The \PNG\ and \SVG\ backends are not available in \LUATEX, because it's complex
to manage the math formulas at run time. In this respect \POSTSCRIPT\ and the
highlevel |objects| are better, and they are the standard way. Another problem is
how to emit the warning: the |normal_warning| function is not available when
\LUATEX\ is called as \LUA\ only.
