2678 * - Loader interface v0 is incompatible with later versions. We don't
2681 * - In loader interface v1:
2682 * - The first ICD entrypoint called by the loader is
2683 * vk_icdGetInstanceProcAddr(). The ICD must statically expose this
2685 * - The ICD must statically expose no other Vulkan symbol unless it is
2686 * linked with -Bsymbolic.
2687 * - Each dispatchable Vulkan handle created by the ICD must be
2688 * a pointer to a struct whose first member is VK_LOADER_DATA. The
2689 * ICD must initialize VK_LOADER_DATA.loadMagic to ICD_LOADER_MAGIC.
2690 * - The loader implements vkCreate{PLATFORM}SurfaceKHR() and
2691 * vkDestroySurfaceKHR(). The ICD must be capable of working with
2692 * such loader-managed surfaces.
2694 * - Loader interface v2 differs from v1 in:
2695 * - The first ICD entrypoint called by the loader is
2696 * vk_icdNegotiateLoaderICDInterfaceVersion(). The ICD must
2697 * statically expose this entrypoint.
2699 * - Loader interface v3 differs from v2 in:
2700 * - The ICD must implement vkCreate{PLATFORM}SurfaceKHR(),
2701 * vkDestroySurfaceKHR(), and other API which uses VKSurfaceKHR,
2702 * because the loader no longer does so.
