Since #5602, SDL is intended to have the same ABI across the whole
major-version 2 cycle, so we should not check that the minor version
matches the one that was used to compile an application.
There are two checks that could make sense here.
The first check is that the major version matches the expected major
version. This is usually unnecessary and is not usually done (if we're
calling into the wrong library we'll likely crash anyway), but since we
have the information, we might as well continue to use it.
The second check is whether the version provided by the caller is
equal to or greater than a threshold version at which additional fields
were added to the struct. If it is, we should populate those fields;
if it is not, then we cannot. This is only useful on platforms where
additional fields have genuinely been added during the lifetime of
SDL 2, like Windows and DirectFB (but not X11).
This commit changes the first check to be consistent about only looking
at the minor version, while leaving the second check using SDL_VERSIONNUM
(which will be removed or widened in SDL 3, but it's fine for now).

Otherwise we ignore the Configure/etc events when they come in because
the window is already in an identical state as far as SDL is concerned.

Button4 and Button5 are for the scrollwheel, not the extended buttons.
I don't know of a way to query the state of the extended buttons using X11.
These try to pull from the .pdf files that are installed with
macOS, which fit our needs better, and fall back to the most
reasonable defaults available from NSCursor if we can't load
them.
Since these are installed under /System, they should be sandbox
accessible, and if this totally fails, it should still go on,
albeit with a less good cursor.
Reference Issue #2123.
On Gnome (and hopefully others!), this produces something that actually
matches SDL_SYSTEM_CURSOR_SIZENWSE/SDL_SYSTEM_CURSOR_SIZENESW. On
other desktop enviroments, it probably fits the spirit better than
XC_fleur in any case.

Added the ability to specify a name and the product VID/PID for a virtual controller
Also added a test case to testgamecontroller, if you pass --virtual as a parameter
Don't be fooled by the diff size - this ended up being a big refactor of the
shell surface management, masked only by some helper macros I wrote for the
popup support.
This change makes it so when xdg_decoration is supported, but CSD is requested,
the system bails on xdg support entirely and resets all the windows to use
libdecor instead. This transition isn't pretty, but once it's done it will be
smooth if decorations are an OS toggle since libdecor will take things from
there.
In hindsight, we really should have designed libdecor to be passed a toplevel,
having it manage that for us keeps causing major refactors for _every_ change.
Move rendering of the assert message into a separate
function so we can remove the ugly loop construction.
Changes the logic such that allocation failure no longer
immediately returns SDL_ASSERTION_ABORT, instead we
fall back to the truncated message.
If an error is indicated from SDL_snprintf, then we do
abort with SDL_ASSERTION_ABORT.
* Add changes from code review by @ccawley2011, #5597, overall cleanup
* Update N-Gage README, minor cleanup and rephrasing
* Call SDL_SetMainReady() before calling SDL_main, return SDL_main instead of main
Change Cocoa SDL_VideoData and SDL_WindowData implementations from C structs to Objective-C objects, since bridging between C and ObjC is easier that way.
If the size to be allocated is very large and untrusted, then adding
the padding etc. might be enough to cause unsigned overflow, after
which a very small amount of memory will be allocated.

If we're strict about applying something resembling semantic versioning
to the "marketing" version number, then we can mechanically generate
the ABI version from it.
This limits the range of valid micro versions (patchlevels) to 0-99.

For stable releases, this gives us the ability to make bugfix-only point
releases such as 2.24.1 if we want to, and distinguish between them
programmatically. For example, this ability could have been useful after
2.0.16 to fix Xwayland regressions, and after 2.0.18 to fix event loop
regressions.
For development releases, this gives us the ability to make multiple
prereleases during the same feature cycle, and distinguish between them
programmatically. For example, this would have been useful during 2.0.22
development, which went through three prereleases before reaching the
final release.

