Description

This extension allows the depth clipping operation, that is normally implicitly controlled by VkPipelineRasterizationStateCreateInfo::depthClampEnable, to instead be controlled explicitly by VkPipelineRasterizationDepthClipStateCreateInfoEXT::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).

New Structures
