- * - `SDL_WINDOW_MAXIMIZED`: window is maximized
- * - `SDL_WINDOW_INPUT_GRABBED`: window has grabbed input focus
- * - `SDL_WINDOW_ALLOW_HIGHDPI`: window should be created in high-DPI mode if
- * supported (>= SDL 2.0.1)
- *
- * `SDL_WINDOW_SHOWN` is ignored by SDL_CreateWindow(). The SDL_Window is
- * implicitly shown if SDL_WINDOW_HIDDEN is not set. `SDL_WINDOW_SHOWN` may be
- * queried later using SDL_GetWindowFlags().
- *
- * On Apple's macOS, you **must** set the NSHighResolutionCapable Info.plist
- * property to YES, otherwise you will not receive a High-DPI OpenGL canvas.
- *
- * If the window is created with the `SDL_WINDOW_ALLOW_HIGHDPI` flag, its size
- * in pixels may differ from its size in screen coordinates on platforms with
- * high-DPI support (e.g. iOS and macOS). Use SDL_GetWindowSize() to query the
- * client area's size in screen coordinates, and SDL_GL_GetDrawableSize() or
- * SDL_GetRendererOutputSize() to query the drawable size in pixels.
- *
- * If the window is set fullscreen, the width and height parameters `w` and
- * `h` will not be used. However, invalid size parameters (e.g. too large) may
- * still fail. Window size is actually limited to 16384 x 16384 for all
- * platforms at window creation.
- *
- * If the window is created with any of the SDL_WINDOW_OPENGL or
- * SDL_WINDOW_VULKAN flags, then the corresponding LoadLibrary function
- * (SDL_GL_LoadLibrary or SDL_Vulkan_LoadLibrary) is called and the
- * corresponding UnloadLibrary function is called by SDL_DestroyWindow().
- *
- * If SDL_WINDOW_VULKAN is specified and there isn't a working Vulkan driver,
- * SDL_CreateWindow() will fail because SDL_Vulkan_LoadLibrary() will fail.
- *
- * If SDL_WINDOW_METAL is specified on an OS that does not support Metal,
- * SDL_CreateWindow() will fail.

- * loader or link to a dynamic library version. This limitation may be removed

- *
- * 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.
