2013     * What follows is a condensed summary, to help you navigate the large and
2014     * confusing official doc.
2015     *
2016     *   - Loader interface v0 is incompatible with later versions. We don't
2017     *     support it.
2018     *
2019     *   - In loader interface v1:
2020     *       - The first ICD entrypoint called by the loader is
2021     *         vk_icdGetInstanceProcAddr(). The ICD must statically expose this
2022     *         entrypoint.
2023     *       - The ICD must statically expose no other Vulkan symbol unless it is
2024     *         linked with -Bsymbolic.
2025     *       - Each dispatchable Vulkan handle created by the ICD must be
2026     *         a pointer to a struct whose first member is VK_LOADER_DATA. The
2027     *         ICD must initialize VK_LOADER_DATA.loadMagic to ICD_LOADER_MAGIC.
2028     *       - The loader implements vkCreate{PLATFORM}SurfaceKHR() and
2029     *         vkDestroySurfaceKHR(). The ICD must be capable of working with
2030     *         such loader-managed surfaces.
2031     *
2032     *    - Loader interface v2 differs from v1 in:
2033     *       - The first ICD entrypoint called by the loader is
2034     *         vk_icdNegotiateLoaderICDInterfaceVersion(). The ICD must
2035     *         statically expose this entrypoint.
2036     *
2037     *    - Loader interface v3 differs from v2 in:
2038     *        - The ICD must implement vkCreate{PLATFORM}SurfaceKHR(),
2039     *          vkDestroySurfaceKHR(), and other API which uses VKSurfaceKHR,
2040     *          because the loader no longer does so.
