  [X11] Reconcile logical keyboard state with physical state on FocusIn
  since the window system doesn't do it for us like other platforms.
  
  This prevents sticky keys and missed keys when going in and out
  of focus, for example Alt would appear to stick if switching away
  from an SDL app with Alt-Tab and had to be pressed again.

  /* At least one file in any SDL/WinRT app appears to require compilation
     with C++/CX, otherwise a Windows Metadata file won't get created, and
     an APPX0702 build error can appear shortly after linking.
  
     The following set of preprocessor code forces this file to be compiled
     as C++/CX, which appears to cause Visual C++ 2012's build tools to
     create this .winmd file, and will help allow builds of SDL/WinRT apps
     to proceed without error.
  
     If other files in an app's project enable C++/CX compilation, then it might
     be possible for SDL_winrt_main_NonXAML.cpp to be compiled without /ZW,
     for Visual C++'s build tools to create a winmd file, and for the app to
     build without APPX0702 errors.  In this case, if
     SDL_WINRT_METADATA_FILE_AVAILABLE is defined as a C/C++ macro, then
     the #error (to force C++/CX compilation) will be disabled.
  
     Please note that /ZW can be specified on a file-by-file basis.  To do this,
     right click on the file in Visual C++, click Properties, then change the
     setting through the dialog that comes up.
