Yes, I used toLua because we had to start and finish the project in just two  
weeks. Was quite heavy but I got it. I wrote the loader/maintenance module at  
the last day. Most of the development was done using C++ on Windows. Just  
copied it into an empty project for the target platform, compiled it and it  
worked as expected. :)

What we did was the following (C++ syntax):

for (unsigned ui=0; ui!=512; ++ui) {
        LineChecker[ui].setStart(TCameraPoint(ui, 0));
        LineChecker[ui].setEnd(TCameraPoint(ui, 479));
        LineChecker[ui].run(Image);
}

The Lua code was 5x slower. Too slow for us.