Enabling GCController.shouldMonitorBackgroundEvents to read background events
for MFi controllers before receiving the first GCControllerDidConnectNotification
is apparently a no-go on macOS (12.3.1 for me), and would crash on attempt.
Apple's documentation is... not great, and doesn't point this out.
This waits for IOS_AddMFIJoystickDevice() to get called down the chain from GCControllerDidConnectNotification, and enables GCController.shouldMonitorBackgroundEvents
if it hadn't been already.
On iOS and tvOS, GCController.shouldMonitorBackgroundEvents is ignored, so
there's no need to check their versions.
Ensure that we're not trying to call SDL_small_alloc()
with a count of zero.
Transforming the code like this fixes a
-Wmaybe-uninitialized warning from GCC 12.0.1
For short messages, use a stack buffer that is
significantly smaller than SDL_MAX_LOG_MESSAGE.
The rationale for this is that we don't want to risk
blowing the stack, while at the same time we would
like to not put pressure on the memory allocator unless
absolutely necessary.
This is the one that splits the "left wing" into two for loops to
bubble out the conditional that decides if it should read from the
left padding or the input buffer.
I still believe the optimization is good, but the basic logic of it
was incorrect, and needs to be reexamined and fixed before going
back into revision control.
We can get _some_ of the info we need out of standard Xlib and report a
single display (which might actually be multiple physical displays mushed
into a single desktop). This is better than nothing, but you should really
just build with XRandR support and get a better X server. :)
- Calculate `j * RESAMPLER_SAMPLES_PER_ZERO_CROSSING` once per loop
iteration since we use it multiple times.
- Do the left-wing loop in two sections: while `srcframe < 0` and then
the remaining calculations when `srcframe >= 0`. This bubbles a conditional
out of every iteration of a tight loop, giving us a boost. We could
_probably_ do this to the right-wing loop too, but it's less straightforward
there.
- The real win: Use floats instead of doubles. This almost doubles the speed
of the entire function on Intel CPUs, and for embedded things without
hardware-level support for doubles, the speedup is enormous. This in
theory might reduce audio quality, though, and I had to put a check in
place to avoid a division-by-zero that we avoided at higher precision, but
this is likely to be worth keeping for at least the Sony PSP and other
smaller platforms, if not everyone.
Instead of waiting until the entire buffer from the SDL callback is ready
to be accepted by PulseAudio, we use pa_stream_set_write_callback and
feed some portion of the buffer as callbacks come in asking for more.
This lets us remove the halving of the buffer size during device open,
and also (hopefully) solves several strange hangs that happen in unusual
circumstances.

* Read IMU scale data from Switch controllers. Up until now, SDL has used hard-coded scaling which isn't correct with some supported controllers.
* Moved declarations to beginning of code blocks to better fit with SDL style requirements
Every other backend does this, so this should match, now.
It's possible this was harmless, but we can avoid the system call
and the (likely?) debug message when it fails, though!
When mode switching is disabled in a video backend, fullscreen windows are basically just fullscreen desktop windows with different internal scaling. As no mode switching occurs, there's no need to minimize them on focus loss by default. This can still be overridden by explicitly setting the internal hint for minimizing on focus loss.
This has the side effect of fixing a bug on GNOME, where, when a fullscreen Wayland window has it's focus lost and restored via alt+tab followed by switching back to windowed mode, the top portion of the window won't end up being obstructed by GNOME's top bar.
This reverts commit 8ceba27d62.
SDL Wayland support is stable, but there are a number of issues with third-party software (NVIDIA drivers, libwayland event overflow, libdecor not handling plugin load failures, Steam overlay not working with Wayland, etc.) that make it better to default to X11 at this time.
Games which would like to prefer wayland when available can use the following code before SDL_Init():
SDL_SetHint(SDL_HINT_VIDEODRIVER, "wayland,x11");
Fixes https://github.com/libsdl-org/SDL/issues/5527
This hint allows libdecor to be used even when xdg-decoration is
available. It's mostly useful for debugging libdecor, but could in
theory be used by applications which want to (for example) bundle their
own libdecor plugins.
When using emulated display modes, the output size is often larger than the drawable buffer. As the surface damage region is automatically calculated from the smaller drawable buffer size, the damage region needs to be manually set to cover the entire viewport region or visual repaint artifacts can result.
I kind of thought it'd be nice to have it in the center, but this is an issue
for applications that still assume global mouse and window positions are
accessible. For example, this fixes cursor offset issues in UE5.
It's possible that an external component (probably a GL/VK context) committed, so we need to cover our bases and detach in both HideWindow and ShowWindow.
Fixes a crash in UE5 editor's pop-ups.
Partially fixes the mouse cursor in UE5 editor. Imperfect because UE5 uses window position and global mouse state to get position, but of course we don't have global mouse and this is just to get the right display index so this still fails overall. We really need to make global mouse support a feature query...
So if Gnome/KDE/etc have a keyboard shortcut or titlebar decoration to
make any window go fullscreen (with the _NET_WM_FULLSCREEN flag on the
_NET_WM_STATE property), we update the SDL window flag.
Fixes#5390.
This makes sure the window doesn't have outdated values if you try to access
them (or call something that does, like SDL_SetWindowMinimumSize).
Fixes#5233.
On Wine, when a window is programmatically minimized in response
to losing focus, we receive a WM_ACTIVATE for the deactivation,
but GetForegroundWindow still indicates that our window is focused.
This causes an incorrect SDL_WINDOWEVENT_FOCUS_GAINED.
This is probably a Wine bug, but it may take a while to fix and
then for the fix to make its way to users.
libGL.so may register callbacks that can be invoked upon XCloseDisplay().
If XCloseDisplay() is called after libGL.so is unloaded, the callback pointer
will point at freed memory and invoking it will crash.
The texture framebuffer check optimized out in f37e4a9 was causing libGL.so to
never be unloaded as a side-effect. Skipping it exposed this bug by allowing
libGL.so to actually unload.
