Essentially this comes down to locating the pixel in the array of bytes
pointed to by surface->pixels, and copying the relevant bytes to your
pixel variable... I could regergitate cope that has been written before,
but here is a link that I hope you will find more usefull:
The code assumes that the surface is already locked, but other than that
it should make sense.
