2285     *   - In loader interface v1:
2286     *       - The first ICD entrypoint called by the loader is
2287     *         vk_icdGetInstanceProcAddr(). The ICD must statically expose this
2288     *         entrypoint.
2289     *       - The ICD must statically expose no other Vulkan symbol unless it
2290     * is linked with -Bsymbolic.
2291     *       - Each dispatchable Vulkan handle created by the ICD must be
2292     *         a pointer to a struct whose first member is VK_LOADER_DATA. The
2293     *         ICD must initialize VK_LOADER_DATA.loadMagic to
2294     * ICD_LOADER_MAGIC.
2295     *       - The loader implements vkCreate{PLATFORM}SurfaceKHR() and
2296     *         vkDestroySurfaceKHR(). The ICD must be capable of working with
2297     *         such loader-managed surfaces.
2298     *
2299     *    - Loader interface v2 differs from v1 in:
2300     *       - The first ICD entrypoint called by the loader is
2301     *         vk_icdNegotiateLoaderICDInterfaceVersion(). The ICD must
2302     *         statically expose this entrypoint.
2303     *
2304     *    - Loader interface v3 differs from v2 in:
2305     *        - The ICD must implement vkCreate{PLATFORM}SurfaceKHR(),
2306     *          vkDestroySurfaceKHR(), and other API which uses VKSurfaceKHR,
2307     *          because the loader no longer does so.
