+/**
+ * # CategoryAssert
+ *
+ * A helpful assertion macro!
+ *
+ * SDL assertions operate like your usual `assert` macro, but with some added
+ * features:
+ *
+ * - It uses a trick with the `sizeof` operator, so disabled assertions
+ *   vaporize out of the compiled code, but variables only referenced in the
+ *   assertion won't trigger compiler warnings about being unused.
+ * - It is safe to use with a dangling-else: `if (x) SDL_assert(y); else
+ *   do_something();`
+ * - It works the same everywhere, instead of counting on various platforms'
+ *   compiler and C runtime to behave.
+ * - It provides multiple levels of assertion (SDL_assert, SDL_assert_release,
+ *   SDL_assert_paranoid) instead of a single all-or-nothing option.
+ * - It offers a variety of responses when an assertion fails (retry, trigger
+ *   the debugger, abort the program, ignore the failure once, ignore it for
+ *   the rest of the program's run).
+ * - It tries to show the user a dialog by default, if possible, but the app
+ *   can provide a callback to handle assertion failures however they like.
+ * - It lets failed assertions be retried. Perhaps you had a network failure
+ *   and just want to retry the test after plugging your network cable back
+ *   in? You can.
+ * - It lets the user ignore an assertion failure, if there's a harmless
+ *   problem that one can continue past.
+ * - It lets the user mark an assertion as ignored for the rest of the
+ *   program's run; if there's a harmless problem that keeps popping up.
+ * - It provides statistics and data on all failed assertions to the app.
+ * - It allows the default assertion handler to be controlled with environment
+ *   variables, in case an automated script needs to control it.
+ * - It can be used as an aid to Clang's static analysis; it will treat SDL
+ *   assertions as universally true (under the assumption that you are serious
+ *   about the asserted claims and that your debug builds will detect when
+ *   these claims were wrong). This can help the analyzer avoid false
+ *   positives.
+ *
+ * To use it: compile a debug build and just sprinkle around tests to check
+ * your code!

+
+/**
+ * # CategoryAsyncIO
+ *
+ * SDL offers a way to perform I/O asynchronously. This allows an app to read
+ * or write files without waiting for data to actually transfer; the functions
+ * that request I/O never block while the request is fulfilled.
+ *
+ * Instead, the data moves in the background and the app can check for results
+ * at their leisure.
+ *
+ * This is more complicated than just reading and writing files in a
+ * synchronous way, but it can allow for more efficiency, and never having
+ * framerate drops as the hard drive catches up, etc.
+ *
+ * The general usage pattern for async I/O is:
+ *
+ * - Create one or more SDL_AsyncIOQueue objects.
+ * - Open files with SDL_AsyncIOFromFile.
+ * - Start I/O tasks to the files with SDL_ReadAsyncIO or SDL_WriteAsyncIO,
+ *   putting those tasks into one of the queues.
+ * - Later on, use SDL_GetAsyncIOResult on a queue to see if any task is
+ *   finished without blocking. Tasks might finish in any order with success
+ *   or failure.
+ * - When all your tasks are done, close the file with SDL_CloseAsyncIO. This
+ *   also generates a task, since it might flush data to disk!
+ *
+ * This all works, without blocking, in a single thread, but one can also wait
+ * on a queue in a background thread, sleeping until new results have arrived:
+ *
+ * - Call SDL_WaitAsyncIOResult from one or more threads to efficiently block
+ *   until new tasks complete.
+ * - When shutting down, call SDL_SignalAsyncIOQueue to unblock any sleeping
+ *   threads despite there being no new tasks completed.
+ *
+ * And, of course, to match the synchronous SDL_LoadFile, we offer
+ * SDL_LoadFileAsync as a convenience function. This will handle allocating a
+ * buffer, slurping in the file data, and null-terminating it; you still check
+ * for results later.
+ *
+ * Behind the scenes, SDL will use newer, efficient APIs on platforms that
+ * support them: Linux's io_uring and Windows 11's IoRing, for example. If
+ * those technologies aren't available, SDL will offload the work to a thread
+ * pool that will manage otherwise-synchronous loads without blocking the app.
+ *
+ * ## Best Practices
+ *
+ * Simple non-blocking I/O--for an app that just wants to pick up data
+ * whenever it's ready without losing framerate waiting on disks to spin--can
+ * use whatever pattern works well for the program. In this case, simply call
+ * SDL_ReadAsyncIO, or maybe SDL_LoadFileAsync, as needed. Once a frame, call
+ * SDL_GetAsyncIOResult to check for any completed tasks and deal with the
+ * data as it arrives.
+ *
+ * If two separate pieces of the same program need their own I/O, it is legal
+ * for each to create their own queue. This will prevent either piece from
+ * accidentally consuming the other's completed tasks. Each queue does require
+ * some amount of resources, but it is not an overwhelming cost. Do not make a
+ * queue for each task, however. It is better to put many tasks into a single
+ * queue. They will be reported in order of completion, not in the order they
+ * were submitted, so it doesn't generally matter what order tasks are
+ * started.
+ *
+ * One async I/O queue can be shared by multiple threads, or one thread can
+ * have more than one queue, but the most efficient way--if ruthless
+ * efficiency is the goal--is to have one queue per thread, with multiple
+ * threads working in parallel, and attempt to keep each queue loaded with
+ * tasks that are both started by and consumed by the same thread. On modern
+ * platforms that can use newer interfaces, this can keep data flowing as
+ * efficiently as possible all the way from storage hardware to the app, with
+ * no contention between threads for access to the same queue.
+ *
+ * Written data is not guaranteed to make it to physical media by the time a
+ * closing task is completed, unless SDL_CloseAsyncIO is called with its
+ * `flush` parameter set to true, which is to say that a successful result
+ * here can still result in lost data during an unfortunately-timed power
+ * outage if not flushed. However, flushing will take longer and may be
+ * unnecessary, depending on the app's needs.

+ * # CategoryAudio
+ *
+ * Audio functionality for the SDL library.
+ *
+ * All audio in SDL3 revolves around SDL_AudioStream. Whether you want to play
+ * or record audio, convert it, stream it, buffer it, or mix it, you're going
+ * to be passing it through an audio stream.
+ *
+ * Audio streams are quite flexible; they can accept any amount of data at a
+ * time, in any supported format, and output it as needed in any other format,
+ * even if the data format changes on either side halfway through.
+ *
+ * An app opens an audio device and binds any number of audio streams to it,
+ * feeding more data to the streams as available. When the device needs more
+ * data, it will pull it from all bound streams and mix them together for
+ * playback.
+ *
+ * Audio streams can also use an app-provided callback to supply data
+ * on-demand, which maps pretty closely to the SDL2 audio model.
+ *
+ * SDL also provides a simple .WAV loader in SDL_LoadWAV (and SDL_LoadWAV_IO
+ * if you aren't reading from a file) as a basic means to load sound data into
+ * your program.
+ *
+ * ## Logical audio devices
+ *
+ * In SDL3, opening a physical device (like a SoundBlaster 16 Pro) gives you a
+ * logical device ID that you can bind audio streams to. In almost all cases,
+ * logical devices can be used anywhere in the API that a physical device is
+ * normally used. However, since each device opening generates a new logical
+ * device, different parts of the program (say, a VoIP library, or
+ * text-to-speech framework, or maybe some other sort of mixer on top of SDL)
+ * can have their own device opens that do not interfere with each other; each
+ * logical device will mix its separate audio down to a single buffer, fed to
+ * the physical device, behind the scenes. As many logical devices as you like
+ * can come and go; SDL will only have to open the physical device at the OS
+ * level once, and will manage all the logical devices on top of it
+ * internally.
+ *
+ * One other benefit of logical devices: if you don't open a specific physical
+ * device, instead opting for the default, SDL can automatically migrate those
+ * logical devices to different hardware as circumstances change: a user
+ * plugged in headphones? The system default changed? SDL can transparently
+ * migrate the logical devices to the correct physical device seamlessly and
+ * keep playing; the app doesn't even have to know it happened if it doesn't
+ * want to.
+ *
+ * ## Simplified audio
+ *
+ * As a simplified model for when a single source of audio is all that's
+ * needed, an app can use SDL_OpenAudioDeviceStream, which is a single
+ * function to open an audio device, create an audio stream, bind that stream
+ * to the newly-opened device, and (optionally) provide a callback for
+ * obtaining audio data. When using this function, the primary interface is
+ * the SDL_AudioStream and the device handle is mostly hidden away; destroying
+ * a stream created through this function will also close the device, stream
+ * bindings cannot be changed, etc. One other quirk of this is that the device
+ * is started in a _paused_ state and must be explicitly resumed; this is
+ * partially to offer a clean migration for SDL2 apps and partially because
+ * the app might have to do more setup before playback begins; in the
+ * non-simplified form, nothing will play until a stream is bound to a device,
+ * so they start _unpaused_.
+ *
+ * ## Channel layouts
+ *
+ * Audio data passing through SDL is uncompressed PCM data, interleaved. One
+ * can provide their own decompression through an MP3, etc, decoder, but SDL
+ * does not provide this directly. Each interleaved channel of data is meant
+ * to be in a specific order.
+ *
+ * Abbreviations:
+ *
+ * - FRONT = single mono speaker
+ * - FL = front left speaker
+ * - FR = front right speaker
+ * - FC = front center speaker
+ * - BL = back left speaker
+ * - BR = back right speaker
+ * - SR = surround right speaker
+ * - SL = surround left speaker
+ * - BC = back center speaker
+ * - LFE = low-frequency speaker
+ *
+ * These are listed in the order they are laid out in memory, so "FL, FR"
+ * means "the front left speaker is laid out in memory first, then the front
+ * right, then it repeats for the next audio frame".
+ *
+ * - 1 channel (mono) layout: FRONT
+ * - 2 channels (stereo) layout: FL, FR
+ * - 3 channels (2.1) layout: FL, FR, LFE
+ * - 4 channels (quad) layout: FL, FR, BL, BR
+ * - 5 channels (4.1) layout: FL, FR, LFE, BL, BR
+ * - 6 channels (5.1) layout: FL, FR, FC, LFE, BL, BR (last two can also be
+ *   SL, SR)
+ * - 7 channels (6.1) layout: FL, FR, FC, LFE, BC, SL, SR
+ * - 8 channels (7.1) layout: FL, FR, FC, LFE, BL, BR, SL, SR
+ *
+ * This is the same order as DirectSound expects, but applied to all
+ * platforms; SDL will swizzle the channels as necessary if a platform expects
+ * something different.
+ *
+ * SDL_AudioStream can also be provided channel maps to change this ordering
+ * to whatever is necessary, in other audio processing scenarios.

