weirdly, i've seen this "blit the first pixel elsewhere" trick mentioned a lot but i got polygon filling to work fine without knowing about it... it is simple enough just to use a "Height" value in BLTSIZE one less than you would usually, to omit plotting the final pixel. (without changing any of the other blitter registers, therefore not affecting the slope of the line)
