Library-specific foo-config scripts duplicate very similar logic across
various different projects, and tend to break cross-compiling, multilib
(gcc -m32), Debian/Ubuntu multiarch and so on by only being able to have
one sdl2-config at a time as the first one in the PATH.
The direct replacement is pkg-config(1) or a compatible reimplementation
like pkgconf(1), which relies on each library installing declarative
metadata, like SDL's sdl2.pc (available since at least 2.0.0) and
centralizes the logic into the pkg-config/pkgconf tool.
Most uses of `sdl2-config --foo` can be replaced by something similar
to `${PKG_CONFIG:-pkg-config} --foo sdl2`. Instead of adding a custom
sdl2-config to the PATH or using its --prefix or --exec-prefix options,
users of a custom installation prefix can use any of pkg-config's
non-SDL-specific ways to influence the result, for example setting
PKG_CONFIG_PATH, PKG_CONFIG_SYSROOT_DIR or PKG_CONFIG_LIBDIR environment
variables, or setting the PKG_CONFIG environment variable to point to
a wrapper script.
For Autotools specifically, the replacement for AM_PATH_SDL2 (which
will be officially deprecated in a subsequent commit) is
PKG_CHECK_MODULES.
CMake has its own semi-declarative mechanism for dependency discovery,
"config packages", and the SDL build already installs a config
package. There's a good example of using a config package to discover
SDL in `cmake/test/`.
Meson natively supports pkg-config, and already uses it in preference
to sdl2-config.
Other build systems can run pkg-config instead of sdl2-config,
preferably checking the PKG_CONFIG environment variable first.
https://github.com/ioquake/ioq3 is a good example of a project doing
this correctly.

This is a functional state for some window managers (tested using stock Ubuntu 22.04.1), and removing that state, e.g. using SDL_RestoreWindow(), results in a window centered and floating, and not visually covering the rest of the desktop.
This uses a newer browser API to get physical scancodes, but still
uses the (deprecated) event field that we were already using for
scancodes, but for keycodes instead now, which appears to be more
accurate.
Since keyboard layout isn't (generally) available to web apps, this
adds an internal interface to send key events with both scancode
and keycode to SDL's internals, instead of sending just scancodes and
expecting SDL to use its own keymap to generate keycodes.
Future work in this area would be to use the keyboard layout APIs
on browsers that support them, which would allow us to use SDL's
usual keymap code and not rely on a deprecated browser API, but
until we get there, this patch gives significantly more correct
results than we would have before.
Fixes#2098.
Exit the fullscreen sequence sooner if it is requested that a popup window be fullscreen.
The surface commit formerly in this path is irrelevant and can be removed as previous changes made it so that SetFullscreen() is no longer called from anywhere except Wayland_SetWindowFullscreen().
The controller can use either hat or buttons for the D-Pad, depending on what Linux driver is in use. The automatic mapping in LINUX_JoystickGetGamepadMapping() will do the right thing based on the exposed capability bits.
I'm sure this is the case for other controllers as well, so we might be removing more mappings over time.
This ignores 2.x.1 (etc) releases, which prevents it from thinking
the next official non-point-release version is 2.26.1, when it
should be 2.26.0, because it saw the "latest" release is 2.24.1.
This fixes the wiki ending up with imaginary version numbers for
the "this function is available since SDL 2.x.y" sections.
Fixes#6343.
Clear the window to black on the initial window draw, to avoid a really
obnoxious white flash. This doesn't always eliminate it, but it
definitely minimizes it.
This makes the colorspace match across different graphics APIs. By
default, OpenGL was getting a much more saturated colorspace (maybe
Display P3?) and it was looking very different from the rendering done
by Metal or MoltenVK.
