We want for each of them to fallback to any of these available,
but in an order preferring similar designs first.  We do this in three steps:

1) Alias each specific to its generic family.
   e.g. Liberation Sans to Arial

2) Weak alias each generic to the other generic of its family.
   e.g. Arial to Helvetica

3) Alias each generic to its specifics.
   e.g. Arial to Liberation Sans, Arimo, Albany, and Albany AMT

NOTE: The (URW)++ fonts mappings of generics to specifics were removed, because
      upstream now includes them in their release of (URW)++ Core Font Set here:
      https://github.com/ArtifexSoftware/urw-base35-fonts/tree/master/fontconfig
