1935     *
1936     *   - In loader interface v1:
1937     *       - The first ICD entrypoint called by the loader is
1938     *         vk_icdGetInstanceProcAddr(). The ICD must statically expose this
1939     *         entrypoint.
1940     *       - The ICD must statically expose no other Vulkan symbol unless it
1941     * is linked with -Bsymbolic.
1942     *       - Each dispatchable Vulkan handle created by the ICD must be
1943     *         a pointer to a struct whose first member is VK_LOADER_DATA. The
1944     *         ICD must initialize VK_LOADER_DATA.loadMagic to
1945     * ICD_LOADER_MAGIC.
1946     *       - The loader implements vkCreate{PLATFORM}SurfaceKHR() and
1947     *         vkDestroySurfaceKHR(). The ICD must be capable of working with
1948     *         such loader-managed surfaces.
1949     *
1950     *    - Loader interface v2 differs from v1 in:
1951     *       - The first ICD entrypoint called by the loader is
1952     *         vk_icdNegotiateLoaderICDInterfaceVersion(). The ICD must
1953     *         statically expose this entrypoint.
1954     *
1955     *    - Loader interface v3 differs from v2 in:
1956     *        - The ICD must implement vkCreate{PLATFORM}SurfaceKHR(),
1957     *          vkDestroySurfaceKHR(), and other API which uses VKSurfaceKHR,
1958     *          because the loader no longer does so.
