// VZ: we use a separate function to do the actual colour mapping because
// otherwise VC++ optimizer seems to mangle the code in MapBitmap(): with
// optimization on, the code produces incorrect result (but it's ok in
// debug mode, i.e. globally without optimizations or if you insert a
// #pragma optimize("", off) just before the function!)

// This will also make it simpler to replace MapColours() later with
// something more efficient...
