      Description

      JalviewJS/SwingJS rendered views appear blurry on Chrome/OSX (and others) due to the browser's HiDPI autoscaling feature: https://www.html5rocks.com/en/tutorials/canvas/hidpi/

      Possibly need a patch to SwingJS to scale each Graphics div to ensure 1:1 pixel match with image backing store.
