Original change's description:
> custom typeface
> 
> - only paths implemented at the moment
> 
> Seems if we want to serialize/deserialize these, we will need to
> register a factory with skia, so it can sniff the beginning of the
> font "file", to know how to recreate it.
> 
> Lots of follow-on things to explore:
> - do we need to even store/know advance widths?
> - should we also (optionally) support a CMAP? names? others?
