3979 * entrypoint.
3980 * - The ICD must statically expose no other Vulkan symbol unless it is
3981 * linked with -Bsymbolic.
3982 * - Each dispatchable Vulkan handle created by the ICD must be
3983 * a pointer to a struct whose first member is VK_LOADER_DATA. The
3984 * ICD must initialize VK_LOADER_DATA.loadMagic to ICD_LOADER_MAGIC.
3985 * - The loader implements vkCreate{PLATFORM}SurfaceKHR() and
3986 * vkDestroySurfaceKHR(). The ICD must be capable of working with
3987 * such loader-managed surfaces.
3988 *
3989 * - Loader interface v2 differs from v1 in:
3990 * - The first ICD entrypoint called by the loader is
3991 * vk_icdNegotiateLoaderICDInterfaceVersion(). The ICD must
3992 * statically expose this entrypoint.
3993 *
3994 * - Loader interface v3 differs from v2 in:
3995 * - The ICD must implement vkCreate{PLATFORM}SurfaceKHR(),
3996 * vkDestroySurfaceKHR(), and other API which uses VKSurfaceKHR,
3997 * because the loader no longer does so.
