Author: Chia-I Wu <[email protected]> Date: Tue Dec 19 14:06:16 2023 -0800 vk/util: ignore unsupported feature structs vk_physical_device_check_device_features should ignore unsupported feature structs: Any component of the implementation (the loader, any enabled layers, and drivers) must skip over, without processing (other than reading the sType and pNext members) any extending structures in the chain not defined by core versions or extensions supported by that component.