+ * with a copy of any incoming data.
+ *
+ * An opened audio device starts out with no audio streams bound. To start

+ * there is no audio callback; you only bind audio streams and make sure they
+ * have data flowing into them (however, you can simulate SDL2's semantics
+ * fairly closely by using SDL_OpenAudioDeviceStream instead of this
+ * function).
+ *
+ * If you don't care about opening a specific device, pass a `devid` of either
+ * `SDL_AUDIO_DEVICE_DEFAULT_PLAYBACK` or
+ * `SDL_AUDIO_DEVICE_DEFAULT_RECORDING`. In this case, SDL will try to pick

+ * preferences, the default got unplugged so the system jumped to a new
+ * default, the user plugged in headphones on a mobile device, etc). Unless
+ * you have a good reason to choose a specific device, this is probably what

+ * You may request a specific format for the audio device, but there is no
+ * promise the device will honor that request for several reasons. As such,
+ * it's only meant to be a hint as to what data your app will provide. Audio
+ * streams will accept data in whatever format you specify and manage
+ * conversion for you as appropriate. SDL_GetAudioDeviceFormat can tell you
+ * the preferred format for the device before opening and the actual format
+ * the device is using after opening.
+ *
+ * It's legal to open the same device ID more than once; each successful open
+ * will generate a new logical SDL_AudioDeviceID that is managed separately
+ * from others on the same physical device. This allows libraries to open a
+ * device separately from the main app and bind its own streams without
+ * conflicting.

+ * Some backends might offer arbitrary devices (for example, a networked audio
+ * protocol that can connect to an arbitrary server). For these, as a change
+ * from SDL2, you should open a default device ID and use an SDL hint to
+ * specify the target if you care, or otherwise let the backend figure out a
+ * reasonable default. Most backends don't offer anything like this, and often
+ * this would be an end user setting an environment variable for their custom
+ * need, and not something an application should specifically manage.

+ * memory and decoded if necessary.
+ *
+ * Supported formats are RIFF WAVE files with the formats PCM (8, 16, 24, and
+ * 32 bits), IEEE Float (32 bits), Microsoft ADPCM and IMA ADPCM (4 bits), and
+ * A-law and mu-law (8 bits). Other formats are currently unsupported and
+ * cause an error.
+ *
+ * If this function succeeds, the return value is zero and the pointer to the
+ * audio data allocated by the function is written to `audio_buf` and its
+ * length in bytes to `audio_len`. The SDL_AudioSpec members `freq`,

+ * buffer.
+ *
+ * It's necessary to use SDL_free() to free the audio data returned in
+ * `audio_buf` when it is no longer used.
+ *
+ * Because of the underspecification of the .WAV format, there are many
+ * problematic files in the wild that cause issues with strict decoders. To
+ * provide compatibility with these files, this decoder is lenient in regards
+ * to the truncation of the file, the fact chunk, and the size of the RIFF
+ * chunk. The hints `SDL_HINT_WAVE_RIFF_CHUNK_SIZE`,
+ * `SDL_HINT_WAVE_TRUNCATION`, and `SDL_HINT_WAVE_FACT_CHUNK` can be used to
+ * tune the behavior of the loading process.
+ *
+ * Any file that is invalid (due to truncation, corruption, or wrong values in
+ * the headers), too big, or unsupported causes an error. Additionally, any
+ * critical I/O error from the data source will terminate the loading process
+ * with an error. The function returns NULL on error and in all cases (with

+ * Compose a custom blend mode for renderers.
+ *
+ * The functions SDL_SetRenderDrawBlendMode and SDL_SetTextureBlendMode accept
+ * the SDL_BlendMode returned by this function if the renderer supports it.
+ *
+ * A blend mode controls how the pixels from a drawing operation (source) get
+ * combined with the pixels from the render target (destination). First, the
+ * components of the source and destination pixels get multiplied with their
+ * blend factors. Then, the blend operation takes the two products and
+ * calculates the result that will get stored in the render target.
+ *
+ * Expressed in pseudocode, it would look like this:
+ *
+ * ```c
+ * dstRGB = colorOperation(srcRGB * srcColorFactor, dstRGB * dstColorFactor);
+ * dstA = alphaOperation(srcA * srcAlphaFactor, dstA * dstAlphaFactor);
+ * ```
+ *
+ * Where the functions `colorOperation(src, dst)` and `alphaOperation(src,
+ * dst)` can return one of the following:
+ *
+ * - `src + dst`
+ * - `src - dst`
+ * - `dst - src`
+ * - `min(src, dst)`
+ * - `max(src, dst)`
+ *
+ * The red, green, and blue components are always multiplied with the first,
+ * second, and third components of the SDL_BlendFactor, respectively. The
+ * fourth component is not used.
+ *
+ * The alpha component is always multiplied with the fourth component of the
+ * SDL_BlendFactor. The other components are not used in the alpha
+ * calculation.
+ *
+ * Support for these blend modes varies for each renderer. To check if a
+ * specific SDL_BlendMode is supported, create a renderer and pass it to
+ * either SDL_SetRenderDrawBlendMode or SDL_SetTextureBlendMode. They will
+ * return with an error if the blend mode is not supported.
+ *
+ * This list describes the support of custom blend modes for each renderer.
+ * All renderers support the four blend modes listed in the SDL_BlendMode
+ * enumeration.
+ *
+ * - **direct3d**: Supports all operations with all factors. However, some
+ *   factors produce unexpected results with `SDL_BLENDOPERATION_MINIMUM` and
+ *   `SDL_BLENDOPERATION_MAXIMUM`.
+ * - **direct3d11**: Same as Direct3D 9.
+ * - **opengl**: Supports the `SDL_BLENDOPERATION_ADD` operation with all
+ *   factors. OpenGL versions 1.1, 1.2, and 1.3 do not work correctly here.
+ * - **opengles2**: Supports the `SDL_BLENDOPERATION_ADD`,
+ *   `SDL_BLENDOPERATION_SUBTRACT`, `SDL_BLENDOPERATION_REV_SUBTRACT`
+ *   operations with all factors.
+ * - **psp**: No custom blend mode support.
+ * - **software**: No custom blend mode support.
+ *
+ * Some renderers do not provide an alpha component for the default render
+ * target. The `SDL_BLENDFACTOR_DST_ALPHA` and
+ * `SDL_BLENDFACTOR_ONE_MINUS_DST_ALPHA` factors do not have an effect in this
+ * case.

+/**
+ * # CategoryCamera
+ *
+ * Video capture for the SDL library.
+ *
+ * This API lets apps read input from video sources, like webcams. Camera
+ * devices can be enumerated, queried, and opened. Once opened, it will
+ * provide SDL_Surface objects as new frames of video come in. These surfaces
+ * can be uploaded to an SDL_Texture or processed as pixels in memory.
+ *
+ * Several platforms will alert the user if an app tries to access a camera,
+ * and some will present a UI asking the user if your application should be
+ * allowed to obtain images at all, which they can deny. A successfully opened
+ * camera will not provide images until permission is granted. Applications,
+ * after opening a camera device, can see if they were granted access by
+ * either polling with the SDL_GetCameraPermissionState() function, or waiting
+ * for an SDL_EVENT_CAMERA_DEVICE_APPROVED or SDL_EVENT_CAMERA_DEVICE_DENIED
+ * event. Platforms that don't have any user approval process will report
+ * approval immediately.
+ *
+ * Note that SDL cameras only provide video as individual frames; they will
+ * not provide full-motion video encoded in a movie file format, although an
+ * app is free to encode the acquired frames into any format it likes. It also
+ * does not provide audio from the camera hardware through this API; not only
+ * do many webcams not have microphones at all, many people--from streamers to
+ * people on Zoom calls--will want to use a separate microphone regardless of
+ * the camera. In any case, recorded audio will be available through SDL's
+ * audio API no matter what hardware provides the microphone.
+ *
+ * ## Camera gotchas
+ *
+ * Consumer-level camera hardware tends to take a little while to warm up,
+ * once the device has been opened. Generally most camera apps have some sort
+ * of UI to take a picture (a button to snap a pic while a preview is showing,
+ * some sort of multi-second countdown for the user to pose, like a photo
+ * booth), which puts control in the users' hands, or they are intended to
+ * stay on for long times (Pokemon Go, etc).
+ *
+ * It's not uncommon that a newly-opened camera will provide a couple of
+ * completely black frames, maybe followed by some under-exposed images. If
+ * taking a single frame automatically, or recording video from a camera's
+ * input without the user initiating it from a preview, it could be wise to
+ * drop the first several frames (if not the first several _seconds_ worth of
+ * frames!) before using images from a camera.

