  --
  -- == Description
  --
  -- This extension enables the
  -- 'Vulkan.Core10.Enums.Format.FORMAT_R10X6G10X6B10X6A10X6_UNORM_4PACK16'
  -- format to be used without a
  -- <https://registry.khronos.org/vulkan/specs/1.3-extensions/html/vkspec.html#samplers-YCbCr-conversion sampler Y′CBCR conversion>
  -- enabled.
  --
  -- == New Structures
  --
  -- -   Extending
  --     'Vulkan.Core11.Promoted_From_VK_KHR_get_physical_device_properties2.PhysicalDeviceFeatures2',
  --     'Vulkan.Core10.Device.DeviceCreateInfo':
  --
  --     -   'PhysicalDeviceRGBA10X6FormatsFeaturesEXT'
  --
  -- == New Enum Constants
  --
  -- -   'EXT_RGBA10X6_FORMATS_EXTENSION_NAME'
  --
  -- -   'EXT_RGBA10X6_FORMATS_SPEC_VERSION'
  --
  -- -   Extending 'Vulkan.Core10.Enums.StructureType.StructureType':
  --
  --     -   'Vulkan.Core10.Enums.StructureType.STRUCTURE_TYPE_PHYSICAL_DEVICE_RGBA10X6_FORMATS_FEATURES_EXT'
  --
  -- == Issues
  --
  -- 1) Should we reuse the existing format enumeration or introduce a new
  -- one?
  --
  -- __RESOLVED__: We reuse an existing format enumeration,
  -- 'Vulkan.Core10.Enums.Format.FORMAT_R10X6G10X6B10X6A10X6_UNORM_4PACK16',
  -- that was previously exclusively used for YCbCr and therefore had a set
  -- of limitations related to that usage. The alternative was to introduce a
  -- new format token with exactly the same bit representation as the
  -- existing token, but without the limitations.
  --
  -- 2) Should we only introduce
  -- 'Vulkan.Core10.Enums.Format.FORMAT_R10X6G10X6B10X6A10X6_UNORM_4PACK16'
  -- or also 1-3 component variations?
  --
  -- __RESOLVED__: Only the 4-component format is introduced because the 1-
  -- and 2- component variations are already not exclusive to YCbCr, and the
  -- 3-component variation is not a good match for hardware capabilities.
