- SDL_WINDOW_FULLSCREEN works as always (change resolution, lock to window).
- SDL_WINDOW_FULLSCREEN_DESKTOP now puts the window in its own Space, and
hides the menu bar, but you can slide between Spaces and Command-Tab between
apps without the window minimizing, etc.
- SDL_WINDOW_RESIZABLE windows will get the new 10.7+ "toggle fullscreen"
window decoration and menubar item. As far as the app is concerned, this is
no different than resizing a window, but it gives the end-user more power.
- The hint for putting fullscreen windows into the Spaces system is gone,
since Spaces can't enforce the requested resolution. It's a perfect match
for FULLSCREEN_DESKTOP, though, so this is all automated now.
configure wraps this C code in a main() function, so you can't declare a
function body in there. Besides, I'm not sure why we declared a function
that's part of the multitouch API anyhow.
Now we just reference a type that only exists if the headers have multitouch
support and call it a day.

A customer of mine had the strange problem, that SDL_SetRelativeMouseMode() was failing for him on Windows 7. Luckily he was willing to provide some debug informations. We could track this problem down to RegisterRawInputDevices() failing due to security software running on his system (Norton Internet Security to be precise, but there are reports of similar problems with other products. For example [1]). Working around this issue with SDL_WarpMouseInWindow() is easy, and while I don't think that SDL2 can provide an internal workaround it would be really nice and helpfull if this could be documentated somewhere.

In src\timer\windows\SDL_systimer.c there is an error with regards to timeBeginPeriod and timeEndPeriod. These functions typically get called when no high resolution timer is available, and GetTickCount is not used.
According to MSDN (link: http://msdn.microsoft.com/en-us/library/windows/desktop/dd757624(v=vs.85).aspx), for every call to timeBeginPeriod a subsequent call to timeEndPeriod is required. While SDL is currently doing this, it fails to call timeEndPeriod when cleaning up/shutting down SDL. Please note that these functions affect things on a system level. Failing to call timeEndPeriod, disables applications for using WINMM-timers after usage&shutdown of SDL, as effectively they the mechanism is now broken.
Solution:
Ensure this code gets called when shutting down the timer subsystem:
#ifndef USE_GETTICKCOUNT
if (!hires_timer_available)
{
timeSetPeriod(0);
}
#endif
This makes it possible to move windows by their title bar, even if they're in
relative mode, if you click the title bar when the window does not have focus.

Previously we were postponing our -[NSOpenGLContext update] call to the next
SDL_GL_SwapWindow, even if the context was current on the current thread. This
changes it so that we will do the update immediately if it's the current
context.
If you're rendering on another thread, you need to call SDL_GL_SwapWindow once
after a resize event to ensure your drawable will produce non-garbage data.

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.
Due to the new "tap and hold" IME in Mountain Lion and above, we were getting
inconsistent repeat of SDL_TEXTINPUT events. Disabling that functionality (since
you can't see the popover anyway) solves this.

The DualShock 4 has all elements listed twice: once in the top-level list of
elements, and once in an "Application Collection" element at the top-level.
Each element has a proper cookie with a unique value, so now we descend into
each element collections, but before we add an element to the device's list,
we make sure we don't already have one with that cookie, probably from
another collection or a buggy device.

All CPU detection functions SDL_Has* will return false, even if it is supported by the CPU, if SDL is compiled with MSVC and the target is x64.
The reason for this is that 'CPU_haveCPUID' will return 0 and macro 'cpuid' in SDL_cpuinfo.c is the fallback implementation, which sets all params to zero.
It is safe to assume that cpuid is supported on a CPU that runs windows x64, so CPU_haveCPUID can just return 1, and the empty macro can be replaced with a small wrap around the __cpuid intrinsic.
