  -- == Description
  --
  -- This extension defines the 'FORMAT_A4R4G4B4_UNORM_PACK16_EXT' and
  -- 'FORMAT_A4B4G4R4_UNORM_PACK16_EXT' formats which are defined in other
  -- current graphics APIs.
  --
  -- This extension may be useful for building translation layers for those
  -- APIs or for porting applications that use these formats without having
  -- to resort to swizzles.
  --
  -- When VK_EXT_custom_border_color is used, these formats are not subject
  -- to the same restrictions for border color without format as with
  -- VK_FORMAT_B4G4R4A4_UNORM_PACK16.
  --
  -- == New Structures
  --
  -- -   Extending
  --     'Vulkan.Core11.Promoted_From_VK_KHR_get_physical_device_properties2.PhysicalDeviceFeatures2',
  --     'Vulkan.Core10.Device.DeviceCreateInfo':
  --
  --     -   'PhysicalDevice4444FormatsFeaturesEXT'
  --
  -- == New Enum Constants
  --
  -- -   'EXT_4444_FORMATS_EXTENSION_NAME'
  --
  -- -   'EXT_4444_FORMATS_SPEC_VERSION'
  --
  -- -   Extending 'Vulkan.Core10.Enums.Format.Format':
  --
  --     -   'FORMAT_A4B4G4R4_UNORM_PACK16_EXT'
  --
  --     -   'FORMAT_A4R4G4B4_UNORM_PACK16_EXT'
  --
  -- -   Extending 'Vulkan.Core10.Enums.StructureType.StructureType':
  --
  --     -   'Vulkan.Core10.Enums.StructureType.STRUCTURE_TYPE_PHYSICAL_DEVICE_4444_FORMATS_FEATURES_EXT'
  --
  -- == Promotion to Vulkan 1.3
  --
  -- This extension has been partially promoted. The format enumerants
  -- introduced by the extension are included in core Vulkan 1.3, with the
  -- EXT suffix omitted. However, runtime support for these formats is
  -- optional in core Vulkan 1.3, while if this extension is supported,
  -- runtime support is mandatory. The feature structure is not promoted. The
  -- original enum names are still available as aliases of the core
  -- functionality.

  -- = Description
  --
  -- If the 'PhysicalDevice4444FormatsFeaturesEXT' structure is included in
  -- the @pNext@ chain of the
  -- 'Vulkan.Core11.Promoted_From_VK_KHR_get_physical_device_properties2.PhysicalDeviceFeatures2'

  -- Note
  --
  -- Although the formats defined by the @VK_EXT_4444_formats@ extension were
