendering, the actual number of samples allocated for the renderbuffer image is
                        implementation-dependent. However, the resulting value for <constant>GL_RENDERBUFFER_SAMPLES</constant>
                        is guaranteed to be greater than or equal to <parameter>samples</parameter> and no more than the
                        next larger sample count supported by the implementation.
