It simplifies the API and reduces surprise to have rotation working by default.
On Android, the manifest specifies which orientations the application has
been designed to support; on iOS, it is controlled via the
UISupportedInterfaceOrientations property list key.
In addition, QWindow::contentOrientation() is another way to give
a hint to the window manager, or on iOS to directly control whether
the window's rotation is locked or not.
