Eelco Dolstra d051b20a39 * Graphviz updated to 2.20.2. Now built with fontconfig, gd and pango
support.
* New function makeFontsConf to generate a fontconfig configuration
  file.  Moved from NixOS.
* dot2pdf: use makeFontsConf to generate a fonts.conf containing just
  the Ghostscript fonts (see NIXPKGS-29).
* dot2pdf: generate PDF directly, don't go through PS.  Note that this
  and using fontconfig changes the interpretation of "fontname"
  attributes in dot graphs.
