2196     *         vk_icdGetInstanceProcAddr(). The ICD must statically expose this
2197     *         entrypoint.
2198     *       - The ICD must statically expose no other Vulkan symbol unless it is
2199     *         linked with -Bsymbolic.
2200     *       - Each dispatchable Vulkan handle created by the ICD must be
2201     *         a pointer to a struct whose first member is VK_LOADER_DATA. The
2202     *         ICD must initialize VK_LOADER_DATA.loadMagic to ICD_LOADER_MAGIC.
2203     *       - The loader implements vkCreate{PLATFORM}SurfaceKHR() and
2204     *         vkDestroySurfaceKHR(). The ICD must be capable of working with
2205     *         such loader-managed surfaces.
2206     *
2207     *    - Loader interface v2 differs from v1 in:
2208     *       - The first ICD entrypoint called by the loader is
2209     *         vk_icdNegotiateLoaderICDInterfaceVersion(). The ICD must
2210     *         statically expose this entrypoint.
2211     *
2212     *    - Loader interface v3 differs from v2 in:
2213     *        - The ICD must implement vkCreate{PLATFORM}SurfaceKHR(),
2214     *          vkDestroySurfaceKHR(), and other API which uses VKSurfaceKHR,
2215     *          because the loader no longer does so.
