Uhmm I beg to differ. You are almost correct in your point about joining the vertices of a polygon and then using area flood to do polygon fill, however this incorrectly presumes the existence of a unique pixel value you draw the lines with to make up your border. To me you cannot make such an assumption if you really don't know the values in the frame buffer, hence I would not call area flooding "more general" than true polygon fill, or vice versa. They are quite different approaches. If you wish a reference, try p.456, Fundamentals of Interactive Computer Graphics, Foley and Van Dam, Addison-Wesley. Let's take this out of net.micro anyway.
