4187 * - Loader interface v0 is incompatible with later versions. We don't
4190 * - In loader interface v1:
4191 * - The first ICD entrypoint called by the loader is
4192 * vk_icdGetInstanceProcAddr(). The ICD must statically expose this
4194 * - The ICD must statically expose no other Vulkan symbol unless it is
4195 * linked with -Bsymbolic.
4196 * - Each dispatchable Vulkan handle created by the ICD must be
4197 * a pointer to a struct whose first member is VK_LOADER_DATA. The
4198 * ICD must initialize VK_LOADER_DATA.loadMagic to ICD_LOADER_MAGIC.
4199 * - The loader implements vkCreate{PLATFORM}SurfaceKHR() and
4200 * vkDestroySurfaceKHR(). The ICD must be capable of working with
4201 * such loader-managed surfaces.
4203 * - Loader interface v2 differs from v1 in:
4204 * - The first ICD entrypoint called by the loader is
4205 * vk_icdNegotiateLoaderICDInterfaceVersion(). The ICD must
4206 * statically expose this entrypoint.
4208 * - Loader interface v3 differs from v2 in:
4209 * - The ICD must implement vkCreate{PLATFORM}SurfaceKHR(),
4210 * vkDestroySurfaceKHR(), and other API which uses VKSurfaceKHR,
4211 * because the loader no longer does so.
4213 * - Loader interface v4 differs from v3 in:
4214 * - The ICD must implement vk_icdGetPhysicalDeviceProcAddr().
