            <function>glRenderbufferStorageMultisample</function> establishes the data storage, format, dimensions and number of
            samples of a renderbuffer object's image.
        </para>
        <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>. <parameter>samples</parameter> specifies the number of samples to be used
            for the renderbuffer object's image, and must be less than or equal to the value of <constant>GL_MAX_SAMPLES</constant>.
            If <parameter>internalformat</parameter> is a signed or unsigned integer format then <parameter>samples</parameter> must be
            less than or equal to the value of <constant>GL_MAX_INTEGER_SAMPLES</constant>.
        </para>
        <para>
            Upon success, <function>glRenderbufferStorageMultisample</function> deletes any existing data store for the renderbuffer
            image and the contents of the data store after calling <function>glRenderbufferStorageMultisample</function> are undefined.

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

        <para>
            <constant>GL_OUT_OF_MEMORY</constant> is generated if the GL is unable to create a data store of the requested size.
