A very good example of SDF thinking, using signed distance fields in shaders. Both shaders and SDF are new to me and very interesting. Another example of what is being done is MSDF here: https://github.com/Chlumsky/msdfgen.
That what I wondering, for sharp narrow corners like with that pac-man mouth center and in font rendering composite/multichannel is probably the better approach for any situation where the there is potential for self-intersection of the distance field in concave situations.