+/**
+ * # CategoryClipboard
+ *
+ * SDL provides access to the system clipboard, both for reading information
+ * from other processes and publishing information of its own.
+ *
+ * This is not just text! SDL apps can access and publish data by mimetype.
+ *
+ * ## Basic use (text)
+ *
+ * Obtaining and publishing simple text to the system clipboard is as easy as
+ * calling SDL_GetClipboardText() and SDL_SetClipboardText(), respectively.
+ * These deal with C strings in UTF-8 encoding. Data transmission and encoding
+ * conversion is completely managed by SDL.
+ *
+ * ## Clipboard callbacks (data other than text)
+ *
+ * Things get more complicated when the clipboard contains something other
+ * than text. Not only can the system clipboard contain data of any type, in
+ * some cases it can contain the same data in different formats! For example,
+ * an image painting app might let the user copy a graphic to the clipboard,
+ * and offers it in .BMP, .JPG, or .PNG format for other apps to consume.
+ *
+ * Obtaining clipboard data ("pasting") like this is a matter of calling
+ * SDL_GetClipboardData() and telling it the mimetype of the data you want.
+ * But how does one know if that format is available? SDL_HasClipboardData()
+ * can report if a specific mimetype is offered, and
+ * SDL_GetClipboardMimeTypes() can provide the entire list of mimetypes
+ * available, so the app can decide what to do with the data and what formats
+ * it can support.
+ *
+ * Setting the clipboard ("copying") to arbitrary data is done with
+ * SDL_SetClipboardData. The app does not provide the data in this call, but
+ * rather the mimetypes it is willing to provide and a callback function.
+ * During the callback, the app will generate the data. This allows massive
+ * data sets to be provided to the clipboard, without any data being copied
+ * before it is explicitly requested. More specifically, it allows an app to
+ * offer data in multiple formats without providing a copy of all of them
+ * upfront. If the app has an image that it could provide in PNG or JPG
+ * format, it doesn't have to encode it to either of those unless and until
+ * something tries to paste it.
+ *
+ * ## Primary Selection
+ *
+ * The X11 and Wayland video targets have a concept of the "primary selection"
+ * in addition to the usual clipboard. This is generally highlighted (but not
+ * explicitly copied) text from various apps. SDL offers APIs for this through
+ * SDL_GetPrimarySelectionText() and SDL_SetPrimarySelectionText(). SDL offers
+ * these APIs on platforms without this concept, too, but only so far that it
+ * will keep a copy of a string that the app sets for later retrieval; the
+ * operating system will not ever attempt to change the string externally if
+ * it doesn't support a primary selection.

+ * Functions converting endian-specific values to different byte orders.
+ *
+ * These functions either unconditionally swap byte order (SDL_Swap16,
+ * SDL_Swap32, SDL_Swap64, SDL_SwapFloat), or they swap to/from the system's
+ * native byte order (SDL_Swap16LE, SDL_Swap16BE, SDL_Swap32LE, SDL_Swap32BE,
+ * SDL_Swap32LE, SDL_Swap32BE, SDL_SwapFloatLE, SDL_SwapFloatBE). In the
+ * latter case, the functionality is provided by macros that become no-ops if
+ * a swap isn't necessary: on an x86 (littleendian) processor, SDL_Swap32LE
+ * does nothing, but SDL_Swap32BE reverses the bytes of the data. On a PowerPC
+ * processor (bigendian), the macros behavior is reversed.
+ *
+ * The swap routines are inline functions, and attempt to use compiler
+ * intrinsics, inline assembly, and other magic to make byteswapping
+ * efficient.

+ * Simple error message routines for SDL.
+ *
+ * Most apps will interface with these APIs in exactly one function: when
+ * almost any SDL function call reports failure, you can get a human-readable
+ * string of the problem from SDL_GetError().
+ *
+ * These strings are maintained per-thread, and apps are welcome to set their
+ * own errors, which is popular when building libraries on top of SDL for
+ * other apps to consume. These strings are set by calling SDL_SetError().
+ *
+ * A common usage pattern is to have a function that returns true for success
+ * and false for failure, and do this when something fails:
+ *
+ * ```c
+ * if (something_went_wrong) {
+ *    return SDL_SetError("The thing broke in this specific way: %d", errcode);
+ * }
+ * ```
+ *
+ * It's also common to just return `false` in this case if the failing thing
+ * is known to call SDL_SetError(), so errors simply propagate through.

+ * It is possible for multiple errors to occur before calling SDL_GetError().

+ * The message is only applicable when an SDL function has signaled an error.
+ * You must check the return values of SDL function calls to determine when to

+ * check return values for failure cases before you can assume the error
+ * string applies.

+ * Error strings are set per-thread, so an error set in a different thread
+ * will not interfere with the current thread's operation.
+ *
+ * The returned value is a thread-local string which will remain valid until
+ * the current thread's error string is changed. The caller should make a copy
+ * if the value is needed after the next SDL API call.

+/**
+ * # CategoryEvents
+ *
+ * Event queue management.
+ *
+ * It's extremely common--often required--that an app deal with SDL's event
+ * queue. Almost all useful information about interactions with the real world
+ * flow through here: the user interacting with the computer and app, hardware
+ * coming and going, the system changing in some way, etc.
+ *
+ * An app generally takes a moment, perhaps at the start of a new frame, to
+ * examine any events that have occured since the last time and process or
+ * ignore them. This is generally done by calling SDL_PollEvent() in a loop
+ * until it returns false (or, if using the main callbacks, events are
+ * provided one at a time in calls to SDL_AppEvent() before the next call to
+ * SDL_AppIterate(); in this scenario, the app does not call SDL_PollEvent()
+ * at all).
+ *
+ * There is other forms of control, too: SDL_PeepEvents() has more
+ * functionality at the cost of more complexity, and SDL_WaitEvent() can block
+ * the process until something interesting happens, which might be beneficial
+ * for certain types of programs on low-power hardware. One may also call
+ * SDL_AddEventWatch() to set a callback when new events arrive.
+ *
+ * The app is free to generate their own events, too: SDL_PushEvent allows the
+ * app to put events onto the queue for later retrieval; SDL_RegisterEvents
+ * can guarantee that these events have a type that isn't in use by other
+ * parts of the system.

+/**
+ * # CategoryGamepad
+ *
+ * SDL provides a low-level joystick API, which just treats joysticks as an
+ * arbitrary pile of buttons, axes, and hat switches. If you're planning to
+ * write your own control configuration screen, this can give you a lot of
+ * flexibility, but that's a lot of work, and most things that we consider
+ * "joysticks" now are actually console-style gamepads. So SDL provides the
+ * gamepad API on top of the lower-level joystick functionality.
+ *
+ * The difference between a joystick and a gamepad is that a gamepad tells you
+ * _where_ a button or axis is on the device. You don't speak to gamepads in
+ * terms of arbitrary numbers like "button 3" or "axis 2" but in standard
+ * locations: the d-pad, the shoulder buttons, triggers, A/B/X/Y (or
+ * X/O/Square/Triangle, if you will).
+ *
+ * One turns a joystick into a gamepad by providing a magic configuration
+ * string, which tells SDL the details of a specific device: when you see this
+ * specific hardware, if button 2 gets pressed, this is actually D-Pad Up,
+ * etc.
+ *
+ * SDL has many popular controllers configured out of the box, and users can
+ * add their own controller details through an environment variable if it's
+ * otherwise unknown to SDL.
+ *
+ * In order to use these functions, SDL_Init() must have been called with the
+ * SDL_INIT_GAMEPAD flag. This causes SDL to scan the system for gamepads, and
+ * load appropriate drivers.
+ *
+ * If you would like to receive gamepad updates while the application is in
+ * the background, you should set the following hint before calling
+ * SDL_Init(): SDL_HINT_JOYSTICK_ALLOW_BACKGROUND_EVENTS
+ *
+ * Gamepads support various optional features such as rumble, color LEDs,
+ * touchpad, gyro, etc. The support for these features varies depending on the
+ * controller and OS support available. You can check for LED and rumble
+ * capabilities at runtime by calling SDL_GetGamepadProperties() and checking
+ * the various capability properties. You can check for touchpad by calling
+ * SDL_GetNumGamepadTouchpads() and check for gyro and accelerometer by
+ * calling SDL_GamepadHasSensor().
+ *
+ * By default SDL will try to use the most capable driver available, but you
+ * can tune which OS drivers to use with the various joystick hints in
+ * SDL_hints.h.
+ *
+ * Your application should always support gamepad hotplugging. On some
+ * platforms like Xbox, Steam Deck, etc., this is a requirement for
+ * certification. On other platforms, like macOS and Windows when using
+ * Windows.Gaming.Input, controllers may not be available at startup and will
+ * come in at some point after you've started processing events.

