2112 * confusing official doc.
2114 * - Loader interface v0 is incompatible with later versions. We don't
2117 * - In loader interface v1:
2118 * - The first ICD entrypoint called by the loader is
2119 * vk_icdGetInstanceProcAddr(). The ICD must statically expose this
2121 * - The ICD must statically expose no other Vulkan symbol unless it is
2122 * linked with -Bsymbolic.
2123 * - Each dispatchable Vulkan handle created by the ICD must be
2124 * a pointer to a struct whose first member is VK_LOADER_DATA. The
2125 * ICD must initialize VK_LOADER_DATA.loadMagic to ICD_LOADER_MAGIC.
2126 * - The loader implements vkCreate{PLATFORM}SurfaceKHR() and
2127 * vkDestroySurfaceKHR(). The ICD must be capable of working with
2128 * such loader-managed surfaces.
2130 * - Loader interface v2 differs from v1 in:
2131 * - The first ICD entrypoint called by the loader is
2132 * vk_icdNegotiateLoaderICDInterfaceVersion(). The ICD must
2133 * statically expose this entrypoint.
2135 * - Loader interface v3 differs from v2 in:
2136 * - The ICD must implement vkCreate{PLATFORM}SurfaceKHR(),
2137 * vkDestroySurfaceKHR(), and other API which uses VKSurfaceKHR,
2138 * because the loader no longer does so.
