            <function>glXCreatePixmap</function> creates an off-screen rendering area and returns its XID.
            Any GLX rendering context that was created with respect to <parameter>config</parameter>
            can be used to render into this window.
            Use <citerefentry><refentrytitle>glXMakeCurrent</refentrytitle></citerefentry> to associate the rendering area with a GLX
            rendering context.

            If the GLX version is 1.1 or 1.0, the GL version must be 1.0.
            If the GLX version is 1.2, then the GL version must be 1.1.
            If the GLX version is 1.3, then the GL version must be 1.2.
