Windows CE is no longer supported by SDL.



We have left the CE support in SDL 1.2 for those that must have it, and we

will accept patches that support more modern Windows Mobile platforms for

SDL 2.0.

have support for Windows Phone 8 and WinRT in SDL2, as of SDL 2.0.3.

/* WinRT NOTICE:

   A few changes to SDL's XAudio2 backend were warranted by API
   changes to Windows.  Many, but not all of these are documented by Microsoft
   at:
   http://blogs.msdn.com/b/chuckw/archive/2012/04/02/xaudio2-and-windows-8-consumer-preview.aspx

   1. Windows' thread synchronization function, CreateSemaphore, was removed
      from WinRT.  SDL's semaphore API was substituted instead.
   2. The method calls, IXAudio2::GetDeviceCount and IXAudio2::GetDeviceDetails
      were removed from the XAudio2 API.  Microsoft is telling developers to
      use APIs in Windows::Foundation instead.
      For SDL, the missing methods were reimplemented using the APIs Microsoft
      said to use.
   3. CoInitialize and CoUninitialize are not available in WinRT.
      These calls were removed, as COM will have been initialized earlier,
      at least by the call to the WinRT app's main function
      (aka 'int main(Platform::Array<Platform::String^>^)).  (DLudwig:
      This was my understanding of how WinRT: the 'main' function uses
      a tag of [MTAThread], which should initialize COM.  My understanding
      of COM is somewhat limited, and I may be incorrect here.)
   4. IXAudio2::CreateMasteringVoice changed its integer-based 'DeviceIndex'
      argument to a string-based one, 'szDeviceId'.  In WinRT, the
      string-based argument will be used.

   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.

   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

    // Simulator, as well as Windows 8 in a Parallels 8 VM, MouseEventArgs'
    // MouseDelta field often reports very large values.  More information
    // on this can be found at the following pages on MSDN:
    //  - http://social.msdn.microsoft.com/Forums/en-US/winappswithnativecode/thread/a3c789fa-f1c5-49c4-9c0a-7db88d0f90f8
    //  - https://connect.microsoft.com/VisualStudio/Feedback/details/756515
    //
    // The values do not appear to be as large when running on some systems,
    // most notably a Surface RT.  Furthermore, the values returned by
    // CoreWindow's PointerMoved event, and sent to this class' OnPointerMoved
    // method, do not ever appear to be large, even when MouseEventArgs'
    // MouseDelta is reporting to the contrary.
    //
    // On systems with the large-values behavior, it appears that the values
    // get reported as if the screen's size is 65536 units in both the X and Y
    // dimensions.  This can be viewed by using Windows' now-private, "Raw Input"
    // APIs.  (GetRawInputData, RegisterRawInputDevices, WM_INPUT, etc.)
    //
    // MSDN's documentation on MouseEventArgs' MouseDelta field (at
    // http://msdn.microsoft.com/en-us/library/windows/apps/windows.devices.input.mouseeventargs.mousedelta ),
    // does not seem to indicate (to me) that its values should be so large.  It
    // says that its values should be a "change in screen location".  I could
    // be misinterpreting this, however a post on MSDN from a Microsoft engineer (see: 
    // http://social.msdn.microsoft.com/Forums/en-US/winappswithnativecode/thread/09a9868e-95bb-4858-ba1a-cb4d2c298d62 ),
    // indicates that these values are in DIPs, which is the same unit used
    // by CoreWindow's PointerMoved events (via the Position field in its CurrentPoint
    // property.  See http://msdn.microsoft.com/en-us/library/windows/apps/windows.ui.input.pointerpoint.position.aspx
    // for details.)
    //
    // To note, PointerMoved events are sent a 'RawPosition' value (via the
    // CurrentPoint property in MouseEventArgs), however these do not seem
    // to exhibit the same large-value behavior.
    //
    // The values passed via PointerMoved events can't always be used for relative
    // mouse motion, unfortunately.  Its values are bound to the cursor's position,
    // which stops when it hits one of the screen's edges.  This can be a problem in
    // first person shooters, whereby it is normal for mouse motion to travel far
    // along any one axis for a period of time.  MouseMoved events do not have the
    // screen-bounding limitation, and can be used regardless of where the system's
    // cursor is.
    //
    // One possible workaround would be to programmatically set the cursor's
    // position to the screen's center (when SDL's relative mouse mode is enabled),
    // however WinRT does not yet seem to have the ability to set the cursor's
    // position via a public API.  Win32 did this via an API call, SetCursorPos,
    // however WinRT makes this function be private.  Apps that use it won't get
    // approved for distribution in the Windows Store.  I've yet to be able to find
    // a suitable, store-friendly counterpart for WinRT.
    //
    // There may be some room for a workaround whereby OnPointerMoved's values
    // are compared to the values from OnMouseMoved in order to detect
    // when this bug is active.  A suitable transformation could then be made to
    // OnMouseMoved's values.  For now, however, the system-reported values are sent
    // to SDL with minimal transformation: from native screen coordinates (in DIPs)
    // to SDL window coordinates.
