2277     *   - In loader interface v1:
2278     *       - The first ICD entrypoint called by the loader is
2279     *         vk_icdGetInstanceProcAddr(). The ICD must statically expose this
2280     *         entrypoint.
2281     *       - The ICD must statically expose no other Vulkan symbol unless it
2282     * is linked with -Bsymbolic.
2283     *       - Each dispatchable Vulkan handle created by the ICD must be
2284     *         a pointer to a struct whose first member is VK_LOADER_DATA. The
2285     *         ICD must initialize VK_LOADER_DATA.loadMagic to
2286     * ICD_LOADER_MAGIC.
2287     *       - The loader implements vkCreate{PLATFORM}SurfaceKHR() and
2288     *         vkDestroySurfaceKHR(). The ICD must be capable of working with
2289     *         such loader-managed surfaces.
2290     *
2291     *    - Loader interface v2 differs from v1 in:
2292     *       - The first ICD entrypoint called by the loader is
2293     *         vk_icdNegotiateLoaderICDInterfaceVersion(). The ICD must
2294     *         statically expose this entrypoint.
2295     *
2296     *    - Loader interface v3 differs from v2 in:
2297     *        - The ICD must implement vkCreate{PLATFORM}SurfaceKHR(),
2298     *          vkDestroySurfaceKHR(), and other API which uses VKSurfaceKHR,
2299     *          because the loader no longer does so.