+
+/**
+ * # CategoryGPU
+ *
+ * The GPU API offers a cross-platform way for apps to talk to modern graphics
+ * hardware. It offers both 3D graphics and compute support, in the style of
+ * Metal, Vulkan, and Direct3D 12.
+ *
+ * A basic workflow might be something like this:
+ *
+ * The app creates a GPU device with SDL_CreateGPUDevice(), and assigns it to
+ * a window with SDL_ClaimWindowForGPUDevice()--although strictly speaking you
+ * can render offscreen entirely, perhaps for image processing, and not use a
+ * window at all.
+ *
+ * Next, the app prepares static data (things that are created once and used
+ * over and over). For example:
+ *
+ * - Shaders (programs that run on the GPU): use SDL_CreateGPUShader().
+ * - Vertex buffers (arrays of geometry data) and other rendering data: use
+ *   SDL_CreateGPUBuffer() and SDL_UploadToGPUBuffer().
+ * - Textures (images): use SDL_CreateGPUTexture() and
+ *   SDL_UploadToGPUTexture().
+ * - Samplers (how textures should be read from): use SDL_CreateGPUSampler().
+ * - Render pipelines (precalculated rendering state): use
+ *   SDL_CreateGPUGraphicsPipeline()
+ *
+ * To render, the app creates one or more command buffers, with
+ * SDL_AcquireGPUCommandBuffer(). Command buffers collect rendering
+ * instructions that will be submitted to the GPU in batch. Complex scenes can
+ * use multiple command buffers, maybe configured across multiple threads in
+ * parallel, as long as they are submitted in the correct order, but many apps
+ * will just need one command buffer per frame.
+ *
+ * Rendering can happen to a texture (what other APIs call a "render target")
+ * or it can happen to the swapchain texture (which is just a special texture
+ * that represents a window's contents). The app can use
+ * SDL_WaitAndAcquireGPUSwapchainTexture() to render to the window.
+ *
+ * Rendering actually happens in a Render Pass, which is encoded into a
+ * command buffer. One can encode multiple render passes (or alternate between
+ * render and compute passes) in a single command buffer, but many apps might
+ * simply need a single render pass in a single command buffer. Render Passes
+ * can render to up to four color textures and one depth texture
+ * simultaneously. If the set of textures being rendered to needs to change,
+ * the Render Pass must be ended and a new one must be begun.
+ *
+ * The app calls SDL_BeginGPURenderPass(). Then it sets states it needs for
+ * each draw:
+ *
+ * - SDL_BindGPUGraphicsPipeline()
+ * - SDL_SetGPUViewport()
+ * - SDL_BindGPUVertexBuffers()
+ * - SDL_BindGPUVertexSamplers()
+ * - etc
+ *
+ * Then, make the actual draw commands with these states:
+ *
+ * - SDL_DrawGPUPrimitives()
+ * - SDL_DrawGPUPrimitivesIndirect()
+ * - SDL_DrawGPUIndexedPrimitivesIndirect()
+ * - etc
+ *
+ * After all the drawing commands for a pass are complete, the app should call
+ * SDL_EndGPURenderPass(). Once a render pass ends all render-related state is
+ * reset.
+ *
+ * The app can begin new Render Passes and make new draws in the same command
+ * buffer until the entire scene is rendered.
+ *
+ * Once all of the render commands for the scene are complete, the app calls
+ * SDL_SubmitGPUCommandBuffer() to send it to the GPU for processing.
+ *
+ * If the app needs to read back data from texture or buffers, the API has an
+ * efficient way of doing this, provided that the app is willing to tolerate
+ * some latency. When the app uses SDL_DownloadFromGPUTexture() or
+ * SDL_DownloadFromGPUBuffer(), submitting the command buffer with
+ * SDL_SubmitGPUCommandBufferAndAcquireFence() will return a fence handle that
+ * the app can poll or wait on in a thread. Once the fence indicates that the
+ * command buffer is done processing, it is safe to read the downloaded data.
+ * Make sure to call SDL_ReleaseGPUFence() when done with the fence.
+ *
+ * The API also has "compute" support. The app calls SDL_BeginGPUComputePass()
+ * with compute-writeable textures and/or buffers, which can be written to in
+ * a compute shader. Then it sets states it needs for the compute dispatches:
+ *
+ * - SDL_BindGPUComputePipeline()
+ * - SDL_BindGPUComputeStorageBuffers()
+ * - SDL_BindGPUComputeStorageTextures()
+ *
+ * Then, dispatch compute work:
+ *
+ * - SDL_DispatchGPUCompute()
+ *
+ * For advanced users, this opens up powerful GPU-driven workflows.
+ *
+ * Graphics and compute pipelines require the use of shaders, which as
+ * mentioned above are small programs executed on the GPU. Each backend
+ * (Vulkan, Metal, D3D12) requires a different shader format. When the app
+ * creates the GPU device, the app lets the device know which shader formats
+ * the app can provide. It will then select the appropriate backend depending
+ * on the available shader formats and the backends available on the platform.
+ * When creating shaders, the app must provide the correct shader format for
+ * the selected backend. If you would like to learn more about why the API
+ * works this way, there is a detailed
+ * [blog post](https://moonside.games/posts/layers-all-the-way-down/)
+ * explaining this situation.
+ *
+ * It is optimal for apps to pre-compile the shader formats they might use,
+ * but for ease of use SDL provides a separate project,
+ * [SDL_shadercross](https://github.com/libsdl-org/SDL_shadercross)
+ * , for performing runtime shader cross-compilation. It also has a CLI
+ * interface for offline precompilation as well.
+ *
+ * This is an extremely quick overview that leaves out several important
+ * details. Already, though, one can see that GPU programming can be quite
+ * complex! If you just need simple 2D graphics, the
+ * [Render API](https://wiki.libsdl.org/SDL3/CategoryRender)
+ * is much easier to use but still hardware-accelerated. That said, even for
+ * 2D applications the performance benefits and expressiveness of the GPU API
+ * are significant.
+ *
+ * The GPU API targets a feature set with a wide range of hardware support and
+ * ease of portability. It is designed so that the app won't have to branch
+ * itself by querying feature support. If you need cutting-edge features with
+ * limited hardware support, this API is probably not for you.
+ *
+ * Examples demonstrating proper usage of this API can be found
+ * [here](https://github.com/TheSpydog/SDL_gpu_examples)
+ * .
+ *
+ * ## Performance considerations
+ *
+ * Here are some basic tips for maximizing your rendering performance.
+ *
+ * - Beginning a new render pass is relatively expensive. Use as few render
+ *   passes as you can.
+ * - Minimize the amount of state changes. For example, binding a pipeline is
+ *   relatively cheap, but doing it hundreds of times when you don't need to
+ *   will slow the performance significantly.
+ * - Perform your data uploads as early as possible in the frame.
+ * - Don't churn resources. Creating and releasing resources is expensive.
+ *   It's better to create what you need up front and cache it.
+ * - Don't use uniform buffers for large amounts of data (more than a matrix
+ *   or so). Use a storage buffer instead.
+ * - Use cycling correctly. There is a detailed explanation of cycling further
+ *   below.
+ * - Use culling techniques to minimize pixel writes. The less writing the GPU
+ *   has to do the better. Culling can be a very advanced topic but even
+ *   simple culling techniques can boost performance significantly.
+ *
+ * In general try to remember the golden rule of performance: doing things is
+ * more expensive than not doing things. Don't Touch The Driver!
+ *
+ * ## FAQ
+ *
+ * **Question: When are you adding more advanced features, like ray tracing or
+ * mesh shaders?**
+ *
+ * Answer: We don't have immediate plans to add more bleeding-edge features,
+ * but we certainly might in the future, when these features prove worthwhile,
+ * and reasonable to implement across several platforms and underlying APIs.
+ * So while these things are not in the "never" category, they are definitely
+ * not "near future" items either.
+ *
+ * **Question: Why is my shader not working?**
+ *
+ * Answer: A common oversight when using shaders is not properly laying out
+ * the shader resources/registers correctly. The GPU API is very strict with
+ * how it wants resources to be laid out and it's difficult for the API to
+ * automatically validate shaders to see if they have a compatible layout. See
+ * the documentation for SDL_CreateGPUShader() and
+ * SDL_CreateGPUComputePipeline() for information on the expected layout.
+ *
+ * Another common issue is not setting the correct number of samplers,
+ * textures, and buffers in SDL_GPUShaderCreateInfo. If possible use shader
+ * reflection to extract the required information from the shader
+ * automatically instead of manually filling in the struct's values.
+ *
+ * **Question: My application isn't performing very well. Is this the GPU
+ * API's fault?**
+ *
+ * Answer: No. Long answer: The GPU API is a relatively thin layer over the
+ * underlying graphics API. While it's possible that we have done something
+ * inefficiently, it's very unlikely especially if you are relatively
+ * inexperienced with GPU rendering. Please see the performance tips above and
+ * make sure you are following them. Additionally, tools like RenderDoc can be
+ * very helpful for diagnosing incorrect behavior and performance issues.
+ *
+ * ## System Requirements
+ *
+ * **Vulkan:** Supported on Windows, Linux, Nintendo Switch, and certain
+ * Android devices. Requires Vulkan 1.0 with the following extensions and
+ * device features:
+ *
+ * - `VK_KHR_swapchain`
+ * - `VK_KHR_maintenance1`
+ * - `independentBlend`
+ * - `imageCubeArray`
+ * - `depthClamp`
+ * - `shaderClipDistance`
+ * - `drawIndirectFirstInstance`
+ *
+ * **D3D12:** Supported on Windows 10 or newer, Xbox One (GDK), and Xbox
+ * Series X|S (GDK). Requires a GPU that supports DirectX 12 Feature Level
+ * 11_1.
+ *
+ * **Metal:** Supported on macOS 10.14+ and iOS/tvOS 13.0+. Hardware
+ * requirements vary by operating system:
+ *
+ * - macOS requires an Apple Silicon or
+ *   [Intel Mac2 family](https://developer.apple.com/documentation/metal/mtlfeatureset/mtlfeatureset_macos_gpufamily2_v1?language=objc)
+ *   GPU
+ * - iOS/tvOS requires an A9 GPU or newer
+ * - iOS Simulator and tvOS Simulator are unsupported
+ *
+ * ## Uniform Data
+ *
+ * Uniforms are for passing data to shaders. The uniform data will be constant
+ * across all executions of the shader.
+ *
+ * There are 4 available uniform slots per shader stage (where the stages are
+ * vertex, fragment, and compute). Uniform data pushed to a slot on a stage
+ * keeps its value throughout the command buffer until you call the relevant
+ * Push function on that slot again.
+ *
+ * For example, you could write your vertex shaders to read a camera matrix
+ * from uniform binding slot 0, push the camera matrix at the start of the
+ * command buffer, and that data will be used for every subsequent draw call.
+ *
+ * It is valid to push uniform data during a render or compute pass.
+ *
+ * Uniforms are best for pushing small amounts of data. If you are pushing
+ * more than a matrix or two per call you should consider using a storage
+ * buffer instead.
+ *
+ * ## A Note On Cycling
+ *
+ * When using a command buffer, operations do not occur immediately - they
+ * occur some time after the command buffer is submitted.
+ *
+ * When a resource is used in a pending or active command buffer, it is
+ * considered to be "bound". When a resource is no longer used in any pending
+ * or active command buffers, it is considered to be "unbound".
+ *
+ * If data resources are bound, it is unspecified when that data will be
+ * unbound unless you acquire a fence when submitting the command buffer and
+ * wait on it. However, this doesn't mean you need to track resource usage
+ * manually.
+ *
+ * All of the functions and structs that involve writing to a resource have a
+ * "cycle" bool. SDL_GPUTransferBuffer, SDL_GPUBuffer, and SDL_GPUTexture all
+ * effectively function as ring buffers on internal resources. When cycle is
+ * true, if the resource is bound, the cycle rotates to the next unbound
+ * internal resource, or if none are available, a new one is created. This
+ * means you don't have to worry about complex state tracking and
+ * synchronization as long as cycling is correctly employed.
+ *
+ * For example: you can call SDL_MapGPUTransferBuffer(), write texture data,
+ * SDL_UnmapGPUTransferBuffer(), and then SDL_UploadToGPUTexture(). The next
+ * time you write texture data to the transfer buffer, if you set the cycle
+ * param to true, you don't have to worry about overwriting any data that is
+ * not yet uploaded.
+ *
+ * Another example: If you are using a texture in a render pass every frame,
+ * this can cause a data dependency between frames. If you set cycle to true
+ * in the SDL_GPUColorTargetInfo struct, you can prevent this data dependency.
+ *
+ * Cycling will never undefine already bound data. When cycling, all data in
+ * the resource is considered to be undefined for subsequent commands until
+ * that data is written again. You must take care not to read undefined data.
+ *
+ * Note that when cycling a texture, the entire texture will be cycled, even
+ * if only part of the texture is used in the call, so you must consider the
+ * entire texture to contain undefined data after cycling.
+ *
+ * You must also take care not to overwrite a section of data that has been
+ * referenced in a command without cycling first. It is OK to overwrite
+ * unreferenced data in a bound resource without cycling, but overwriting a
+ * section of data that has already been referenced will produce unexpected
+ * results.

