2214     *
2215     *   - In loader interface v1:
2216     *       - The first ICD entrypoint called by the loader is
2217     *         vk_icdGetInstanceProcAddr(). The ICD must statically expose this
2218     *         entrypoint.
2219     *       - The ICD must statically expose no other Vulkan symbol unless it
2220     * is linked with -Bsymbolic.
2221     *       - Each dispatchable Vulkan handle created by the ICD must be
2222     *         a pointer to a struct whose first member is VK_LOADER_DATA. The
2223     *         ICD must initialize VK_LOADER_DATA.loadMagic to
2224     * ICD_LOADER_MAGIC.
2225     *       - The loader implements vkCreate{PLATFORM}SurfaceKHR() and
2226     *         vkDestroySurfaceKHR(). The ICD must be capable of working with
2227     *         such loader-managed surfaces.
2228     *
2229     *    - Loader interface v2 differs from v1 in:
2230     *       - The first ICD entrypoint called by the loader is
2231     *         vk_icdNegotiateLoaderICDInterfaceVersion(). The ICD must
2232     *         statically expose this entrypoint.
2233     *
2234     *    - Loader interface v3 differs from v2 in:
2235     *        - The ICD must implement vkCreate{PLATFORM}SurfaceKHR(),
2236     *          vkDestroySurfaceKHR(), and other API which uses VKSurfaceKHR,
2237     *          because the loader no longer does so.
