2015     *
2016     *   - In loader interface v1:
2017     *       - The first ICD entrypoint called by the loader is
2018     *         vk_icdGetInstanceProcAddr(). The ICD must statically expose this
2019     *         entrypoint.
2020     *       - The ICD must statically expose no other Vulkan symbol unless it
2021     * is linked with -Bsymbolic.
2022     *       - Each dispatchable Vulkan handle created by the ICD must be
2023     *         a pointer to a struct whose first member is VK_LOADER_DATA. The
2024     *         ICD must initialize VK_LOADER_DATA.loadMagic to
2025     * ICD_LOADER_MAGIC.
2026     *       - The loader implements vkCreate{PLATFORM}SurfaceKHR() and
2027     *         vkDestroySurfaceKHR(). The ICD must be capable of working with
2028     *         such loader-managed surfaces.
2029     *
2030     *    - Loader interface v2 differs from v1 in:
2031     *       - The first ICD entrypoint called by the loader is
2032     *         vk_icdNegotiateLoaderICDInterfaceVersion(). The ICD must
2033     *         statically expose this entrypoint.
2034     *
2035     *    - Loader interface v3 differs from v2 in:
2036     *        - The ICD must implement vkCreate{PLATFORM}SurfaceKHR(),
2037     *          vkDestroySurfaceKHR(), and other API which uses VKSurfaceKHR,
2038     *          because the loader no longer does so.
