2004     * What follows is a condensed summary, to help you navigate the large and
2005     * confusing official doc.
2006     *
2007     *   - Loader interface v0 is incompatible with later versions. We don't
2008     *     support it.
2009     *
2010     *   - In loader interface v1:
2011     *       - The first ICD entrypoint called by the loader is
2012     *         vk_icdGetInstanceProcAddr(). The ICD must statically expose this
2013     *         entrypoint.
2014     *       - The ICD must statically expose no other Vulkan symbol unless it
2015     * is linked with -Bsymbolic.
2016     *       - Each dispatchable Vulkan handle created by the ICD must be
2017     *         a pointer to a struct whose first member is VK_LOADER_DATA. The
2018     *         ICD must initialize VK_LOADER_DATA.loadMagic to
2019     * ICD_LOADER_MAGIC.
2020     *       - The loader implements vkCreate{PLATFORM}SurfaceKHR() and
2021     *         vkDestroySurfaceKHR(). The ICD must be capable of working with
2022     *         such loader-managed surfaces.
2023     *
2024     *    - Loader interface v2 differs from v1 in:
2025     *       - The first ICD entrypoint called by the loader is
2026     *         vk_icdNegotiateLoaderICDInterfaceVersion(). The ICD must
2027     *         statically expose this entrypoint.
2028     *
2029     *    - Loader interface v3 differs from v2 in:
2030     *        - The ICD must implement vkCreate{PLATFORM}SurfaceKHR(),
2031     *          vkDestroySurfaceKHR(), and other API which uses VKSurfaceKHR,
2032     *          because the loader no longer does so.
