    Fix array overruns in the new Filling solver pass.
    
    Probably because I wrote a couple of loops up to the maximum cell
    value using the non-idiomatic <= for their termination test, I also
    managed to use <= inappropriately for iterating over every cell of the
    grid, leading to a couple of references just off the end of arrays.
    
    Amusingly, it was the Emscripten front end which pointed this out to
    me by actually crashing as a result! Though valgrind found it just
    fine too, once I thought to run that. But it comes to something when
    running your C program in Javascript detects your memory errors :-)
