2044 * confusing official doc.
2046 * - Loader interface v0 is incompatible with later versions. We don't
2049 * - In loader interface v1:
2050 * - The first ICD entrypoint called by the loader is
2051 * vk_icdGetInstanceProcAddr(). The ICD must statically expose this
2053 * - The ICD must statically expose no other Vulkan symbol unless it is
2054 * linked with -Bsymbolic.
2055 * - Each dispatchable Vulkan handle created by the ICD must be
2056 * a pointer to a struct whose first member is VK_LOADER_DATA. The
2057 * ICD must initialize VK_LOADER_DATA.loadMagic to ICD_LOADER_MAGIC.
2058 * - The loader implements vkCreate{PLATFORM}SurfaceKHR() and
2059 * vkDestroySurfaceKHR(). The ICD must be capable of working with
2060 * such loader-managed surfaces.
2062 * - Loader interface v2 differs from v1 in:
2063 * - The first ICD entrypoint called by the loader is
2064 * vk_icdNegotiateLoaderICDInterfaceVersion(). The ICD must
2065 * statically expose this entrypoint.
2067 * - Loader interface v3 differs from v2 in:
2068 * - The ICD must implement vkCreate{PLATFORM}SurfaceKHR(),
2069 * vkDestroySurfaceKHR(), and other API which uses VKSurfaceKHR,
2070 * because the loader no longer does so.
