@ 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. 



@c
#include <stdio.h>

extern void normal_warning(const char *t, const char *p);
extern int lua_only;
#define mplibstuff_message(BACKEND)  do {                          \
 if (lua_only) {                                                   \
   fprintf(stdout,"mplib: " #BACKEND " backend not available.\n"); \
 } else {                                                          \
   normal_warning("mplib",  #BACKEND " backend not available.");   \
 }                                                                 \
