For 2017, we want to overhaul the vector system. The current vector system is ODG based, and it should become fully SVG based. There is already a bunch of SVG code in flake. An alternative to SVG would be to try and support PSD's vector implementation, but I'm not in favor of that.
- Having separate vector layers is fine.
- This will cause a file compatibility break. Old vector layers will no longer be loadable! We need to create a conversion tool.
