  # Qt: workaround for determinism in resource ordering
  #  Qt5's rcc uses a QHash to store the files for the resource.
  #  A security fix in QHash makes the ordering of keys to be different on every run
  #  (https://qt.gitorious.org/qt/qtbase/commit/c01eaa438200edc9a3bbcd8ae1e8ded058bea268).
  #  This is good in general but qrc shouldn't be doing a traversal over a randomized container.
  #  The thorough solution would be to use QMap instead of QHash, but this requires patching Qt.
  #  For now luckily there is a test mode that forces a fixed seed.
