  21  *
  22  * Qt <= 5.9 supports setting old (Windows 8.1) per-monitor DPI awareness
  23  * via Qt:AA_EnableHighDpiScaling. We do this in main.cpp. In order for
  24  * native dialogs to be rendered correctly we need to set per-monitor
  25  * *v2* awareness prior to creating the dialog, which we can do here.
  26  * Qt < 5.14(?) or so doesn't render correctly when per-monitor v2 awareness
  27  * is enabled, so we need to revert our thread context when we're done.
  28  * Qt >= 6.0 is per-monitor DPI awareness v2 by default, so this doesn't
  29  * have any effect.
  30  *
  31  * @return The current thread DPI awareness context, which should
  32  * be passed to revert_thread_per_monitor_v2_awareness.
