--
-- == Description
--
-- This extension allows the depth clipping operation, that is normally
-- implicitly controlled by
-- 'Vulkan.Core10.Pipeline.PipelineRasterizationStateCreateInfo'::@depthClampEnable@,
-- to instead be controlled explicitly by
-- 'PipelineRasterizationDepthClipStateCreateInfoEXT'::@depthClipEnable@.
--
-- This is useful for translating DX content which assumes depth clamping
-- is always enabled, but depth clip can be controlled by the
-- DepthClipEnable rasterization state (D3D12_RASTERIZER_DESC).
