  -- == Description
  --
  -- This extension adds support for the following SPIR-V extension in
  -- Vulkan:
  --
  -- -   @SPV_KHR_post_depth_coverage@
  --
  -- which allows the fragment shader to control whether values in the
  -- 'Vulkan.Core10.FundamentalTypes.SampleMask' built-in input variable
  -- reflect the coverage after early
  -- <https://registry.khronos.org/vulkan/specs/1.3-extensions/html/vkspec.html#fragops-depth depth>
  -- and
  -- <https://registry.khronos.org/vulkan/specs/1.3-extensions/html/vkspec.html#fragops-stencil stencil>
  -- tests are applied.
  --
  -- This extension adds a new @PostDepthCoverage@ execution mode under the
  -- @SampleMaskPostDepthCoverage@ capability. When this mode is specified
  -- along with @EarlyFragmentTests@, the value of an input variable
  -- decorated with the
  -- <https://registry.khronos.org/vulkan/specs/1.3-extensions/html/vkspec.html#interfaces-builtin-variables-samplemask >
  -- built-in reflects the coverage after the early fragment tests are
  -- applied. Otherwise, it reflects the coverage before the depth and
  -- stencil tests.
  --
  -- When using GLSL source-based shading languages, the
  -- @post_depth_coverage@ layout qualifier from GL_ARB_post_depth_coverage
  -- or GL_EXT_post_depth_coverage maps to the @PostDepthCoverage@ execution
  -- mode.
