  -- == Description
  --
  -- This extension adds Vulkan support for the
  -- <https://htmlpreview.github.io/?https://github.com/KhronosGroup/SPIRV-Registry/blob/master/extensions/EXT/SPV_EXT_demote_to_helper_invocation.html SPV_EXT_demote_to_helper_invocation>
  -- SPIR-V extension. That SPIR-V extension provides a new instruction
  -- @OpDemoteToHelperInvocationEXT@ allowing shaders to “demote” a fragment
  -- shader invocation to behave like a helper invocation for its duration.
  -- The demoted invocation will have no further side effects and will not
  -- output to the framebuffer, but remains active and can participate in
  -- computing derivatives and in
  -- <https://registry.khronos.org/vulkan/specs/1.3-extensions/html/vkspec.html#shaders-group-operations group operations>.
  -- This is a better match for the “discard” instruction in HLSL.

  -- == New Structures
  --
  -- -   Extending
  --     'Vulkan.Core11.Promoted_From_VK_KHR_get_physical_device_properties2.PhysicalDeviceFeatures2',
  --     'Vulkan.Core10.Device.DeviceCreateInfo':
  --
  --     -   'PhysicalDeviceShaderDemoteToHelperInvocationFeaturesEXT'
  --
  -- == New Enum Constants
  --
  -- -   'EXT_SHADER_DEMOTE_TO_HELPER_INVOCATION_EXTENSION_NAME'
  --
  -- -   'EXT_SHADER_DEMOTE_TO_HELPER_INVOCATION_SPEC_VERSION'
  --
  -- -   Extending 'Vulkan.Core10.Enums.StructureType.StructureType':
  --
  --     -   'STRUCTURE_TYPE_PHYSICAL_DEVICE_SHADER_DEMOTE_TO_HELPER_INVOCATION_FEATURES_EXT'
  --
  -- == New SPIR-V Capability
  --
  -- -   <https://registry.khronos.org/vulkan/specs/1.3-extensions/html/vkspec.html#spirvenv-capabilities-table-DemoteToHelperInvocationEXT DemoteToHelperInvocationEXT>
  --
  -- == Promotion to Vulkan 1.3
  --
  -- Functionality in this extension is included in core Vulkan 1.3, with the
  -- EXT suffix omitted. The original type, enum and command names are still
  -- available as aliases of the core functionality.
