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.
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.

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.
