2480     *   - In loader interface v1:
2481     *       - The first ICD entrypoint called by the loader is
2482     *         vk_icdGetInstanceProcAddr(). The ICD must statically expose this
2483     *         entrypoint.
2484     *       - The ICD must statically expose no other Vulkan symbol unless it
2485     * is linked with -Bsymbolic.
2486     *       - Each dispatchable Vulkan handle created by the ICD must be
2487     *         a pointer to a struct whose first member is VK_LOADER_DATA. The
2488     *         ICD must initialize VK_LOADER_DATA.loadMagic to
2489     * ICD_LOADER_MAGIC.
2490     *       - The loader implements vkCreate{PLATFORM}SurfaceKHR() and
2491     *         vkDestroySurfaceKHR(). The ICD must be capable of working with
2492     *         such loader-managed surfaces.
2493     *
2494     *    - Loader interface v2 differs from v1 in:
2495     *       - The first ICD entrypoint called by the loader is
2496     *         vk_icdNegotiateLoaderICDInterfaceVersion(). The ICD must
2497     *         statically expose this entrypoint.
2498     *
2499     *    - Loader interface v3 differs from v2 in:
2500     *        - The ICD must implement vkCreate{PLATFORM}SurfaceKHR(),
2501     *          vkDestroySurfaceKHR(), and other API which uses VKSurfaceKHR,
2502     *          because the loader no longer does so.
