The "pointy vertex" test was only considering the distance from the next (outgoing) edge to the previous point. It must also consider the distance from the previous (incoming) edge to the next point. If either are less than a quarter pixel, the vertex is considered pointy and should be removed. (884166) Also (887103), when an interior region was completely removed due to boundary simplification, it would leave a degenerate edge consisting of the same vertex. So avoid introducing a join edge when prev == next.
