Subject: [PATCH] Support larger font scaling

.. as 8k displays become more popular and affordable we need to
   support greater font scaling - we now scale up to x5 the
   default font size

   This should be good for devices well over 8k resolution but
   does highlight some limitations with Qt widgets and maximum
   sizes they support internally.
