+ * This function loads dynamic libraries that SDL_image needs, and prepares

+ *
+ * Flags should be one or more flags from IMG_InitFlags OR'd together. It

+ *
+ * - `_INIT_JPG`

+ * - `_INIT_WEBP`
+ * - `_INIT_JXL`
+ * - `_INIT_AVIF`
+ *
+ * More flags may be added in a future SDL_image release.
+ *
+ * This function may need to load external shared libraries to support various
+ * codecs, which means this function can fail to initialize that support on an
+ * otherwise-reasonable system if the library isn't available; this is not
+ * just a question of exceptional circumstances like running out of memory at
+ * startup!
+ *
+ * Note that you may call this function more than once to initialize with
+ * additional flags. The return value will reflect both new flags that
+ * successfully initialized, and also include flags that had previously been
+ * initialized as well.
+ *
+ * As this will return previously-initialized flags, it's legal to call this
+ * with zero (no flags set). This is a safe no-op that can be used to query
+ * the current initialization state without changing it at all.
+ *
+ * Since this returns previously-initialized flags as well as new ones, and
+ * you can call this with zero, you should not check for a zero return value
+ * to determine an error condition. Instead, you should check to make sure all
+ * the flags you require are set in the return value. If you have a game with
+ * data in a specific format, this might be a fatal error. If you're a generic
+ * image displaying app, perhaps you are fine with only having JPG and PNG
+ * support and can live without WEBP, even if you request support for
+ * everything.
+ *
+ * Unlike other SDL satellite libraries, calls to IMG_Init do not stack; a
+ * single call to IMG_Quit() will deinitialize everything and does not have to
+ * be paired with a matching IMG_Init call. For that reason, it's considered
+ * best practices to have a single IMG_Init and IMG_Quit call in your program.
+ * While this isn't required, be aware of the risks of deviating from that
