With iters=1500, lines=20, p0_y = p1_y = p2_y = 200, p0_m = p1_m = p2_m = 10,
p0_x = 300, p1_x = 400, p2_x = 500, p3_m = p4_m = p5_m = 0, the plot looks
symmetric across y=200 and across x=400, as one would expect. However, with
p1_m changed from +10 to -10 the picture loses symmetry across x=400.
Is that a bug?

While that feature works, leaving mass parameters blank doesn't work to
turn off a point. Probably should fix it so blank mass acts like 0 too.
