Thanks everyone.
Right now I'm working on these as SVGs as althor1138 described, so they will scale to any size without any quality loss or artifacting. As SVGs, I do have to edit/recreate the Bezier curves as well. Here's a an animated gif of the layers:
Puggo, I played around with font creation last night, and it's definitely possible to recreate the font using this as source. But right now I'm just trying to get this set down accurately as an SVG.
Thanks for the reference suggestions, RU.08 and Lasershwert. The more of these I can get the better!
