This will be a "complete rewrite" so to speak as I normalize all of the symbols and remove the width cap that the glyphs have had previously. Currently very tall/skinny or very flat/narrow symbols look disproportionate compared to circle- or square-shaped ones. These glyphs need to be wider so that visually all of the symbols appear to be the same size.

The other major upgrade is that dual-layered symbols will all be properly supported. Updates to all of the existing glyphs with new svg guidelines included, as well as some improvements to the way borders are handled.
