Move UI icons to a UFO file in the resources directory

An idea from a discussion in this pull request: #247

Would it be possible to load icons from a UFO file in the resources directory? Currently, I am drawing the icons in Runebender and pasting them into the toolbar.rs file (see the screenshot below).

I have a git repo for the icon UFOs I have worked with so far here. It might be nice to just add a UFO like this to the resources directory so an external repo isn't needed to track these files.

Definitely the right move, the actual icon source that a developer could tweak without starting from scratch should not be in a separate repository ;-)

Since toolbar icons aren't a full fledged font and don't need kerning or OpenType features or anything, perhaps storing a full UFA isn't necessary and just bare .glif files would be enough.

Being able to edit detached (unparented) .glif files is a must if you ask me, but I'm trying not to comment here too much given that I, you know, am the BD of a competing project. ;-)

There is some further discussion about this going on here: #248

I haven't tried it myself, but @ctrlcctrlv's idea about loading just .glif files in the editor seems like it would work well for this.

I agree this makes total sense. I also think individual glif files is a nice idea; I've been thinking it would be nice to try and keep the coupling between runebender and the UFO format a little bit loose, and supporting some basic non-UFO cases is a good way to force that, and individual glif files would be a very simple way to do that, maybe?
