Subject: [PATCH] Use the API to insist SyncTERM is "High DPI aware"
Microsoft wants us to use a manifest for this, but I really don't
feel like digging into however one uses manifest files when not
using the Microsoft build files.
Details here: https://docs.microsoft.com/en-us/windows/win32/hidpi/setting-the-default-dpi-awareness-for-a-process
