2053     *
2054     *   - In loader interface v1:
2055     *       - The first ICD entrypoint called by the loader is
2056     *         vk_icdGetInstanceProcAddr(). The ICD must statically expose this
2057     *         entrypoint.
2058     *       - The ICD must statically expose no other Vulkan symbol unless it
2059     * is linked with -Bsymbolic.
2060     *       - Each dispatchable Vulkan handle created by the ICD must be
2061     *         a pointer to a struct whose first member is VK_LOADER_DATA. The
2062     *         ICD must initialize VK_LOADER_DATA.loadMagic to
2063     * ICD_LOADER_MAGIC.
2064     *       - The loader implements vkCreate{PLATFORM}SurfaceKHR() and
2065     *         vkDestroySurfaceKHR(). The ICD must be capable of working with
2066     *         such loader-managed surfaces.
2067     *
2068     *    - Loader interface v2 differs from v1 in:
2069     *       - The first ICD entrypoint called by the loader is
2070     *         vk_icdNegotiateLoaderICDInterfaceVersion(). The ICD must
2071     *         statically expose this entrypoint.
2072     *
2073     *    - Loader interface v3 differs from v2 in:
2074     *        - The ICD must implement vkCreate{PLATFORM}SurfaceKHR(),
2075     *          vkDestroySurfaceKHR(), and other API which uses VKSurfaceKHR,
2076     *          because the loader no longer does so.
