## 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

- Extending VkPhysicalDeviceFeatures2, VkDeviceCreateInfo:

  - VkPhysicalDeviceDepthClipEnableFeaturesEXT

- Extending VkPipelineRasterizationStateCreateInfo:

  - VkPipelineRasterizationDepthClipStateCreateInfoEXT

## New Bitmasks

- VkPipelineRasterizationDepthClipStateCreateFlagsEXT

## New Enum Constants

- `VK_EXT_DEPTH_CLIP_ENABLE_EXTENSION_NAME`

- `VK_EXT_DEPTH_CLIP_ENABLE_SPEC_VERSION`

- Extending VkStructureType:

  - `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_DEPTH_CLIP_ENABLE_FEATURES_EXT`

  - `VK_STRUCTURE_TYPE_PIPELINE_RASTERIZATION_DEPTH_CLIP_STATE_CREATE_INFO_EXT`

## Version History
