1891     *
1892     *   - Loader interface v0 is incompatible with later versions. We don't
1893     *     support it.
1894     *
1895     *   - In loader interface v1:
1896     *       - The first ICD entrypoint called by the loader is
1897     *         vk_icdGetInstanceProcAddr(). The ICD must statically expose this
1898     *         entrypoint.
1899     *       - The ICD must statically expose no other Vulkan symbol unless it
1900     * is linked with -Bsymbolic.
1901     *       - Each dispatchable Vulkan handle created by the ICD must be
1902     *         a pointer to a struct whose first member is VK_LOADER_DATA. The
1903     *         ICD must initialize VK_LOADER_DATA.loadMagic to
1904     * ICD_LOADER_MAGIC.
1905     *       - The loader implements vkCreate{PLATFORM}SurfaceKHR() and
1906     *         vkDestroySurfaceKHR(). The ICD must be capable of working with
1907     *         such loader-managed surfaces.
1908     *
1909     *    - Loader interface v2 differs from v1 in:
1910     *       - The first ICD entrypoint called by the loader is
1911     *         vk_icdNegotiateLoaderICDInterfaceVersion(). The ICD must
1912     *         statically expose this entrypoint.
1913     *
1914     *    - Loader interface v3 differs from v2 in:
1915     *        - The ICD must implement vkCreate{PLATFORM}SurfaceKHR(),
1916     *          vkDestroySurfaceKHR(), and other API which uses VKSurfaceKHR,
1917     *          because the loader no longer does so.
