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.

Whitespace in a makefile is consequential. In fact, it's part of the syntax. And at least a few versions of make puke on Makefiles with lines indented with spaces, not tabs. Obviously GNU make used on Debianish systems is not strictly among them, or this would fail. Even so, I cannot resist the urge to pedantically fix this, if only to get rid of the bright syntax error red coloration in vim. :)

test/testdrawchessboard.c checks out of hg with DOS line endings on non-dos systems. Fixed via:
perl -pi -e 's/\r//g' test/testdrawchessboard.c

The audio_enumerateAndNameAudioDevicesNegativeTests test in testautomation_audio.c reports a failure for SDL_GetAudioDeviceName when called on a driver that has only the default device. SDL_GetNumAudioDevices reports 1, but SDL_GetAudioDeviceName does not check if the index passed by the caller is in that range in this case. For positive numbers anyway.
This can be reproduced with the dummy driver on Windows and Linux.

I've recently tried to create multiple windows and process key events for them, and found that key events weren't being generated for most of the windows. After some investigating I've observed the following effects. All but the most recently created window experience these effects...
- a focus lost event is generated immediately after the focus gained event, even tho window still has focus
- key events report window id 0 rather than the id of the window which has focus, SDL thinks no window has focus?
- giving focus to a non SDL window and then selecting an SDL window causes events to be generated as expected, but only until focus changes again
Focus change events are queued and delayed (200 ticks) before they are dispatched. The problem occurs when a focus out and focus in event are received on the same tick. When these delayed events are dispatched they will be sent in the order determined by the window list rather than the order in which they are received.
The focus out dispatch is implemented by calling SDL_SetKeyboardFocus(NULL). This will remove focus from any window, regardless of whether it is the one originally targeted by the X11 event.
Since SDL_SetKeyboardFocus() will always dispatch a focus lost event as needed, the easiest solution is simply to only call SDL_SetKeyboardFocus(NULL) when SDL_GetKeyboardFocus() matches the target window.
The first bug had mouse motion events not getting sent out on non-touch devices, if and when a mouse button wasn't pressed.
The second bug caused virtual mouse motion events to get sent out-of-order on touch devices: the motion event would get sent after the touch occurred, rather than before.
To enable the Debug Layer, set the hint, SDL_HINT_RENDER_DIRECT3D11_DEBUG to '1'.
The Debug Layer will be turned off by default, both in Release and Debug builds (of SDL).

I actually made a mistake when creating the previous patch file... I forgot to include a crucial line which changed.
I've attached a new patch which just changes the line I forgot, since the other part has already been applied to the repository.
I tested this one by doing a clean rebuild of SDL, and it works with the new patch.

Reopening as compilation with ANSI C throws lots of unnecessary warnings, both using MinGW and using Linux GCC. (BTW, what happened? MinGW is broken to all hell. sdl2-config does not even link SDLMain anymore?)
I think this may have been lost somewhere, so again: GCC supports inlining via __inline__ in all known versions of GCC, regardless of the C standard in use. Please don't assume that __STRICT_ANSI__ implies no inlining support.

I was going through the SDL_IntersectRectAndLine function and wondered to see the ComputeOutCode function implementation.
The problem in this algo is, x and y axis are getting check with respect to 0, Which is wrong, it should be get checked with respect to rectangle x and y axis.

The recommended way of getting a file name that POSIX file APIs can open in OS X when using an NSString is -[NSString fileSystemRepresentation]. However, the current filesystem API in hg uses -[NSString UTF8String].
