    <!-- Due to patent (http://freetype.sourceforge.net/patents.html)
         issues hinting gives different results depending on the
         freetype version of the linux distribution, avoiding hinting
         gives more consistent results. When all the distributions
         release freetype the 2.4, which enables by default the
         hinting method that was patented, we could undo this change
         and try the hinting again. -->
