3528 * The maximum deviation is the sum of the interval over which we

3583 * - Loader interface v0 is incompatible with later versions. We don't
3586 * - In loader interface v1:
3587 * - The first ICD entrypoint called by the loader is
3588 * vk_icdGetInstanceProcAddr(). The ICD must statically expose this
3590 * - The ICD must statically expose no other Vulkan symbol unless it is
3591 * linked with -Bsymbolic.
3592 * - Each dispatchable Vulkan handle created by the ICD must be
3593 * a pointer to a struct whose first member is VK_LOADER_DATA. The
3594 * ICD must initialize VK_LOADER_DATA.loadMagic to ICD_LOADER_MAGIC.
3595 * - The loader implements vkCreate{PLATFORM}SurfaceKHR() and
3596 * vkDestroySurfaceKHR(). The ICD must be capable of working with
3597 * such loader-managed surfaces.
3599 * - Loader interface v2 differs from v1 in:
3600 * - The first ICD entrypoint called by the loader is
3601 * vk_icdNegotiateLoaderICDInterfaceVersion(). The ICD must
3602 * statically expose this entrypoint.
3604 * - Loader interface v3 differs from v2 in:
3605 * - The ICD must implement vkCreate{PLATFORM}SurfaceKHR(),
3606 * vkDestroySurfaceKHR(), and other API which uses VKSurfaceKHR,
3607 * because the loader no longer does so.
