2222     *   - In loader interface v1:
2223     *       - The first ICD entrypoint called by the loader is
2224     *         vk_icdGetInstanceProcAddr(). The ICD must statically expose this
2225     *         entrypoint.
2226     *       - The ICD must statically expose no other Vulkan symbol unless it
2227     * is linked with -Bsymbolic.
2228     *       - Each dispatchable Vulkan handle created by the ICD must be
2229     *         a pointer to a struct whose first member is VK_LOADER_DATA. The
2230     *         ICD must initialize VK_LOADER_DATA.loadMagic to
2231     * ICD_LOADER_MAGIC.
2232     *       - The loader implements vkCreate{PLATFORM}SurfaceKHR() and
2233     *         vkDestroySurfaceKHR(). The ICD must be capable of working with
2234     *         such loader-managed surfaces.
2235     *
2236     *    - Loader interface v2 differs from v1 in:
2237     *       - The first ICD entrypoint called by the loader is
2238     *         vk_icdNegotiateLoaderICDInterfaceVersion(). The ICD must
2239     *         statically expose this entrypoint.
2240     *
2241     *    - Loader interface v3 differs from v2 in:
2242     *        - The ICD must implement vkCreate{PLATFORM}SurfaceKHR(),
2243     *          vkDestroySurfaceKHR(), and other API which uses VKSurfaceKHR,
2244     *          because the loader no longer does so.
