2199     *
2200     *   - In loader interface v1:
2201     *       - The first ICD entrypoint called by the loader is
2202     *         vk_icdGetInstanceProcAddr(). The ICD must statically expose this
2203     *         entrypoint.
2204     *       - The ICD must statically expose no other Vulkan symbol unless it
2205     * is linked with -Bsymbolic.
2206     *       - Each dispatchable Vulkan handle created by the ICD must be
2207     *         a pointer to a struct whose first member is VK_LOADER_DATA. The
2208     *         ICD must initialize VK_LOADER_DATA.loadMagic to
2209     * ICD_LOADER_MAGIC.
2210     *       - The loader implements vkCreate{PLATFORM}SurfaceKHR() and
2211     *         vkDestroySurfaceKHR(). The ICD must be capable of working with
2212     *         such loader-managed surfaces.
2213     *
2214     *    - Loader interface v2 differs from v1 in:
2215     *       - The first ICD entrypoint called by the loader is
2216     *         vk_icdNegotiateLoaderICDInterfaceVersion(). The ICD must
2217     *         statically expose this entrypoint.
2218     *
2219     *    - Loader interface v3 differs from v2 in:
2220     *        - The ICD must implement vkCreate{PLATFORM}SurfaceKHR(),
2221     *          vkDestroySurfaceKHR(), and other API which uses VKSurfaceKHR,
2222     *          because the loader no longer does so.
