Attributes on the host device's rotation were getting applied to offscreen
textures in an invalid manner. This was causing some apps to look different,
depending on how the device was rotated.

If a Windows Phone 8.1 device was rotated to anything but Portrait mode,
the Direct3D 11 renderer's output wouldn't get aligned correctly with the
screen.
This fixes an issue where an empty cliprect is treated the same as a NULL
cliprect, causing the render backends to disable clipping.
Also adds a new API, SDL_RenderIsClipEnabled(render) that allows you to
differentiate between:
- SDL_RenderSetClipRect(render, NULL)
- SDL_Rect r = {0,0,0,0}; SDL_RenderSetClipRect(render, &r);

I encountered a little issue: DXGI monitors application's message queue and this behavior interferes with SDL if the application already handles Alt-Enter sequence. I think it is necessary to disable this behavior.

These scenarios can happen when a GPU is switched, its driver updated, or in
some virtual machines (such as Parallels) are suspended and then resumed. In
these cases, all GPU resources will already be lost, and it's up to the app to
recover.
For now, SDL's D3D11 renderer will handle this by freeing all GPU resources,
including all textures, and then sending a SDL_RENDER_TARGETS_RESET event.
It's currently up to an app to intercept this event, destroy all of its
textures, then recreate them from scratch.
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).
Still TODO: fix other build errors, especially linker errors, when building
SDL/WinRT, then fix any runtime errors that pop up.

This change is currently limited to Win32/Windows-Desktop builds. Build fixes
for WinRT + VS2012 are still pending.

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.