+ * Creates a shader to be used when creating a graphics pipeline.

+ * depending on the shader format.
+ *
+ * For SPIR-V shaders, use the following resource sets:
+ *
+ * For vertex shaders:
+ *
+ * - 0: Sampled textures, followed by storage textures, followed by storage
+ *   buffers
+ * - 1: Uniform buffers
+ *
+ * For fragment shaders:
+ *
+ * - 2: Sampled textures, followed by storage textures, followed by storage
+ *   buffers
+ * - 3: Uniform buffers
+ *
+ * For DXBC and DXIL shaders, use the following register order:
+ *
+ * For vertex shaders:
+ *
+ * - (t[n], space0): Sampled textures, followed by storage textures, followed
+ *   by storage buffers
+ * - (s[n], space0): Samplers with indices corresponding to the sampled
+ *   textures
+ * - (b[n], space1): Uniform buffers
+ *
+ * For pixel shaders:
+ *
+ * - (t[n], space2): Sampled textures, followed by storage textures, followed
+ *   by storage buffers
+ * - (s[n], space2): Samplers with indices corresponding to the sampled
+ *   textures
+ * - (b[n], space3): Uniform buffers
+ *
+ * For MSL/metallib, use the following order:
+ *
+ * - [[texture]]: Sampled textures, followed by storage textures
+ * - [[sampler]]: Samplers with indices corresponding to the sampled textures
+ * - [[buffer]]: Uniform buffers, followed by storage buffers. Vertex buffer 0
+ *   is bound at [[buffer(14)]], vertex buffer 1 at [[buffer(15)]], and so on.
+ *   Rather than manually authoring vertex buffer indices, use the
+ *   [[stage_in]] attribute which will automatically use the vertex input
+ *   information from the SDL_GPUGraphicsPipeline.
+ *
+ * Shader semantics other than system-value semantics do not matter in D3D12

+ * # CategoryHaptic
+ *
+ * The SDL haptic subsystem manages haptic (force feedback) devices.
+ *
+ * The basic usage is as follows:
+ *
+ * - Initialize the subsystem (SDL_INIT_HAPTIC).
+ * - Open a haptic device.
+ * - SDL_OpenHaptic() to open from index.
+ * - SDL_OpenHapticFromJoystick() to open from an existing joystick.
+ * - Create an effect (SDL_HapticEffect).
+ * - Upload the effect with SDL_CreateHapticEffect().
+ * - Run the effect with SDL_RunHapticEffect().
+ * - (optional) Free the effect with SDL_DestroyHapticEffect().
+ * - Close the haptic device with SDL_CloseHaptic().
+ *
+ * Simple rumble example:
+ *
+ * ```c
+ *    SDL_Haptic *haptic = NULL;
+ *
+ *    // Open the device
+ *    SDL_HapticID *haptics = SDL_GetHaptics(NULL);
+ *    if (haptics) {
+ *        haptic = SDL_OpenHaptic(haptics[0]);
+ *        SDL_free(haptics);
+ *    }
+ *    if (haptic == NULL)
+ *       return;
+ *
+ *    // Initialize simple rumble
+ *    if (!SDL_InitHapticRumble(haptic))
+ *       return;
+ *
+ *    // Play effect at 50% strength for 2 seconds
+ *    if (!SDL_PlayHapticRumble(haptic, 0.5, 2000))
+ *       return;
+ *    SDL_Delay(2000);
+ *
+ *    // Clean up
+ *    SDL_CloseHaptic(haptic);
+ * ```
+ *
+ * Complete example:
+ *
+ * ```c
+ * bool test_haptic(SDL_Joystick *joystick)
+ * {
+ *    SDL_Haptic *haptic;
+ *    SDL_HapticEffect effect;
+ *    int effect_id;
+ *
+ *    // Open the device
+ *    haptic = SDL_OpenHapticFromJoystick(joystick);
+ *    if (haptic == NULL) return false; // Most likely joystick isn't haptic
+ *
+ *    // See if it can do sine waves
+ *    if ((SDL_GetHapticFeatures(haptic) & SDL_HAPTIC_SINE)==0) {
+ *       SDL_CloseHaptic(haptic); // No sine effect
+ *       return false;
+ *    }
+ *
+ *    // Create the effect
+ *    SDL_memset(&effect, 0, sizeof(SDL_HapticEffect)); // 0 is safe default
+ *    effect.type = SDL_HAPTIC_SINE;
+ *    effect.periodic.direction.type = SDL_HAPTIC_POLAR; // Polar coordinates
+ *    effect.periodic.direction.dir[0] = 18000; // Force comes from south
+ *    effect.periodic.period = 1000; // 1000 ms
+ *    effect.periodic.magnitude = 20000; // 20000/32767 strength
+ *    effect.periodic.length = 5000; // 5 seconds long
+ *    effect.periodic.attack_length = 1000; // Takes 1 second to get max strength
+ *    effect.periodic.fade_length = 1000; // Takes 1 second to fade away
+ *
+ *    // Upload the effect
+ *    effect_id = SDL_CreateHapticEffect(haptic, &effect);
+ *
+ *    // Test the effect
+ *    SDL_RunHapticEffect(haptic, effect_id, 1);
+ *    SDL_Delay(5000); // Wait for the effect to finish
+ *
+ *    // We destroy the effect, although closing the device also does this
+ *    SDL_DestroyHapticEffect(haptic, effect_id);
+ *
+ *    // Close the device
+ *    SDL_CloseHaptic(haptic);
+ *
+ *    return true; // Success
+ * }
+ * ```
+ *
+ * Note that the SDL haptic subsystem is not thread-safe.

+ *
+ * If type is SDL_HAPTIC_POLAR, direction is encoded by hundredths of a degree
+ * starting north and turning clockwise. SDL_HAPTIC_POLAR only uses the first
+ * `dir` parameter. The cardinal directions would be:
+ *
+ * - North: 0 (0 degrees)
+ * - East: 9000 (90 degrees)
+ * - South: 18000 (180 degrees)
+ * - West: 27000 (270 degrees)
+ *
+ * If type is SDL_HAPTIC_CARTESIAN, direction is encoded by three positions (X
+ * axis, Y axis and Z axis (with 3 axes)). SDL_HAPTIC_CARTESIAN uses the first
+ * three `dir` parameters. The cardinal directions would be:
+ *
+ * - North: 0,-1, 0
+ * - East: 1, 0, 0
+ * - South: 0, 1, 0
+ * - West: -1, 0, 0
+ *
+ * The Z axis represents the height of the effect if supported, otherwise it's
+ * unused. In cartesian encoding (1, 2) would be the same as (2, 4), you can
+ * use any multiple you want, only the direction matters.
+ *
+ * If type is SDL_HAPTIC_SPHERICAL, direction is encoded by two rotations. The
+ * first two `dir` parameters are used. The `dir` parameters are as follows
+ * (all values are in hundredths of degrees):
+ *
+ * - Degrees from (1, 0) rotated towards (0, 1).
+ * - Degrees towards (0, 0, 1) (device needs at least 3 axes).
+ *
+ * Example of force coming from the south with all encodings (force coming
+ * from the south means the user will have to pull the stick to counteract):
+ *
+ * ```c
+ *  SDL_HapticDirection direction;
+ *
+ *  // Cartesian directions
+ *  direction.type = SDL_HAPTIC_CARTESIAN; // Using cartesian direction encoding.
+ *  direction.dir[0] = 0; // X position
+ *  direction.dir[1] = 1; // Y position
+ *  // Assuming the device has 2 axes, we don't need to specify third parameter.
+ *
+ *  // Polar directions

+ * # CategoryInit
+ *
+ * All SDL programs need to initialize the library before starting to work
+ * with it.
+ *
+ * Almost everything can simply call SDL_Init() near startup, with a handful
+ * of flags to specify subsystems to touch. These are here to make sure SDL
+ * does not even attempt to touch low-level pieces of the operating system
+ * that you don't intend to use. For example, you might be using SDL for video
+ * and input but chose an external library for audio, and in this case you
+ * would just need to leave off the `SDL_INIT_AUDIO` flag to make sure that
+ * external library has complete control.
+ *
+ * Most apps, when terminating, should call SDL_Quit(). This will clean up
+ * (nearly) everything that SDL might have allocated, and crucially, it'll
+ * make sure that the display's resolution is back to what the user expects if
+ * you had previously changed it for your game.
+ *
+ * SDL3 apps are strongly encouraged to call SDL_SetAppMetadata() at startup
+ * to fill in details about the program. This is completely optional, but it
+ * helps in small ways (we can provide an About dialog box for the macOS menu,
+ * we can name the app in the system's audio mixer, etc). Those that want to
+ * provide a _lot_ of information should look at the more-detailed
+ * SDL_SetAppMetadataProperty().

+ * SDL does some preprocessor gymnastics to determine if any CPU-specific
+ * compiler intrinsics are available, as this is not necessarily an easy thing
+ * to calculate, and sometimes depends on quirks of a system, versions of
+ * build tools, and other external forces.
+ *
+ * Apps including SDL's headers will be able to check consistent preprocessor
+ * definitions to decide if it's safe to use compiler intrinsics for a
+ * specific CPU architecture. This check only tells you that the compiler is
+ * capable of using those intrinsics; at runtime, you should still check if
+ * they are available on the current system with the
+ * [CPU info functions](https://wiki.libsdl.org/SDL3/CategoryCPUInfo)
+ * , such as SDL_HasSSE() or SDL_HasNEON(). Otherwise, the process might crash
+ * for using an unsupported CPU instruction.
+ *
+ * SDL only sets preprocessor defines for CPU intrinsics if they are
+ * supported, so apps should check with `#ifdef` and not `#if`.
+ *
+ * SDL will also include the appropriate instruction-set-specific support
+ * headers, so if SDL decides to define SDL_SSE2_INTRINSICS, it will also
+ * `#include <emmintrin.h>` as well.

