2196     *
2197     *   - In loader interface v1:
2198     *       - The first ICD entrypoint called by the loader is
2199     *         vk_icdGetInstanceProcAddr(). The ICD must statically expose this
2200     *         entrypoint.
2201     *       - The ICD must statically expose no other Vulkan symbol unless it
2202     * is linked with -Bsymbolic.
2203     *       - Each dispatchable Vulkan handle created by the ICD must be
2204     *         a pointer to a struct whose first member is VK_LOADER_DATA. The
2205     *         ICD must initialize VK_LOADER_DATA.loadMagic to
2206     * ICD_LOADER_MAGIC.
2207     *       - The loader implements vkCreate{PLATFORM}SurfaceKHR() and
2208     *         vkDestroySurfaceKHR(). The ICD must be capable of working with
2209     *         such loader-managed surfaces.
2210     *
2211     *    - Loader interface v2 differs from v1 in:
2212     *       - The first ICD entrypoint called by the loader is
2213     *         vk_icdNegotiateLoaderICDInterfaceVersion(). The ICD must
2214     *         statically expose this entrypoint.
2215     *
2216     *    - Loader interface v3 differs from v2 in:
2217     *        - The ICD must implement vkCreate{PLATFORM}SurfaceKHR(),
2218     *          vkDestroySurfaceKHR(), and other API which uses VKSurfaceKHR,
2219     *          because the loader no longer does so.
