Just a note on terminology. A true "area flooding" algorithm has nothing to
do with whether the shape being filled is polygonal or not. In fact, since
it is based solely on pixel values in the frame buffer, the outline can be
any weird curved shape you want. This is in contrast to a true "polygon fill"
algorithm which has nothing to do with the contents of the frame buffer,
being derived solely from an input list of vertices. The latter is also a
couple of orders of magnitude more difficult to write properly, and requires
some heavy hardware to approach real-time. Micros all use the former.
