XAudio2 doesn't have capture support, so WASAPI was to replace it; the holdout
was WinRT, which still needed it as its primary audio target until the WASAPI
code code be made to work.
The support matrix now looks like:
WinXP: directsound by default, winmm as a fallback for buggy drivers.
Vista+: WASAPI (directsound and winmm as fallbacks for debugging).
WinRT: WASAPI

New functions get and set the YUV colorspace conversion mode:
SDL_SetYUVConversionMode()
SDL_GetYUVConversionMode()
SDL_GetYUVConversionModeForResolution()
SDL_ConvertPixels() converts between all supported RGB and YUV formats, with SSE acceleration for converting from planar YUV formats (YV12, NV12, etc) to common RGB/RGBA formats.
Added a new test program, testyuv, to verify correctness and speed of YUV conversion functionality.
According to Steam's OS stats, Windows 8.0 use is pretty much nil. Further,
Microsoft hasn't support Windows 8.0 development in any of their
actively-updated toolchains, and setting it up can be a pain.
In theory, SDL2 still supports Windows 8.0, however building of Windows 8.0
.dlls is no longer the default, if and when using the 'winrtbuild.*' scripts.
The MSVC 2012 project files for building Windows 8.0 dlls remain, though,
for the time being.
These fixes are lumped into two categories:
1. add new file, SDL_dataqueue.c, to UWP/WinRT build-inputs (via MSVC project
files)
2. implement a temporary, hack-fix for a build error in SDL_xinputjoystick.c.
Win32's Raw Input APIs are, unfortunately, not available for use in UWP/WinRT
APIs. There does appear to be a replacement API, available in the
Windows.Devices.HumanInterfaceDevice namespace.
This fix should be sufficient to get SDL compiling again, without affecting
Win32 builds, however using the UWP/WinRT API (in UWP/WinRT builds) would
almost certainly be better (for UWP/WinRT builds).
TODO: research Windows.Devices.HumanInterfaceDevice, and use that if and as
appropriate.
The repro steps were this:
1. run an sdl2 winrt/uwp app, on Win10, v10.0.10586.0 or higher
2. hide the cursor, via a call to SDL_ShowCursor(0)
3. make the Win10 game bar appear, by pressing the Windows + G hotkey
4. observe that the mouse cursor appears, in order to interact with the
game bar (this is expected behavior)
5. make the Win10 game bar disappear, either by pressing the Windows + G hotkey
again, or clicking somewhere in the app
EXPECTED RESULT: cursor disappears, as game bar disappears
ACTUAL RESULT: cursor didn't always disappear

I think this was important for SDL 1.2 because some targets needed
special device memory for DMA buffers or locked memory buffers for use in
hardware interrupts or something, but since it just defines to SDL_malloc
and SDL_free now, I took it out for clarity's sake.

"UWP" appears to be Microsoft's new name for WinRT/Windows-Store APIs.
This set of changes updates SDL's WinRT backends to support the Win10 flavor
of WinRT. It has been tested on Win10 on a desktop. In theory, it should
also support Win10 on other devices (phone, Xbox One, etc.), however further
patches may be necessary.
This adds:
- a set of MSVC 2015 project files, for use in creating UWP apps
- modifications to various pieces of SDL, in order to compile via MSVC 2015 +
the Win10 API set
- enables SDL_Window resizing and programmatic-fullscreen toggling, when using
the WinRT backend
- WinRT README updates
WinRT 8.0 (Phone and non-Phone) didn't offer an API to set an already-created
thread's priority. WinRT 8.1 offered this API, along with several other
Win32 thread functions that were previously unavailable (in WinRT).
This change makes WinRT 8.1+ platforms use SDL's Win32 backend.
The "future-dev" branch of MSOpenTech's ANGLE/WinRT repository (at
https://github.com/msopentech/angle) includes support for Windows Phone 8.1.
This change allows it to be used in conjunction with SDL's OpenGL functions.
Notes:
- Support for the 'Guide' button does not seem to be possible, as
XInputGetStateEx is not available on WinRT.
- Haptic support appears to be working on WinRT now!
- SDL/WinRT does not allow calls to LoadLibrary or LoadLibraryEx. The calls
to those were removed by this change, but only when compiling for WinRT.
Non-WinRT Windows will continue to detect and load XInput via LoadLibrary and
GetProcAddress calls.
This change removes the "Shared" component from the Windows 8.1 and Windows
Phone 8.1 project files, then renames the projects to use a file structure
that's the same as used for the Windows 8.0 and Windows Phone 8.0 projects.
This change now places WinRT projects in the following directories:
VisualC-WinRT\WinRT81_VS2013\ -- Windows 8.1 project files
VisualC-WinRT\WinPhone81_VS2013\ -- Windows Phone 8.1 project files (NEW, as of this change)
VisualC-WinRT\WinRT80_VS2012\ -- Windows 8.0 project files
VisualC-WinRT\WinPhone80_VS2012\ -- Windows Phone 8.0 project files
Windows 8.0 and Windows Phone 8.0 projects, as well as apps or libs that
reference these, should be unaffected by this change.
Windows 8.1 and Windows Phone 8.1 based apps or libs that reference SDL's
projects directly will need to have their old references removed, then
replaced with new ones that point to the updated structure.
This is a step towards supporting "Universal" Windows apps, when building for
Windows Phone. SDL can now build against the Windows Phone 8.1 SDK, and apps
linked to it can run, however further work and testing is required as some
previously Phone-only code appears to no longer be applicable for
Windows Phone 8.1. The Windows 8.1 code paths does seem to be preferable, but
should probably be tested and updated on a finer-grained basis.
If in doubt, use the Windows Phone 8.0 projects for now, as located in
VisualC-WinRT/WinPhone80_VS2012/
TODO:
- look at any Windows Phone specific code paths in SDL, and see if Phone 8.1
should use the Windows Phone code path(s), or the Windows 8.x or 8.1 paths
This commit also includes some base-level support for Universal apps.
TODO:
- add support for Windows Phone 8.1
- add support for satellite libs: SDL_image, SDL_ttf, and SDL_mixer

