2245     *
2246     *   - In loader interface v1:
2247     *       - The first ICD entrypoint called by the loader is
2248     *         vk_icdGetInstanceProcAddr(). The ICD must statically expose this
2249     *         entrypoint.
2250     *       - The ICD must statically expose no other Vulkan symbol unless it
2251     * is linked with -Bsymbolic.
2252     *       - Each dispatchable Vulkan handle created by the ICD must be
2253     *         a pointer to a struct whose first member is VK_LOADER_DATA. The
2254     *         ICD must initialize VK_LOADER_DATA.loadMagic to
2255     * ICD_LOADER_MAGIC.
2256     *       - The loader implements vkCreate{PLATFORM}SurfaceKHR() and
2257     *         vkDestroySurfaceKHR(). The ICD must be capable of working with
2258     *         such loader-managed surfaces.
2259     *
2260     *    - Loader interface v2 differs from v1 in:
2261     *       - The first ICD entrypoint called by the loader is
2262     *         vk_icdNegotiateLoaderICDInterfaceVersion(). The ICD must
2263     *         statically expose this entrypoint.
2264     *
2265     *    - Loader interface v3 differs from v2 in:
2266     *        - The ICD must implement vkCreate{PLATFORM}SurfaceKHR(),
2267     *          vkDestroySurfaceKHR(), and other API which uses VKSurfaceKHR,
2268     *          because the loader no longer does so.
