[raster] Improve the second pass (#58373). Besides dropout control the second horizontal sweep is supposed to clean up straight horizontal edges that are mishandled by the first vertical sweep when a line passes through pixel centers. This line would present as perfectly aligned span edges in the second sweep. * src/raster/ftraster.c (Horizontal_Sweep_Span): Replace the old implementation with a better one focusing on aligned span edges only.
