    Description

      The Windows platform plugin currently uses SetProcessDpiAwareness to set the dpiAwareness level. Newer Windows versions (Windows 10, 1703) have a function SetProcessDpiAwarenessContext which supports another value DPI_AWARENESS_CONTEXT_PER_MONITOR_AWARE_V2. This will enable window decoration and native dialog scaling on mixed-monitor setups, so this should be the default on appropriate systems.

      The dynamic size changes of window decorations and dialogs probably need to be handled in Qt.
