      Many of the tests in 'reftests' may fail (over half in May 2021) because
      they produce, and then diff, graphic files with text and the details such
      as spacing vary when the system versions of cairo, freetype, pixman, pango
      and perhaps harfbuzz differ from the versions on the system where the
      reference files were created. For this reason, running the tests is not
      recommended.
      To test the results anyway, issue: <command>make check</command>.
