  -- == Description
  --
  -- This extension adds support for textures compressed using the Adaptive
  -- Scalable Texture Compression (ASTC) High Dynamic Range (HDR) profile.
  --
  -- When this extension is enabled, the HDR profile is supported for all
  -- ASTC formats listed in
  -- <https://registry.khronos.org/vulkan/specs/1.3-extensions/html/vkspec.html#appendix-compressedtex-astc ASTC Compressed Image Formats>.

  --
  -- == Promotion to Vulkan 1.3
  --
  -- This extension has been partially promoted. Functionality in this
  -- extension is included in core Vulkan 1.3, with the EXT suffix omitted.
  -- However, the feature is made optional in Vulkan 1.3. The original type,
  -- enum and command names are still available as aliases of the core
  -- functionality.
  --
  -- == Issues
  --
  -- 1) Should we add a feature or limit for this functionality?
  --
  -- Yes. It is consistent with the ASTC LDR support to add a feature like
  -- textureCompressionASTC_HDR.
  --
  -- The feature is strictly speaking redundant as long as this is just an
  -- extension; it would be sufficient to just enable the extension. But
  -- adding the feature is more forward-looking if wanted to make this an
  -- optional core feature in the future.
  --
  -- 2) Should we introduce new format enums for HDR?
  --
  -- Yes. Vulkan 1.0 describes the ASTC format enums as UNORM, e.g.
  -- 'Vulkan.Core10.Enums.Format.FORMAT_ASTC_4x4_UNORM_BLOCK', so it is
  -- confusing to make these contain HDR data. Note that the OpenGL (ES)
  -- extensions did not make this distinction because a single ASTC HDR
  -- texture may contain both unorm and float blocks. Implementations /may/
  -- not be able to distinguish between LDR and HDR ASTC textures internally
  -- and just treat them as the same format, i.e. if this extension is
  -- supported then sampling from a
  -- 'Vulkan.Core10.Enums.Format.FORMAT_ASTC_4x4_UNORM_BLOCK' image format
  -- /may/ return HDR results. Applications /can/ get predictable results by
  -- using the appropriate image format.
