    \class QWindowsIntegration
    \brief QPlatformIntegration implementation for Windows.
    \internal

    \section1 Programming Considerations

    The platform plugin should run on Desktop Windows from Windows XP onwards
    and Windows Embedded.

    It should compile with:
    \list
    \li Microsoft Visual Studio 2013 or later (using the Microsoft Windows SDK,
        (\c Q_CC_MSVC).
    \li Stock \l{http://mingw.org/}{MinGW} (\c Q_CC_MINGW).
        This version ships with headers that are missing a lot of WinAPI.
    \li MinGW distributions using GCC 4.7 or higher and a recent MinGW-w64 runtime API,
        such as \l{http://tdm-gcc.tdragon.net/}{TDM-GCC}, or
        \l{http://mingwbuilds.sourceforge.net/}{MinGW-builds}
        (\c Q_CC_MINGW and \c __MINGW64_VERSION_MAJOR indicating the version).
        MinGW-w64 provides more complete headers (compared to stock MinGW from mingw.org),
        including a considerable part of the Windows SDK.
    \endlist

    When using a function from the WinAPI, the minimum supported Windows version
    and Windows Embedded support should be checked. If the function is not supported
    on Windows XP or is not present in the MinGW-headers, it should be dynamically
    resolved. For this purpose, QWindowsContext has static structs like
    QWindowsUser32DLL and QWindowsShell32DLL. All function pointers should go to
    these structs to avoid lookups in several places.
