This file contains the code in the qtmain library for WinRT.
qtmain contains the WinRT startup code and is required for
linking to the Qt DLL.
When a Windows application starts, the WinMain function is
invoked. This WinMain creates the WinRT application
container, which in turn calls the application's main()
entry point within the newly created GUI thread.
