-- == Description
--
-- Renderpasses, and specifically
-- <https://www.khronos.org/registry/vulkan/specs/1.2-extensions/html/vkspec.html#synchronization-pipeline-barriers-subpass-self-dependencies subpass self-dependencies>
-- enable much of the same functionality as the framebuffer fetch and pixel
-- local storage extensions did for OpenGL ES. But certain techniques such
-- as programmable blending are awkward or impractical to implement with
-- these alone, in part because a self-dependency is required every time a
-- fragment will read a value at a given sample coordinate.
--
-- This extension extends the mechanism of input attachments to allow
-- access to framebuffer attachments when used as both input and color, or
-- depth\/stencil, attachments from one fragment to the next, in
-- rasterization order, without explicit synchronization.
--
-- See
-- <https://www.khronos.org/registry/vulkan/specs/1.2-extensions/html/vkspec.html#renderpass-feedbackloop renderpass feedback loops>
-- for more information.

--
-- == Issues
--
-- 1) Is there any interaction with the @VK_KHR_dynamic_rendering@
-- extension?
--
-- No. This extension only affects reads from input attachments. Render
-- pass instances begun with
-- 'Vulkan.Extensions.VK_KHR_dynamic_rendering.cmdBeginRenderingKHR' do not
-- have input attachments and a different mechanism will be needed to
-- provide similar functionality in this case.
--
-- == Examples
--
-- None.
