-// 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...
