2. Fix the wrong coordinate of the right and bottom frame border of the widget example.
3. Improve the Qt Quick example.
4. Correctly detect the OS version when building against Qt below 5.9.
5. Other minor tweaks.

1. The QWinRegistryKey class was introduced in 5.14.0. The implementation is quite clean, so just copy the sources files from Qt repo in case the user is linking against a version older than 5.14.
2. Fixes the rounding error of the self-painted frame border of the examples.
3. Other minor tweaks.
