Using width and height on an svg element defeats the purpose of using svg. It is better to use the viewbox. I applied the scale to the viewbox instead of the polygons to simplify future animations. (This article explains it nicely: https://css-tricks.com/scale-svg/ )

Also, I added a conditional to only apply fill-opacity to individual elements if they are different from the 1st shape's alpha channel (maybe there's a better way to do this than array[0]).

Heads up, this panics for me: with -s 128 on a 256px working image the scale is 0.5, so int(scale) is 0 and NewModel divides by zero. With a non-integer scale (e.g. -s 400) the viewBox comes out as 400x400 even though the shapes are in the 256px input space, so the drawing only covers part of the image. Using the input image's width/height for the viewBox fixes both. I did that in my fork if it helps: https://github.com/loyality7/primitive
