functionally the same, but while in h264 they take the surrounding
pixels directly out of the framebuffer I get them out of arrays top and
left. This is due to the fact that the rules how to set pixels according
to which neighbours are available are a bit more complex

I was hoping to provoke an answer like that :)

try to get back to that.
