2252     *   - In loader interface v1:
2253     *       - The first ICD entrypoint called by the loader is
2254     *         vk_icdGetInstanceProcAddr(). The ICD must statically expose this
2255     *         entrypoint.
2256     *       - The ICD must statically expose no other Vulkan symbol unless it
2257     * is linked with -Bsymbolic.
2258     *       - Each dispatchable Vulkan handle created by the ICD must be
2259     *         a pointer to a struct whose first member is VK_LOADER_DATA. The
2260     *         ICD must initialize VK_LOADER_DATA.loadMagic to
2261     * ICD_LOADER_MAGIC.
2262     *       - The loader implements vkCreate{PLATFORM}SurfaceKHR() and
2263     *         vkDestroySurfaceKHR(). The ICD must be capable of working with
2264     *         such loader-managed surfaces.
2265     *
2266     *    - Loader interface v2 differs from v1 in:
2267     *       - The first ICD entrypoint called by the loader is
2268     *         vk_icdNegotiateLoaderICDInterfaceVersion(). The ICD must
2269     *         statically expose this entrypoint.
2270     *
2271     *    - Loader interface v3 differs from v2 in:
2272     *        - The ICD must implement vkCreate{PLATFORM}SurfaceKHR(),
2273     *          vkDestroySurfaceKHR(), and other API which uses VKSurfaceKHR,
2274     *          because the loader no longer does so.
