This should reduce unnecessary hardware interrupts. Apparently improves the
ALSA target on some systems.
Fixes Bugzilla #1170.

The license on IOHIDLib.h says we have to distribute a copy of the APSL with
every copy of SDL, and include a "prominent notice" in the documentation, and
that's annoying for something that's only there because Apple forgot to copy
a file in an ancient SDK.

branch : SDL-1.2
The new behavior is triggered by setting the environment variable
SDL_FBCON_DONT_CLEAR.
This is useful in certain circumstances (specifically: a game launcher on an
embedded device can leave a "now loading!" screen on the framebuffer while
another process is starting up).
Fixes Bugzilla #1251.

I'm not sure if there was a way to make CGLSetFullScreen() work, but the
Cocoa path works fine on all Intel Macs.
Please note that the "official" way to do fullscreen in 10.7 is just to make
a window the size of the display mode, and OS X is now smart enough to
recognize this as "fullscreen", but this helps earlier versions of the OS in
any case.

"Centering" is a little off-center, vertically. Apparently in non-fullscreen
apps, this is more aestetically pleasing or something.
Fixes positioning on fullscreen video modes on Mac OS X.

Mac OS X Lion (10.7) always returns NULL from CGDisplayBaseAddress(), so all
the direct framebuffer access code has been replaced with something a little
higher level. This also necessitated taking out the scary SDL_DOUBLEBUF
codepath that was trying to time out vsync by hand. :)

Newer kernels seem to report bogus axes in the higher ranges, for example
with a standard PlayStation 3 controller plugged in via USB.

Apparently these pointers can change if the user has multiple displays and
moves a window between them, and probably other similar cases.

If application installs SIGINT/SIGTERM signal handler with
sigaction(SA_SIGINFO) syscall before initializing SDL, after
initialization
of SDL signal handler will be reinstalled without SA_SIGINFO flag which
brings havoc when the signal handler is called. The breakage is done by
SDL_QuitInit()/SDL_QuitQuit() function. They use signal() to detect that
signal handler is already installed even in sigaction() is available.

Using SDL_VIDEO_CENTERED in Linux OpenGL mode issue an unwanted
ConfigureNotify event *after* the SDL screen has already been resized.
When going from a smaller to a larger screen, this event causes the mouse
tracking to be clamped at the *smaller* screen size, even though that
screen no longer exists.
The fix is to not issue a ConfigureNotify when the window is moved because
of the SDL_VIDEO_CENTERED environment variable. The included patch fixes
this bug. It seems the hints must be set before the window is moved.

nasm-2.09 makes `elf' alias to `elf32', thus __OUTPUT_FORMAT__ macro
becomes `elf32' instead of `elf' (on x86). Unmatched macro value causes
omitting .note.GNU-stack marker and creates ELFs with executable stack.
This is unneeded and attracts security policies like SELinux.

Currently SDL_JOYSTICK_DEVICE environment variable can be used to add
exactly one topmost device. I think it would be nice if one could also set
several devices (e.g. a stick and a throttle) in this way, as a colon-
separated list. The attached patch implements this

According to the clang developers this is a invalid inline assembly.
Using the attached patch from the last commit in the below bug report fixes the
compile.

With kernel 2.6.31 the struct input_absinfo defined in linux/input.h changed.
A field "__s32 resolution" was added at the end of the struct.
Because the macro EVIOCGABS(abs) is using the struct input_absinfo, it would be
better (IMHO) to change the declaration of variable values to
"int values[sizeof(struct input_absinfo) / sizeof(int)];" or using "struct
input_absinfo" directly.

I came across further issues with SDL 1.2.14 on win32 in combination
with touch screens.
When you touched the screen older SDLs reported
SDL_MOUSEMOTION to the touch position
SDL_MOUSEBUTTONDOWN at the touch position
1.2.14 reports
SDL_MOUSEBUTTONDOWN at the last mouse position before the touch
and then a
SDL_MOUSEMOTION to the touch position
I found that to fix it in the file SDL_sysevents.c i had to put back the
following lines from 1.2.12 to get it working correctly again:
if ( mouse_relative ) {
/* RJR: March 28, 2000
report internal mouse position if in relative mode */
x = 0; y = 0;
} else {
x = (Sint16)LOWORD(lParam);
y = (Sint16)HIWORD(lParam);
#ifdef _WIN32_WCE
if (SDL_VideoSurface)
GapiTransform(this->hidden->userOrientation,
this->hidden->hiresFix, &x, &y);
#endif
}
posted = SDL_PrivateMouseButton(
state, button, x, y);
where there was only
posted = SDL_PrivateMouseButton(
state, button, 0, 0);
in 1.2.14 (appx. line 484)
please feel free to put that change into any SDL lib you like in any way
you like and thanks for your great work !
