-- == Description
--
-- This extension adds support for the @FragmentShaderPixelInterlockEXT@,
-- @FragmentShaderSampleInterlockEXT@, and
-- @FragmentShaderShadingRateInterlockEXT@ capabilities from the
-- @SPV_EXT_fragment_shader_interlock@ extension to Vulkan.
--
-- Enabling these capabilities provides a critical section for fragment
-- shaders to avoid overlapping pixels being processed at the same time,
-- and certain guarantees about the ordering of fragment shader invocations
-- of fragments of overlapping pixels.
--
-- This extension can be useful for algorithms that need to access
-- per-pixel data structures via shader loads and stores. Algorithms using
-- this extension can access per-pixel data structures in critical sections
-- without other invocations accessing the same per-pixel data.
-- Additionally, the ordering guarantees are useful for cases where the API
-- ordering of fragments is meaningful. For example, applications may be
-- able to execute programmable blending operations in the fragment shader,
-- where the destination buffer is read via image loads and the final value
-- is written via image stores.
