--
-- == Description
--
-- This extension adds the ability to change the rate at which fragments
-- are shaded. Rather than the usual single fragment invocation for each
-- pixel covered by a primitive, multiple pixels can be shaded by a single
-- fragment shader invocation.
--
-- Up to three methods are available to the application to change the
-- fragment shading rate:
--
-- -   <https://www.khronos.org/registry/vulkan/specs/1.2-extensions/html/vkspec.html#primsrast-fragment-shading-rate-pipeline>,
--     which allows the specification of a rate per-draw.
--
-- -   <https://www.khronos.org/registry/vulkan/specs/1.2-extensions/html/vkspec.html#primsrast-fragment-shading-rate-primitive>,
--     which allows the specification of a rate per primitive, specified
--     during shading.
--
-- -   <https://www.khronos.org/registry/vulkan/specs/1.2-extensions/html/vkspec.html#primsrast-fragment-shading-rate-attachment>,
--     which allows the specification of a rate per-region of the
--     framebuffer, specified in a specialized image attachment.
--
-- Additionally, these rates can all be specified and combined in order to
-- adjust the overall detail in the image at each point.
--
-- This functionality can be used to focus shading efforts where higher
-- levels of detail are needed in some parts of a scene compared to others.
-- This can be particularly useful in high resolution rendering, or for XR
-- contexts.
--
-- This extension also adds support for the @SPV_KHR_fragment_shading_rate@
-- extension which enables setting the
-- <https://www.khronos.org/registry/vulkan/specs/1.2-extensions/html/vkspec.html#primsrast-fragment-shading-rate-primitive primitive fragment shading rate>,
-- and allows querying the final shading rate from a fragment shader.