All WinRT projects have been merged into a single directory, "VisualC-WinRT",
with platform-specific variants in subdirectories off of it. This structure
has been applied to a few major SDL satellite libraries as well (SDL_image,
SDL_mixer, and SDL_ttf).
Currently, only Windows 8.0/RT and Windows Phone 8.0 targets are supported.
Windows 8.1/RT/Phone targets are planned.
Projects that use SDL_image/WinRT, and link to it via Visual Studio's
project-to-project reference system, will need to be updated, to reflect the
changes in the project structure. This can be done by:
1. removing the MSVC project(s) for SDL/WinRT
2. re-added the MSVC project(s) for SDL/WinRT
3. right-clicking on the app, or projects that use those libraries, choosing
References, removing the references to any of these projects (they'll likely
be highlighted with an exclamation mark), then re-adding them
To note, the satellite libraries that reference SDL/WinRT have been updated
already. The changes for those libraries will be pushed to hg.libsdl.org
shortly.
TODO:
- add support for Windows 8.1 and Windows Phone 8.1 targets, using
Microsoft's new "Universal" app support, if possible. These will be added to
a new subdirectory, or subdirectories (if more than one sets of projects are
needed, hopefully not), of "VisualC-WinRT".
- investigate NuGet support, which could allow Visual C++ to download
new copies of SDL/WinRT, its satellite libraries, and their dependencies,
from remote servers.
All WinRT builds of SDL will now output, "SDL2.dll". Previously, the Windows
8.x/RT builds would output, "SDL.dll", and Windows Phone 8 builds would output,
"SDL_WinPhone.dll". The change to "SDL2.dll" puts WinRT dll naming in-line with
that seen on Win32.
SDL/WinRT's MSVC project files will now appear as either "SDL2-WinRT" or
"SDL2-WinPhone", when displaying in MSVC.
This set of changes should not break any older WinRT or Windows Phone 8 app
builds that rely on MSVC's Project-to-Project reference system to build SDL2 for
the correct platform(s), and to install SDL2 dll files into the apps' output
packages. App builds that reference SDL dll files directly should, however,
now reference "SDL2.dll".

SDL/WinRT did have support for OpenGL ES 2 via an older version of ANGLE/WinRT,
however its API changed a few months ago, and SDL/WinRT would crash when trying
to use it. It would also occasionally crash when using the older version.
This changeset should make SDL/WinRT work with the latest version, as
available via MS Open Tech's git repository of it at
https://github.com/msopentech/angle
Older versions of ANGLE/WinRT (from either https://github.com/stammen/angleproject
or https://bitbucket.org/DavidLudwig/angleproject) will need to be updated to

Previously, the shaders would get compiled separately, the output of which would need to be packaged into the app. This change should make SDL's dll be the only binary needed to include SDL in a WinRT app.
A port of the ANGLE library (OpenGL ES 2.0 for Direct3D) to WinRT, via https://github.com/stammen/angleproject, is used as a base.
To enable, clone 'angleproject' into the directory one above where SDL/WinRT is, open the file SDL/include/SDL_config_winrt.h, and uncomment the #defines that begin with 'SDL_VIDEO_OPENGL'. From there, apps can create an OpenGL capable SDL_Window via the flag, SDL_WINDOW_OPENGL, and an OpenGL ES 2 context via SDL_GL_CreateContext. The Direct3D 11.1 renderer cannot be used alongside SDL_WINDOW_OPENGL. Only Windows 8/8.1 is supported for now. Shaders may need to be precompiled, in some (all?) cases.
This can break builds of existing SDL/WinRT apps. To fix, remove the reference to SDL_winrt_main.cpp, then add a reference to the renamed file, SDL_winrt_main_NonXAML.cpp. If you get a build error about a missing .winmd file, enable the /ZW compiler flag for that one file (at minimum).

1. remove references to SDL's project files from the Visual Studio Solution. To note, these project files have been renamed, and will show up in Visual Studio with the text, "load failed".
2. add the SDL project files back into the Visual Studio Solution
3. for each project that should link to SDL, add a reference to it. This can be done by right-clicking on it in Visual Studio, selecting "References...", clicking "Add New Reference", checking the box next to the SDL project, then closing each dialog by clicking OK.
SDL_mixer, SDL_ttf, and SDL_image for WinRT have been updated, and will be pushed to my Bitbucket repos with these changes having been made. If you do not pull in these changes, be sure to re-add to them the reference to the SDL project, as described above.

XAudio2 2.8's header file, xaudio2.h, doesn't compile in plain C code for WinRT
apps, not automatically at least. Initially, this file was adapted to compile
as C++, however these changes are now deprecated in favor of some preprocessor
based hacks that should get xaudio2.h to compile (while making sure XAudio2
still works).
