  -- == Description
  --
  -- This extension adds the 'QueryLowLatencySupportNV' structure, a
  -- structure used to query support for NVIDIA Reflex.
  --
  -- == New Structures
  --
  -- -   Extending 'Vulkan.Core10.QueueSemaphore.SemaphoreCreateInfo':
  --
  --     -   'QueryLowLatencySupportNV'
  --
  -- == New Enum Constants
  --
  -- -   'NV_LOW_LATENCY_EXTENSION_NAME'
  --
  -- -   'NV_LOW_LATENCY_SPEC_VERSION'
  --
  -- -   Extending 'Vulkan.Core10.Enums.StructureType.StructureType':
  --
  --     -   'Vulkan.Core10.Enums.StructureType.STRUCTURE_TYPE_QUERY_LOW_LATENCY_SUPPORT_NV'
  --
  -- == Issues
  --
  -- 1) Why does 'QueryLowLatencySupportNV' have output parameters in an
  -- input chain?
  --
  -- __RESOLVED__: We are stuck with this for legacy reasons - we are aware
  -- this is bad behavior and this should not be used as a precedent for
  -- future extensions.
