1900     *
1901     *   - Loader interface v0 is incompatible with later versions. We don't
1902     *     support it.
1903     *
1904     *   - In loader interface v1:
1905     *       - The first ICD entrypoint called by the loader is
1906     *         vk_icdGetInstanceProcAddr(). The ICD must statically expose this
1907     *         entrypoint.
1908     *       - The ICD must statically expose no other Vulkan symbol unless it
1909     * is linked with -Bsymbolic.
1910     *       - Each dispatchable Vulkan handle created by the ICD must be
1911     *         a pointer to a struct whose first member is VK_LOADER_DATA. The
1912     *         ICD must initialize VK_LOADER_DATA.loadMagic to
1913     * ICD_LOADER_MAGIC.
1914     *       - The loader implements vkCreate{PLATFORM}SurfaceKHR() and
1915     *         vkDestroySurfaceKHR(). The ICD must be capable of working with
1916     *         such loader-managed surfaces.
1917     *
1918     *    - Loader interface v2 differs from v1 in:
1919     *       - The first ICD entrypoint called by the loader is
1920     *         vk_icdNegotiateLoaderICDInterfaceVersion(). The ICD must
1921     *         statically expose this entrypoint.
1922     *
1923     *    - Loader interface v3 differs from v2 in:
1924     *        - The ICD must implement vkCreate{PLATFORM}SurfaceKHR(),
1925     *          vkDestroySurfaceKHR(), and other API which uses VKSurfaceKHR,
1926     *          because the loader no longer does so.
