It looks like the low-precision problem is avoided with SVG, due to (≈l.2088)

    gen_draw(&pl, w, x, y, SVG_SCALE, SVG_SCALE);

(Only 1/SVG_SCALE = 2⁻¹⁰ is later rounded by "%.2f"; I see no reason
for such a strange code…)

The ability to see the fine structure may be much harder to implement
in SVG: one may need to
  • call gen_draw() several times;
  • implement some action-on-the-distance, so that the later calls
    only redraw the lines() commands, with different colors, and with
    decreasing widths…

I know nothing about this…  (I use inkscape, but only occasionally…)
