commit 1aa8b700c3f09a31c78e7834e0db373f80b5e226
Author: Akira TAGOH <akira@xxxxxxxxx>
Date:   Tue Oct 2 09:32:03 2018 +0000

    Add more prefix support in <dir> element
    
    Added two prefix modes:
      "relative" that makes the relative path be relative to current file
      "cwd" for relative to current working directory which implies current behavior.
    
    Resolves: https://gitlab.freedesktop.org/fontconfig/fontconfig/issues/15
