All SDL_* functions are always available as real symbols, so you can always
link against them as a stable ABI. By default, however, all the things that
might have dithered down to macros in your application are now force-inlined,
to give you the same effect as before and theoretically better performance,
but still solve the classic macro problems.
Elsewhere, we provide real functions for these things that simply wrap the
inline functions, in case one needs to have a real function available.
Also: this exposed bugs: SDL_abs() does something different if you had the
macro vs the libc function, SDL_memcpy() returns a void* in the function
but not the macro, etc.
- add mappings after init (or even before w/o using the hint)
- get string for axis
- get string for button
- get mapping string for controller or for GUID
- new event to notify when a controller is remapped. (e.g. mapping was changed via the AddMapping method)
* Normalized touch coordinates as floats in the 0...1 range
* Removed unused touchpad concepts from the API
* Added API functions to get active touch devices and current finger state
- Updated Visual Studio 2010 project with SDL 2.0 library names
- Don't use a 256 byte LUT, but rather <32 bytes of data on the stack.
- Cleanups in SDL_gamecontroller.h

- Fixes bug 1712 by not overwriting SDL_SubsystemRefCount in SDL_Init.
- Removes the SDL_initialized variable, and makes SDL_SubsystemRefCount
the canonical source of truth for whether or not a subsystem has been
initialized.
- Refactors SDL_InitSubSystem and SDL_QuitSubSystem to use helper
functions to manage refcount.
- Adds automated tests for SDL_Init/Quit*.
- Adds SDL_bits.h which contains SDL_MostSignificantBitIndex.
- Added new SDL_HINT_ALLOW_TOPMOST hint, when set to "0" then never set the topmost bit on a window. Useful when debugging fullscreen issues.
- fixed crash in windows joystick scanning if we failed to load the xinput dll
- added support for SDL_WINDOW_FULLSCREEN_DESKTOP under windows
- synthesize relative mouse movements if directinput fails to send relative moves, happens under virtual box.