+ * A macro to tag a function as targeting a specific CPU architecture.

+ *
+ * The particulars of this are explained in the GCC documentation:
+ *
+ * https://gcc.gnu.org/onlinedocs/gcc/Common-Function-Attributes.html#index-target-function-attribute
+ *
+ * An example of using this feature is to turn on SSE2 support for a specific
+ * function, even if the rest of the source code is not compiled to use SSE2
+ * code:
+ *
+ * ```c
+ * #ifdef SDL_SSE2_INTRINSICS
+ * static void SDL_TARGETING("sse2") DoSomethingWithSSE2(char *x) {
+ *    ...use SSE2 intrinsic functions, etc...

+ * if (SDL_HasSSE2()) {
+ *     DoSomethingWithSSE2(str);
+ * }
+ * #endif
+ * ```
+ *
+ * The application is, on a whole, built without SSE2 instructions, so it will
+ * run on Intel machines that don't support SSE2. But then at runtime, it
+ * checks if the system supports the instructions, and then calls into a
+ * function that uses SSE2 opcodes. The ifdefs make sure that this code isn't
+ * used on platforms that don't have SSE2 at all.
+ *
+ * On compilers without target support, this is defined to nothing.
+ *
+ * This symbol is used by SDL internally, but apps and other libraries are
+ * welcome to use it for their own interfaces as well.

+ * - "a": Append to a file. Writing operations append data at the end of the

+ * - "r+": Open a file for update both reading and writing. The file must
+ *   exist.
+ * - "w+": Create an empty file for both reading and writing. If a file with
+ *   the same name already exists its content is erased and the file is

+ *
+ * **NOTE**: In order to open a file as a binary file, a "b" character has to

+ * be appended at the end of the string (thus making the following compound
+ * modes: "rb", "wb", "ab", "r+b", "w+b", "a+b") or be inserted between the
+ * letter and the "+" sign for the mixed modes ("rb+", "wb+", "ab+").

+ *
+ * SDL joystick support.
+ *
+ * This is the lower-level joystick handling. If you want the simpler option,
+ * where what each button does is well-defined, you should use the gamepad API
+ * instead.
+ *
+ * The term "instance_id" is the current instantiation of a joystick device in
+ * the system, if the joystick is removed and then re-inserted then it will
+ * get a new instance_id, instance_id's are monotonically increasing
+ * identifiers of a joystick plugged in.
+ *
+ * The term "player_index" is the number assigned to a player on a specific
+ * controller. For XInput controllers this returns the XInput user index. Many
+ * joysticks will not be able to supply this information.
+ *
+ * SDL_GUID is used as a stable 128-bit identifier for a joystick device that
+ * does not change over time. It identifies class of the device (a X360 wired
+ * controller for example). This identifier is platform dependent.
+ *
+ * In order to use these functions, SDL_Init() must have been called with the
+ * SDL_INIT_JOYSTICK flag. This causes SDL to scan the system for joysticks,
+ * and load appropriate drivers.
+ *
+ * If you would like to receive joystick updates while the application is in
+ * the background, you should set the following hint before calling
+ * SDL_Init(): SDL_HINT_JOYSTICK_ALLOW_BACKGROUND_EVENTS

+ * - `SDL_PROP_TEXTINPUT_AUTOCORRECT_BOOLEAN` - true to enable auto completion

+/**
+ * # CategorySharedObject
+ *
+ * System-dependent library loading routines.
+ *
+ * Shared objects are code that is programmatically loadable at runtime.
+ * Windows calls these "DLLs", Linux calls them "shared libraries", etc.
+ *
+ * To use them, build such a library, then call SDL_LoadObject() on it. Once
+ * loaded, you can use SDL_LoadFunction() on that object to find the address
+ * of its exported symbols. When done with the object, call SDL_UnloadObject()
+ * to dispose of it.
+ *
+ * Some things to keep in mind:
+ *
+ * - These functions only work on C function names. Other languages may have
+ *   name mangling and intrinsic language support that varies from compiler to
+ *   compiler.
+ * - Make sure you declare your function pointers with the same calling
+ *   convention as the actual library function. Your code will crash
+ *   mysteriously if you do not do this.
+ * - Avoid namespace collisions. If you load a symbol from the library, it is
+ *   not defined whether or not it goes into the global symbol namespace for
+ *   the application. If it does and it conflicts with symbols in your code or
+ *   other shared libraries, you will not get the results you expect. :)
+ * - Once a library is unloaded, all pointers into it obtained through
+ *   SDL_LoadFunction() become invalid, even if the library is later reloaded.
+ *   Don't unload a library if you plan to use these pointers in the future.
+ *   Notably: beware of giving one of these pointers to atexit(), since it may
+ *   call that pointer after the library unloads.

+/**
+ * # CategoryLog
+ *
+ * Simple log messages with priorities and categories. A message's
+ * SDL_LogPriority signifies how important the message is. A message's
+ * SDL_LogCategory signifies from what domain it belongs to. Every category
+ * has a minimum priority specified: when a message belongs to that category,
+ * it will only be sent out if it has that minimum priority or higher.
+ *
+ * SDL's own logs are sent below the default priority threshold, so they are
+ * quiet by default.
+ *
+ * You can change the log verbosity programmatically using
+ * SDL_SetLogPriority() or with SDL_SetHint(SDL_HINT_LOGGING, ...), or with
+ * the "SDL_LOGGING" environment variable. This variable is a comma separated
+ * set of category=level tokens that define the default logging levels for SDL
+ * applications.
+ *
+ * The category can be a numeric category, one of "app", "error", "assert",
+ * "system", "audio", "video", "render", "input", "test", or `*` for any
+ * unspecified category.
+ *
+ * The level can be a numeric level, one of "trace", "verbose", "debug",
+ * "info", "warn", "error", "critical", or "quiet" to disable that category.
+ *
+ * You can omit the category if you want to set the logging level for all
+ * categories.
+ *
+ * If this hint isn't set, the default log levels are equivalent to:
+ *
+ * `app=info,assert=warn,test=verbose,*=error`
+ *
+ * Here's where the messages go on different platforms:
+ *
+ * - Windows: debug output stream
+ * - Android: log output
+ * - Others: standard error output (stderr)
+ *
+ * You don't need to have a newline (`\n`) on the end of messages, the
+ * functions will do that for you. For consistent behavior cross-platform, you
+ * shouldn't have any newlines in messages, such as to log multiple lines in
+ * one call; unusual platform-specific behavior can be observed in such usage.
+ * Do one log call per line instead, with no newlines in messages.
+ *
+ * Each log call is atomic, so you won't see log messages cut off one another
+ * when logging from multiple threads.

+/**
+ * # CategoryMouse
+ *
+ * Any GUI application has to deal with the mouse, and SDL provides functions
+ * to manage mouse input and the displayed cursor.
+ *
+ * Most interactions with the mouse will come through the event subsystem.
+ * Moving a mouse generates an SDL_EVENT_MOUSE_MOTION event, pushing a button
+ * generates SDL_EVENT_MOUSE_BUTTON_DOWN, etc, but one can also query the
+ * current state of the mouse at any time with SDL_GetMouseState().
+ *
+ * For certain games, it's useful to disassociate the mouse cursor from mouse
+ * input. An FPS, for example, would not want the player's motion to stop as
+ * the mouse hits the edge of the window. For these scenarios, use
+ * SDL_SetWindowRelativeMouseMode(), which hides the cursor, grabs mouse input
+ * to the window, and reads mouse input no matter how far it moves.
+ *
+ * Games that want the system to track the mouse but want to draw their own
+ * cursor can use SDL_HideCursor() and SDL_ShowCursor(). It might be more
+ * efficient to let the system manage the cursor, if possible, using
+ * SDL_SetCursor() with a custom image made through SDL_CreateColorCursor(),
+ * or perhaps just a specific system cursor from SDL_CreateSystemCursor().
+ *
+ * SDL can, on many platforms, differentiate between multiple connected mice,
+ * allowing for interesting input scenarios and multiplayer games. They can be
+ * enumerated with SDL_GetMice(), and SDL will send SDL_EVENT_MOUSE_ADDED and
+ * SDL_EVENT_MOUSE_REMOVED events as they are connected and unplugged.
+ *
+ * Since many apps only care about basic mouse input, SDL offers a virtual
+ * mouse device for touch and pen input, which often can make a desktop
+ * application work on a touchscreen phone without any code changes. Apps that
+ * care about touch/pen separately from mouse input should filter out events
+ * with a `which` field of SDL_TOUCH_MOUSEID/SDL_PEN_MOUSEID.

+ *
+ * While captured, mouse events still report coordinates relative to the

+/**
+ * # CategoryPixels
+ *
+ * SDL offers facilities for pixel management.
+ *
+ * Largely these facilities deal with pixel _format_: what does this set of
+ * bits represent?
+ *
+ * If you mostly want to think of a pixel as some combination of red, green,
+ * blue, and maybe alpha intensities, this is all pretty straightforward, and
+ * in many cases, is enough information to build a perfectly fine game.
+ *
+ * However, the actual definition of a pixel is more complex than that:
+ *
+ * Pixels are a representation of a color in a particular color space.
+ *
+ * The first characteristic of a color space is the color type. SDL
+ * understands two different color types, RGB and YCbCr, or in SDL also
+ * referred to as YUV.
+ *
+ * RGB colors consist of red, green, and blue channels of color that are added
+ * together to represent the colors we see on the screen.
+ *
+ * https://en.wikipedia.org/wiki/RGB_color_model
+ *
+ * YCbCr colors represent colors as a Y luma brightness component and red and
+ * blue chroma color offsets. This color representation takes advantage of the
+ * fact that the human eye is more sensitive to brightness than the color in
+ * an image. The Cb and Cr components are often compressed and have lower
+ * resolution than the luma component.
+ *
+ * https://en.wikipedia.org/wiki/YCbCr
+ *
+ * When the color information in YCbCr is compressed, the Y pixels are left at
+ * full resolution and each Cr and Cb pixel represents an average of the color
+ * information in a block of Y pixels. The chroma location determines where in
+ * that block of pixels the color information is coming from.
+ *
+ * The color range defines how much of the pixel to use when converting a
+ * pixel into a color on the display. When the full color range is used, the
+ * entire numeric range of the pixel bits is significant. When narrow color
+ * range is used, for historical reasons, the pixel uses only a portion of the
+ * numeric range to represent colors.
+ *
+ * The color primaries and white point are a definition of the colors in the
+ * color space relative to the standard XYZ color space.
+ *
+ * https://en.wikipedia.org/wiki/CIE_1931_color_space
+ *
+ * The transfer characteristic, or opto-electrical transfer function (OETF),
+ * is the way a color is converted from mathematically linear space into a
+ * non-linear output signals.
+ *
+ * https://en.wikipedia.org/wiki/Rec._709#Transfer_characteristics
+ *
+ * The matrix coefficients are used to convert between YCbCr and RGB colors.

