chrisl: "It would probably be good to augment the Fontmap code to allow TTC entries to be loaded as font substitutes ...at some point" (2015-04-02, CEST=11:17:13h, in #ghostscript IRC). This is just a reminder entry into Bugzilla to help this idea to not be forgotten :)
In addition, we should also allow the cidfmap file to be specified on the command line (i.e. "-sCIDFMAP=<path to file>") as the Fontmap file currently can be.
