  -- == Description
  --
  -- @VK_IMG_format_pvrtc@ provides additional texture compression
  -- functionality specific to Imagination Technologies PowerVR Texture
  -- compression format (called PVRTC).
  --
  -- == Deprecation
  --
  -- Both PVRTC1 and PVRTC2 are slower than standard image formats on PowerVR
  -- GPUs, and support will be removed from future hardware.
