  -- == Description
  --
  -- This extension adds support for the

  -- extension, allowing shaders to explicitly opt in to allowing both early
  -- /and/ late fragment tests with the @EarlyAndLateFragmentTestsAMD@
  -- execution mode.
  --
  -- If @VK_EXT_shader_stencil_export@ is supported, additional execution
  -- modes allowing early depth tests similar to @DepthUnchanged@,
  -- @DepthLess@, and @DepthGreater@ are provided.