+ * Pixel format.
+ *
+ * SDL's pixel formats have the following naming convention:
+ *
+ * - Names with a list of components and a single bit count, such as RGB24 and
+ *   ABGR32, define a platform-independent encoding into bytes in the order
+ *   specified. For example, in RGB24 data, each pixel is encoded in 3 bytes
+ *   (red, green, blue) in that order, and in ABGR32 data, each pixel is
+ *   encoded in 4 bytes (alpha, blue, green, red) in that order. Use these
+ *   names if the property of a format that is important to you is the order
+ *   of the bytes in memory or on disk.
+ * - Names with a bit count per component, such as ARGB8888 and XRGB1555, are
+ *   "packed" into an appropriately-sized integer in the platform's native
+ *   endianness. For example, ARGB8888 is a sequence of 32-bit integers; in
+ *   each integer, the most significant bits are alpha, and the least
+ *   significant bits are blue. On a little-endian CPU such as x86, the least
+ *   significant bits of each integer are arranged first in memory, but on a
+ *   big-endian CPU such as s390x, the most significant bits are arranged
+ *   first. Use these names if the property of a format that is important to
+ *   you is the meaning of each bit position within a native-endianness
+ *   integer.
+ * - In indexed formats such as INDEX4LSB, each pixel is represented by
+ *   encoding an index into the palette into the indicated number of bits,
+ *   with multiple pixels packed into each byte if appropriate. In LSB
+ *   formats, the first (leftmost) pixel is stored in the least-significant
+ *   bits of the byte; in MSB formats, it's stored in the most-significant
+ *   bits. INDEX8 does not need LSB/MSB variants, because each pixel exactly
+ *   fills one byte.
+ *
+ * The 32-bit byte-array encodings such as RGBA32 are aliases for the
+ * appropriate 8888 encoding for the current platform. For example, RGBA32 is
+ * an alias for ABGR8888 on little-endian CPUs like x86, or an alias for
+ * RGBA8888 on big-endian CPUs.

+ * Get the properties associated with a texture.

+ *
+ * - `SDL_PROP_TEXTURE_COLORSPACE_NUMBER`: an SDL_Colorspace value describing
+ *   the texture colorspace.
+ * - `SDL_PROP_TEXTURE_FORMAT_NUMBER`: one of the enumerated values in
+ *   SDL_PixelFormat.
+ * - `SDL_PROP_TEXTURE_ACCESS_NUMBER`: one of the enumerated values in
+ *   SDL_TextureAccess.
+ * - `SDL_PROP_TEXTURE_WIDTH_NUMBER`: the width of the texture in pixels.
+ * - `SDL_PROP_TEXTURE_HEIGHT_NUMBER`: the height of the texture in pixels.
+ * - `SDL_PROP_TEXTURE_SDR_WHITE_POINT_FLOAT`: for HDR10 and floating point
+ *   textures, this defines the value of 100% diffuse white, with higher
+ *   values being displayed in the High Dynamic Range headroom. This defaults
+ *   to 100 for HDR10 textures and 1.0 for other textures.
+ * - `SDL_PROP_TEXTURE_HDR_HEADROOM_FLOAT`: for HDR10 and floating point
+ *   textures, this defines the maximum dynamic range used by the content, in
+ *   terms of the SDR white point. If this is defined, any values outside the
+ *   range supported by the display will be scaled into the available HDR
+ *   headroom, otherwise they are clipped. This defaults to 1.0 for SDR
+ *   textures, 4.0 for HDR10 textures, and no default for floating point
+ *   textures.
+ *
+ * With the direct3d11 renderer:

+ * starting each new frame's drawing, even if you plan to overwrite every
+ * pixel.
+ *
+ * Please note, that in case of rendering to a texture - there is **no need**
+ * to call `SDL_RenderPresent` after drawing needed objects to a texture, and
+ * should not be done; you are only required to change back the rendering
+ * target to default via `SDL_SetRenderTarget(renderer, NULL)` afterwards, as

+ *
+ * SDL provides its own implementation of some of the most important C runtime
+ * functions.
+ *
+ * Using these functions allows an app to have access to common C
+ * functionality without depending on a specific C runtime (or a C runtime at
+ * all). More importantly, the SDL implementations work identically across
+ * platforms, so apps can avoid surprises like snprintf() behaving differently
+ * between Windows and Linux builds, or itoa() only existing on some
+ * platforms.
+ *
+ * For many of the most common functions, like SDL_memcpy, SDL might just call
+ * through to the usual C runtime behind the scenes, if it makes sense to do
+ * so (if it's faster and always available/reliable on a given platform),
+ * reducing library size and offering the most optimized option.
+ *
+ * SDL also offers other C-runtime-adjacent functionality in this header that
+ * either isn't, strictly speaking, part of any C runtime standards, like
+ * SDL_crc32() and SDL_reinterpret_cast, etc. It also offers a few better
+ * options, like SDL_strlcpy(), which functions as a safer form of strcpy().

+ * # CategoryStorage
+ *
+ * The storage API is a high-level API designed to abstract away the
+ * portability issues that come up when using something lower-level (in SDL's
+ * case, this sits on top of the [Filesystem](CategoryFilesystem) and
+ * [IOStream](CategoryIOStream) subsystems). It is significantly more
+ * restrictive than a typical filesystem API, for a number of reasons:
+ *
+ * 1. **What to Access:** A common pitfall with existing filesystem APIs is
+ * the assumption that all storage is monolithic. However, many other
+ * platforms (game consoles in particular) are more strict about what _type_
+ * of filesystem is being accessed; for example, game content and user data
+ * are usually two separate storage devices with entirely different
+ * characteristics (and possibly different low-level APIs altogether!).
+ *
+ * 2. **How to Access:** Another common mistake is applications assuming that
+ * all storage is universally writeable - again, many platforms treat game
+ * content and user data as two separate storage devices, and only user data
+ * is writeable while game content is read-only.
+ *
+ * 3. **When to Access:** The most common portability issue with filesystem
+ * access is _timing_ - you cannot always assume that the storage device is
+ * always accessible all of the time, nor can you assume that there are no
+ * limits to how long you have access to a particular device.
+ *
+ * Consider the following example:
+ *
+ * ```c
+ * void ReadGameData(void)
+ * {
+ *     extern char** fileNames;
+ *     extern size_t numFiles;
+ *     for (size_t i = 0; i < numFiles; i += 1) {
+ *         FILE *data = fopen(fileNames[i], "rwb");
+ *         if (data == NULL) {
+ *             // Something bad happened!
+ *         } else {
+ *             // A bunch of stuff happens here
+ *             fclose(data);
+ *         }
+ *     }
+ * }
+ *
+ * void ReadSave(void)
+ * {
+ *     FILE *save = fopen("saves/save0.sav", "rb");
+ *     if (save == NULL) {
+ *         // Something bad happened!
+ *     } else {
+ *         // A bunch of stuff happens here
+ *         fclose(save);
+ *     }
+ * }
+ *
+ * void WriteSave(void)
+ * {
+ *     FILE *save = fopen("saves/save0.sav", "wb");
+ *     if (save == NULL) {
+ *         // Something bad happened!
+ *     } else {
+ *         // A bunch of stuff happens here
+ *         fclose(save);
+ *     }
+ * }
+ * ```
+ *
+ * Going over the bullet points again:
+ *
+ * 1. **What to Access:** This code accesses a global filesystem; game data
+ * and saves are all presumed to be in the current working directory (which
+ * may or may not be the game's installation folder!).
+ *
+ * 2. **How to Access:** This code assumes that content paths are writeable,
+ * and that save data is also writeable despite being in the same location as
+ * the game data.
+ *
+ * 3. **When to Access:** This code assumes that they can be called at any
+ * time, since the filesystem is always accessible and has no limits on how
+ * long the filesystem is being accessed.
+ *
+ * Due to these assumptions, the filesystem code is not portable and will fail
+ * under these common scenarios:
+ *
+ * - The game is installed on a device that is read-only, both content loading
+ *   and game saves will fail or crash outright
+ * - Game/User storage is not implicitly mounted, so no files will be found
+ *   for either scenario when a platform requires explicitly mounting
+ *   filesystems
+ * - Save data may not be safe since the I/O is not being flushed or
+ *   validated, so an error occurring elsewhere in the program may result in
+ *   missing/corrupted save data
+ *
+ * When using SDL_Storage, these types of problems are virtually impossible to
+ * trip over:
+ *
+ * ```c
+ * void ReadGameData(void)
+ * {
+ *     extern char** fileNames;
+ *     extern size_t numFiles;
+ *
+ *     SDL_Storage *title = SDL_OpenTitleStorage(NULL, 0);
+ *     if (title == NULL) {
+ *         // Something bad happened!
+ *     }
+ *     while (!SDL_StorageReady(title)) {
+ *         SDL_Delay(1);
+ *     }
+ *
+ *     for (size_t i = 0; i < numFiles; i += 1) {
+ *         void* dst;
+ *         Uint64 dstLen = 0;
+ *
+ *         if (SDL_GetStorageFileSize(title, fileNames[i], &dstLen) && dstLen > 0) {
+ *             dst = SDL_malloc(dstLen);
+ *             if (SDL_ReadStorageFile(title, fileNames[i], dst, dstLen)) {
+ *                 // A bunch of stuff happens here

+ *         }

+ *     }

+ *
+ *     Uint64 saveLen = 0;
+ *     if (SDL_GetStorageFileSize(user, "save0.sav", &saveLen) && saveLen > 0) {
+ *         void* dst = SDL_malloc(saveLen);
+ *         if (SDL_ReadStorageFile(user, "save0.sav", dst, saveLen)) {

+ *         } else {

+ *         }
+ *         SDL_free(dst);
+ *     } else {

+ *     if (user == NULL) {
+ *         // Something bad happened!
+ *     }
+ *     while (!SDL_StorageReady(user)) {
+ *         SDL_Delay(1);
+ *     }
+ *
+ *     extern void *saveData; // A bunch of stuff happened here...

