    Description

      We need a QWindowsDirectWriteFontDatabase which does not use any GDI APIs and only creates DirectWrite font engines.

      Ideally this will be the only font database in Qt 6, but lets see. It has some implications to which Windows versions will be supported (minimum version Windows 7 it seems, not sure if platform update is needed).

      Most likely this will improve several things related to font matching and also reduce our maintenance load significantly.
