  -- == Description
  --
  -- This extension allows fragment shader invocations to read color, depth
  -- and stencil values at their pixel location in rasterization order. The
  -- functionality is only available when using dynamic render passes
  -- introduced by VK_KHR_dynamic_rendering. Example use cases are
  -- programmable blending and deferred shading.
  --
  -- See
  -- <https://registry.khronos.org/vulkan/specs/1.3-extensions/html/vkspec.html#fragops-shader-tileimage-reads fragment shader tile image reads>
  -- for more information.
