-- == Description
--
-- This extension adds some Y′CBCR formats that are in common use for video
-- encode and decode, but were not part of the
-- @VK_KHR_sampler_ycbcr_conversion@ extension.
--
-- == New Structures
--
-- -   Extending
--     'Vulkan.Core11.Promoted_From_VK_KHR_get_physical_device_properties2.PhysicalDeviceFeatures2',
--     'Vulkan.Core10.Device.DeviceCreateInfo':
--
--     -   'PhysicalDeviceYcbcr2Plane444FormatsFeaturesEXT'
--
-- == New Enum Constants
--
-- -   'EXT_YCBCR_2PLANE_444_FORMATS_EXTENSION_NAME'
--
-- -   'EXT_YCBCR_2PLANE_444_FORMATS_SPEC_VERSION'
--
-- -   Extending 'Vulkan.Core10.Enums.Format.Format':
