1933     *
1934     *   - In loader interface v1:
1935     *       - The first ICD entrypoint called by the loader is
1936     *         vk_icdGetInstanceProcAddr(). The ICD must statically expose this
1937     *         entrypoint.
1938     *       - The ICD must statically expose no other Vulkan symbol unless it
1939     * is linked with -Bsymbolic.
1940     *       - Each dispatchable Vulkan handle created by the ICD must be
1941     *         a pointer to a struct whose first member is VK_LOADER_DATA. The
1942     *         ICD must initialize VK_LOADER_DATA.loadMagic to
1943     * ICD_LOADER_MAGIC.
1944     *       - The loader implements vkCreate{PLATFORM}SurfaceKHR() and
1945     *         vkDestroySurfaceKHR(). The ICD must be capable of working with
1946     *         such loader-managed surfaces.
1947     *
1948     *    - Loader interface v2 differs from v1 in:
1949     *       - The first ICD entrypoint called by the loader is
1950     *         vk_icdNegotiateLoaderICDInterfaceVersion(). The ICD must
1951     *         statically expose this entrypoint.
1952     *
1953     *    - Loader interface v3 differs from v2 in:
1954     *        - The ICD must implement vkCreate{PLATFORM}SurfaceKHR(),
1955     *          vkDestroySurfaceKHR(), and other API which uses VKSurfaceKHR,
1956     *          because the loader no longer does so.
