4467 * entrypoint.
4468 * - The ICD must statically expose no other Vulkan symbol unless it is
4469 * linked with -Bsymbolic.
4470 * - Each dispatchable Vulkan handle created by the ICD must be
4471 * a pointer to a struct whose first member is VK_LOADER_DATA. The
4472 * ICD must initialize VK_LOADER_DATA.loadMagic to ICD_LOADER_MAGIC.
4473 * - The loader implements vkCreate{PLATFORM}SurfaceKHR() and
4474 * vkDestroySurfaceKHR(). The ICD must be capable of working with
4475 * such loader-managed surfaces.
4476 *
4477 * - Loader interface v2 differs from v1 in:
4478 * - The first ICD entrypoint called by the loader is
4479 * vk_icdNegotiateLoaderICDInterfaceVersion(). The ICD must
4480 * statically expose this entrypoint.
4481 *
4482 * - Loader interface v3 differs from v2 in:
4483 * - The ICD must implement vkCreate{PLATFORM}SurfaceKHR(),
4484 * vkDestroySurfaceKHR(), and other API which uses VKSurfaceKHR,
4485 * because the loader no longer does so.
4486 *
4487 * - Loader interface v4 differs from v3 in:
