/**
 * # 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().

/**
 * Create a window with the specified properties.
 *
 * The window size is a request and may be different than expected based on

 *   with grabbed mouse focus
 * - `SDL_PROP_WINDOW_CREATE_OPENGL_BOOLEAN`: true if the window will be used
 *   with OpenGL rendering
 * - `SDL_PROP_WINDOW_CREATE_PARENT_POINTER`: an SDL_Window that will be the
 *   parent of this window, required for windows with the "tooltip", "menu",
 *   and "modal" properties
 * - `SDL_PROP_WINDOW_CREATE_RESIZABLE_BOOLEAN`: true if the window should be
 *   resizable
 * - `SDL_PROP_WINDOW_CREATE_TITLE_STRING`: the title of the window, in UTF-8
 *   encoding

 * - `SDL_PROP_WINDOW_CREATE_WIDTH_NUMBER`: the width of the window
 * - `SDL_PROP_WINDOW_CREATE_X_NUMBER`: the x position of the window, or
 *   `SDL_WINDOWPOS_CENTERED`, defaults to `SDL_WINDOWPOS_UNDEFINED`. This is
 *   relative to the parent for windows with the "tooltip" or "menu" property
 *   set.
 * - `SDL_PROP_WINDOW_CREATE_Y_NUMBER`: the y position of the window, or
 *   `SDL_WINDOWPOS_CENTERED`, defaults to `SDL_WINDOWPOS_UNDEFINED`. This is
 *   relative to the parent for windows with the "tooltip" or "menu" property
 *   set.
 *
 * These are additional supported properties on macOS:
 *
 * - `SDL_PROP_WINDOW_CREATE_COCOA_WINDOW_POINTER`: the
 *   `(__unsafe_unretained)` NSWindow associated with the window, if you want
 *   to wrap an existing window.
 * - `SDL_PROP_WINDOW_CREATE_COCOA_VIEW_POINTER`: the `(__unsafe_unretained)`
 *   NSView associated with the window, defaults to `[window contentView]`
 *
 * These are additional supported properties on iOS, tvOS, and visionOS:
 *
 * - `SDL_PROP_WINDOW_CREATE_WINDOWSCENE_POINTER`: the `(__unsafe_unretained)`
 *   UIWindowScene associated with the window, defaults to the active window
 *   scene.
 *
 * These are additional supported properties on Wayland:
 *
 * - `SDL_PROP_WINDOW_CREATE_WAYLAND_SURFACE_ROLE_CUSTOM_BOOLEAN` - true if
 *   the application wants to use the Wayland surface for a custom role and
 *   does not want it attached to an XDG toplevel window. See
 *   [README-wayland](README-wayland) for more information on using custom
 *   surfaces.
 * - `SDL_PROP_WINDOW_CREATE_WAYLAND_CREATE_EGL_WINDOW_BOOLEAN` - true if the
 *   application wants an associated `wl_egl_window` object to be created and
 *   attached to the window, even if the window does not have the OpenGL
 *   property or `SDL_WINDOW_OPENGL` flag set.
 * - `SDL_PROP_WINDOW_CREATE_WAYLAND_WL_SURFACE_POINTER` - the wl_surface
 *   associated with the window, if you want to wrap an existing window. See
 *   [README-wayland](README-wayland) for more information.
 *
 * These are additional supported properties on Windows:
 *
 * - `SDL_PROP_WINDOW_CREATE_WIN32_HWND_POINTER`: the HWND associated with the
 *   window, if you want to wrap an existing window.
 * - `SDL_PROP_WINDOW_CREATE_WIN32_PIXEL_FORMAT_HWND_POINTER`: optional,
 *   another window to share pixel format with, useful for OpenGL windows
 *
 * These are additional supported properties with X11:
 *
 * - `SDL_PROP_WINDOW_CREATE_X11_WINDOW_NUMBER`: the X11 Window associated
 *   with the window, if you want to wrap an existing window.
 *
 * The window is implicitly shown if the "hidden" property is not set.
 *
 * These are additional supported properties with Emscripten:
 *
 * - `SDL_PROP_WINDOW_CREATE_EMSCRIPTEN_CANVAS_ID_STRING`: the id given to the
 *   canvas element. This should start with a '#' sign
 * - `SDL_PROP_WINDOW_CREATE_EMSCRIPTEN_KEYBOARD_ELEMENT_STRING`: override the
 *   binding element for keyboard inputs for this canvas. The variable can be
 *   one of:
 * - "#window": the javascript window object (default)
 * - "#document": the javascript document object
 * - "#screen": the javascript window.screen object
 * - "#canvas": the WebGL canvas element
 * - "#none": Don't bind anything at all
 * - any other string without a leading # sign applies to the element on the
 *   page with that ID. Windows with the "tooltip" and "menu" properties are
 *   popup windows and have the behaviors and guidelines outlined in
 *   SDL_CreatePopupWindow().
 *
 * These are additional supported properties with visionOS:
 *
 * - `SDL_PROP_WINDOW_CREATE_CURVATURE_FLOAT`: the curvature of the window on
 *   visionOS. Curved windows have square corners and additional controls for
 *   more immersive gaming. This can be -1 (disabled), which is the default, 0
 *   (no curve), or set to a specific curvature radius in millimeters. A
 *   common value for a gaming monitor is 1000.
 *
 * If this window is being created to be used with an SDL_Renderer, you should
 * not add a graphics API specific property
 * (`SDL_PROP_WINDOW_CREATE_OPENGL_BOOLEAN`, etc), as SDL will handle that
 * internally when it chooses a renderer. However, SDL might need to recreate
 * your window at that point, which may cause the window to appear briefly,
 * and then flicker as it is recreated. The correct approach to this is to
 * create the window with the `SDL_PROP_WINDOW_CREATE_HIDDEN_BOOLEAN` property
 * set to true, then create the renderer, then show the window with
 * SDL_ShowWindow().
 *
 * \param props the properties to use.
 * \returns the window that was created or NULL on failure; call
 *          SDL_GetError() for more information.

 * Get an OpenGL function by name.
 *
 * If the GL library is loaded at runtime with SDL_GL_LoadLibrary(), then all

 * function pointers to OpenGL extensions.
 *
 * 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
 *   platforms where this matters (Win32) thereby avoiding stack corruption.