+ *         // Something bad happened!
+ *     }
+ *
+ *     SDL_CloseStorage(user);
+ * }
+ * ```
+ *
+ * Note the improvements that SDL_Storage makes:
+ *
+ * 1. **What to Access:** This code explicitly reads from a title or user
+ * storage device based on the context of the function.
+ *
+ * 2. **How to Access:** This code explicitly uses either a read or write
+ * function based on the context of the function.
+ *
+ * 3. **When to Access:** This code explicitly opens the device when it needs
+ * to, and closes it when it is finished working with the filesystem.
+ *
+ * The result is an application that is significantly more robust against the
+ * increasing demands of platforms and their filesystems!
+ *
+ * A publicly available example of an SDL_Storage backend is the
+ * [Steam Cloud](https://partner.steamgames.com/doc/features/cloud)
+ * backend - you can initialize Steamworks when starting the program, and then
+ * SDL will recognize that Steamworks is initialized and automatically use
+ * ISteamRemoteStorage when the application opens user storage. More
+ * importantly, when you _open_ storage it knows to begin a "batch" of
+ * filesystem operations, and when you _close_ storage it knows to end and
+ * flush the batch. This is used by Steam to support
+ * [Dynamic Cloud Sync](https://steamcommunity.com/groups/steamworks/announcements/detail/3142949576401813670)
+ * ; users can save data on one PC, put the device to sleep, and then continue
+ * playing on another PC (and vice versa) with the save data fully
+ * synchronized across all devices, allowing for a seamless experience without
+ * having to do full restarts of the program.
+ *
+ * ## Notes on valid paths
+ *
+ * All paths in the Storage API use Unix-style path separators ('/'). Using a
+ * different path separator will not work, even if the underlying platform
+ * would otherwise accept it. This is to keep code using the Storage API
+ * portable between platforms and Storage implementations and simplify app
+ * code.
+ *
+ * Paths with relative directories ("." and "..") are forbidden by the Storage
+ * API.
+ *
+ * All valid UTF-8 strings (discounting the NULL terminator character and the
+ * '/' path separator) are usable for filenames, however, an underlying
+ * Storage implementation may not support particularly strange sequences and
+ * refuse to create files with those names, etc.

+ * Technical details, not for the wiki (hello, header readers!)...
+ *
+ * On Windows (and maybe other platforms), a program might use a different
+ * C runtime than its libraries. Or, in SDL's case, it might use a C runtime
+ * while SDL uses none at all.
+ *
+ * C runtimes expect to initialize thread-specific details when a new thread
+ * is created, but to do this in SDL_CreateThread would require SDL to know
+ * intimate details about the caller's C runtime, which is not possible.
+ *
+ * So SDL_CreateThread has two extra parameters, which are
+ * hidden at compile time by macros: the C runtime's `_beginthreadex` and
+ * `_endthreadex` entry points. If these are not NULL, they are used to spin
+ * and terminate the new thread; otherwise the standard Win32 `CreateThread`
+ * function is used. When `SDL_CreateThread` is called from a compiler that
+ * needs this C runtime thread init function, macros insert the appropriate
+ * function pointers for SDL_CreateThread's caller (which might be a different
+ * compiler with a different runtime in different calls to SDL_CreateThread!).
+ *
+ * SDL_BeginThreadFunction defaults to `_beginthreadex` on Windows (and NULL
+ * everywhere else), but apps that have extremely specific special needs can
+ * define this to something else and the SDL headers will use it, passing the
+ * app-defined value to SDL_CreateThread calls. Redefine this with caution!
+ *
+ * Platforms that don't need _beginthread stuff (most everything) will fail
+ * SDL_CreateThread with an error if these pointers _aren't_ NULL.
+ *
+ * Unless you are doing something extremely complicated, like perhaps a
+ * language binding, **you should never deal with this directly**. Let SDL's
+ * macros handle this platform-specific detail transparently!

+ * - `SDL_PROP_THREAD_CREATE_USERDATA_POINTER`: an arbitrary app-defined

+ * - `SDL_PROP_THREAD_CREATE_STACKSIZE_NUMBER`: the size, in bytes, of the new

+ *
+ * SDL makes an attempt to report `SDL_PROP_THREAD_CREATE_NAME_STRING` to the
+ * system, so that debuggers can display it. Not all platforms support this.

+ * Thread naming is a little complicated: Most systems have very small limits

+ *
+ * https://stackoverflow.com/questions/149932/naming-conventions-for-threads
+ *
+ * If a system imposes requirements, SDL will try to munge the string for it
+ * (truncate, etc), but the original string contents will be available from
+ * SDL_GetThreadName().
+ *
+ * The size (in bytes) of the new stack can be specified with
+ * `SDL_PROP_THREAD_CREATE_STACKSIZE_NUMBER`. Zero means "use the system
+ * default" which might be wildly different between platforms. x86 Linux
+ * generally defaults to eight megabytes, an embedded device might be a few
+ * kilobytes instead. You generally need to specify a stack that is a multiple

+ * # CategoryVideo
+ *
+ * SDL's video subsystem is largely interested in abstracting window
+ * management from the underlying operating system. You can create windows,
+ * manage them in various ways, set them fullscreen, and get events when
+ * interesting things happen with them, such as the mouse or keyboard
+ * interacting with a window.
+ *
+ * The video subsystem is also interested in abstracting away some
+ * platform-specific differences in OpenGL: context creation, swapping
+ * buffers, etc. This may be crucial to your app, but also you are not
+ * required to use OpenGL at all. In fact, SDL can provide rendering to those
+ * windows as well, either with an easy-to-use
+ * [2D API](https://wiki.libsdl.org/SDL3/CategoryRender)
+ * or with a more-powerful
+ * [GPU API](https://wiki.libsdl.org/SDL3/CategoryGPU)
+ * . Of course, it can simply get out of your way and give you the window
+ * handles you need to use Vulkan, Direct3D, Metal, or whatever else you like
+ * directly, too.
+ *
+ * The video subsystem covers a lot of functionality, out of necessity, so it
+ * is worth perusing the list of functions just to see what's available, but
+ * most apps can get by with simply creating a window and listening for
+ * events, so start with SDL_CreateWindow() and SDL_PollEvent().

+ *
+ * There are some quirks to looking up OpenGL functions that require some
+ * extra care from the application. If you code carefully, you can handle
+ * these quirks without any platform-specific code, though:
+ *
+ * - On Windows, function pointers are specific to the current GL context;
+ *   this means you need to have created a GL context and made it current
+ *   before calling SDL_GL_GetProcAddress(). If you recreate your context or
+ *   create a second context, you should assume that any existing function
+ *   pointers aren't valid to use with it. This is (currently) a
+ *   Windows-specific limitation, and in practice lots of drivers don't suffer
+ *   this limitation, but it is still the way the wgl API is documented to
+ *   work and you should expect crashes if you don't respect it. Store a copy
+ *   of the function pointers that comes and goes with context lifespan.
+ * - On X11, function pointers returned by this function are valid for any
+ *   context, and can even be looked up before a context is created at all.
+ *   This means that, for at least some common OpenGL implementations, if you
+ *   look up a function that doesn't exist, you'll get a non-NULL result that
+ *   is _NOT_ safe to call. You must always make sure the function is actually
+ *   available for a given GL context before calling it, by checking for the
+ *   existence of the appropriate extension with SDL_GL_ExtensionSupported(),
+ *   or verifying that the version of OpenGL you're using offers the function
+ *   as core functionality.
+ * - Some OpenGL drivers, on all platforms, *will* return NULL if a function
+ *   isn't supported, but you can't count on this behavior. Check for
+ *   extensions you use, and if you get a NULL anyway, act as if that
+ *   extension wasn't available. This is probably a bug in the driver, but you
+ *   can code defensively for this scenario anyhow.
+ * - Just because you're on Linux/Unix, don't assume you'll be using X11.
+ *   Next-gen display servers are waiting to replace it, and may or may not
+ *   make the same promises about function pointers.
+ * - OpenGL function pointers must be declared `APIENTRY` as in the example
+ *   code. This will ensure the proper calling convention is followed on

+ * is eventually paired with an equivalent number of calls to

+ * library currently loaded, and and the library isn't actually unloaded until
+ * there have been an equivalent number of calls to SDL_Vulkan_UnloadLibrary.
+ *
+ * It is fairly common for Vulkan applications to link with libvulkan instead
+ * of explicitly loading it at run time. This will work with SDL provided the
+ * application links to a dynamic library and both it and SDL use the same
+ * search path.

+ * to the same vulkan loader library the application linked to.
+ *
+ * On Apple devices, if `path` is NULL, SDL will attempt to find the
+ * `vkGetInstanceProcAddr` address within all the Mach-O images of the current
+ * process. This is because it is fairly common for Vulkan applications to
+ * link with libvulkan (and historically MoltenVK was provided as a static
+ * library). If it is not found, on macOS, SDL will attempt to load
+ * `vulkan.framework/vulkan`, `libvulkan.1.dylib`,

+ * iOS, SDL will attempt to load `libMoltenVK.dylib`. Applications using a
+ * dynamic framework or .dylib must ensure it is included in its application
+ * bundle.
