  -- == Description
  --
  -- This extension adds more expressive alignment requirements for uniform
  -- and storage texel buffers. Some implementations have single texel
  -- alignment requirements that cannot be expressed via
  -- 'Vulkan.Core10.DeviceInitialization.PhysicalDeviceLimits'::@minTexelBufferOffsetAlignment@.
  --
  -- == New Structures
  --
  -- -   Extending
  --     'Vulkan.Core11.Promoted_From_VK_KHR_get_physical_device_properties2.PhysicalDeviceFeatures2',
  --     'Vulkan.Core10.Device.DeviceCreateInfo':
  --
  --     -   'PhysicalDeviceTexelBufferAlignmentFeaturesEXT'
  --
  -- -   Extending
  --     'Vulkan.Core11.Promoted_From_VK_KHR_get_physical_device_properties2.PhysicalDeviceProperties2':
  --
  --     -   'PhysicalDeviceTexelBufferAlignmentPropertiesEXT'
  --
  -- == New Enum Constants
  --
  -- -   'EXT_TEXEL_BUFFER_ALIGNMENT_EXTENSION_NAME'
  --
  -- -   'EXT_TEXEL_BUFFER_ALIGNMENT_SPEC_VERSION'
  --
  -- -   Extending 'Vulkan.Core10.Enums.StructureType.StructureType':
  --
  --     -   'Vulkan.Core10.Enums.StructureType.STRUCTURE_TYPE_PHYSICAL_DEVICE_TEXEL_BUFFER_ALIGNMENT_FEATURES_EXT'
  --
  --     -   'STRUCTURE_TYPE_PHYSICAL_DEVICE_TEXEL_BUFFER_ALIGNMENT_PROPERTIES_EXT'
  --
  -- == Promotion to Vulkan 1.3
  --
  -- Functionality in this extension is included in core Vulkan 1.3, with the
  -- EXT suffix omitted. However, only the properties structure is promoted.
  -- The feature structure is not promoted and @texelBufferAlignment@ is
  -- enabled if using a Vulkan 1.3 instance. The original type name is still
  -- available as an alias of the core functionality.
  --
  -- == Version History
