-- == 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://www.khronos.org/registry/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://www.khronos.org/registry/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.
