Rotation detection and handling should now work across all, publicly-released,
WinRT-based platforms (Windows 8.0, Windows 8.1, and Windows Phone 8.0).
This changeset prevents IDXGISwapChain::ResizeBuffers from being invoked on
Windows Phone 8, a function that isn't available on the platform (but is
available on other Windows platforms). The call would fail, which ultimately
led to a crash.
This changeset also attempts to make sure that the D3D11 swap chain is created
at the correct size, when using Windows Phone 8.
Still TODO: make sure rotation-querying works across relevant Windows
platforms (that support Direct3D 11.x).
The D3D11 renderer is now slightly faster than D3D9 on my Windows 8 machine (testsprite2 runs at 3400 FPS vs 3100 FPS)
This will need tweaking to fix the Windows RT build.
If the window has been created with values for SDL_GL_CONTEXT_PROFILE_MASK,
SDL_GL_CONTEXT_MAJOR_VERSION and SDL_GL_CONTEXT_MINOR_VERSION not matching those
required by the renderer, attempt to recreate the window.
This is needed on platforms where both GL and GLES 1/2 surfaces are supported
by the video backend, requiring that the window be recreated when switching
between context types.
The destination target's alpha wasn't getting set correctly in many cases. Among other problems, this prevented some alpha-blended textures from displaying correctly in Windows Phone 8's multitasking screen.
The d3d11 renderer now uses the same blending settings found in the d3d9 renderer.
The projection and view matrices are now computed ahead of time, as they both get computed in the same spot, and typically not often. If this does, however, become a performance problem later on, this change can always be reverted.
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.

I'm unable to compile the latest SDL (directly from the repository) even though I disabled every DirectX option since I don't need DirectX.
I allways het these errors:
D:\DevLibs\SDL\src\render\direct3d\SDL_render_d3d.c:1897:1: error: unknown type name 'IDirect3DDevice9'
D:\DevLibs\SDL\src\render\direct3d\SDL_render_d3d.c:1898:25: error: unknown type name 'SDL_Renderer'

SDL_RenderClear clears a render target with the wrong color, if the opengles2 renderer driver is used and the target texture's format is SDL_PIXELFORMAT_ARGB8888.
The bug is *not* reproduced if SDL_PIXELFORMAT_ABGR8888 is used as the texture format (the first from the renderer's list).
It is further not reproduced using any of the following renderer drivers: opengl, opengles (apparently powered by Gallium3D), software.
Finally, the correct color can be drawn using SDL_RenderFillRect (instead of SDL_RenderClear).
A few details about the current setup:
- OS: Ubuntu 12.04 for x86_64
- GPU: GeForce GTX 460
- GPU driver version: 331.20-0ubuntu1~xedgers~precise1 (from the xorg-edgers PPA)

Sam,
It appears that the clear just needs to take the render target format into consideration.
