--
-- == 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/1.3-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/1.3-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/1.3-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/1.3-extensions/html/vkspec.html#primsrast-fragment-shading-rate-primitive primitive fragment shading rate>,
-- and allows querying the final shading rate from a fragment shader.

-- | vkCmdSetFragmentShadingRateKHR - Set pipeline fragment shading rate and
-- combiner operation dynamically for a command buffer
--
-- = Description
--
-- This command sets the pipeline fragment shading rate and combiner
-- operation for subsequent drawing commands when the graphics pipeline is
-- created with
-- 'Vulkan.Core10.Enums.DynamicState.DYNAMIC_STATE_FRAGMENT_SHADING_RATE_KHR'
-- set in
-- 'Vulkan.Core10.Pipeline.PipelineDynamicStateCreateInfo'::@pDynamicStates@.
-- Otherwise, this state is specified by the
-- 'PipelineFragmentShadingRateStateCreateInfoKHR' values used to create
-- the currently active pipeline.

-- for a physical device
--
-- = Description
--
-- If @pFragmentShadingRates@ is @NULL@, then the number of fragment
-- shading rates available is returned in @pFragmentShadingRateCount@.
-- Otherwise, @pFragmentShadingRateCount@ /must/ point to a variable set by
-- the user to the number of elements in the @pFragmentShadingRates@ array,
-- and on return the variable is overwritten with the number of structures
-- actually written to @pFragmentShadingRates@. If
-- @pFragmentShadingRateCount@ is less than the number of fragment shading
-- rates available, at most @pFragmentShadingRateCount@ structures will be
-- written, and 'Vulkan.Core10.Enums.Result.INCOMPLETE' will be returned
-- instead of 'Vulkan.Core10.Enums.Result.SUCCESS', to indicate that not
-- all the available fragment shading rates were returned.
--
-- The returned array of fragment shading rates /must/ be ordered from
-- largest @fragmentSize.width@ value to smallest, and each set of fragment
-- shading rates with the same @fragmentSize.width@ value /must/ be ordered
-- from largest @fragmentSize.height@ to smallest. Any two entries in the
-- array /must/ not have the same @fragmentSize@ values.
--
-- For any entry in the array, the following rules also apply:
--
-- -   The value of @fragmentSize.width@ /must/ be less than or equal to
--     <https://www.khronos.org/registry/vulkan/specs/1.3-extensions/html/vkspec.html#limits-maxFragmentSize maxFragmentSize.width>.
--
-- -   The value of @fragmentSize.width@ /must/ be greater than or equal to
--     @1@.
--
-- -   The value of @fragmentSize.width@ /must/ be a power-of-two.
--
-- -   The value of @fragmentSize.height@ /must/ be less than or equal to
--     <https://www.khronos.org/registry/vulkan/specs/1.3-extensions/html/vkspec.html#limits-maxFragmentSize maxFragmentSize.height>.
--
-- -   The value of @fragmentSize.height@ /must/ be greater than or equal
--     to @1@.
--
-- -   The value of @fragmentSize.height@ /must/ be a power-of-two.
--
-- -   The highest sample count in @sampleCounts@ /must/ be less than or
--     equal to
--     <https://www.khronos.org/registry/vulkan/specs/1.3-extensions/html/vkspec.html#limits-maxFragmentShadingRateRasterizationSamples maxFragmentShadingRateRasterizationSamples>.
--
-- -   The product of @fragmentSize.width@, @fragmentSize.height@, and the
--     highest sample count in @sampleCounts@ /must/ be less than or equal
--     to
--     <https://www.khronos.org/registry/vulkan/specs/1.3-extensions/html/vkspec.html#limits-maxFragmentShadingRateCoverageSamples maxFragmentShadingRateCoverageSamples>.

-- includes 'Vulkan.Core10.Enums.SampleCountFlagBits.SAMPLE_COUNT_2_BIT',
-- the required rates /must/ also include
-- 'Vulkan.Core10.Enums.SampleCountFlagBits.SAMPLE_COUNT_2_BIT'.
--
-- Note
--
-- Including the {1,1} fragment size is done for completeness; it has no
-- actual effect on the support of rendering without setting the fragment
-- size. All sample counts and render pass transforms are supported for
-- this rate.
--
-- The returned set of fragment shading rates /must/ be returned in the
-- native (rotated) coordinate system. For rasterization using render pass
-- @transform@ not equal to
-- 'Vulkan.Extensions.VK_KHR_surface.SURFACE_TRANSFORM_IDENTITY_BIT_KHR',
-- the application /must/ transform the returned fragment shading rates
-- into the current (unrotated) coordinate system to get the supported
-- rates for that transform.
--
-- Note
--
-- For example, consider an implementation returning support for 4x2, but
-- not 2x4 in the set of supported fragment shading rates. This means that
-- for transforms
-- 'Vulkan.Extensions.VK_KHR_surface.SURFACE_TRANSFORM_ROTATE_90_BIT_KHR'
-- and
-- 'Vulkan.Extensions.VK_KHR_surface.SURFACE_TRANSFORM_ROTATE_270_BIT_KHR',
-- 2x4 is a supported rate, but 4x2 is an unsupported rate.

-- = Description
--
-- Note
--
-- Multiplication of the combiner rates using the fragment width\/height in
-- linear space is equivalent to an addition of those values in log2 space.
-- Some implementations inadvertently implemented an addition in linear
-- space due to unclear requirements originating outside of this
-- specification. This resulted in
-- <https://www.khronos.org/registry/vulkan/specs/1.3-extensions/html/vkspec.html#limits-fragmentShadingRateStrictMultiplyCombiner fragmentShadingRateStrictMultiplyCombiner>
-- being added. Fortunately, this only affects situations where a rate of 1
-- in either dimension is combined with another rate of 1. All other
-- combinations result in the exact same result as if multiplication was
-- performed in linear space due to the clamping logic, and the fact that
-- both the sum and product of 2 and 2 are equal. In many cases, this limit
-- will not affect the correct operation of applications.
--
-- If the 'PhysicalDeviceFragmentShadingRatePropertiesKHR' structure is
-- included in the @pNext@ chain of the
-- 'Vulkan.Core11.Promoted_From_VK_KHR_get_physical_device_properties2.PhysicalDeviceProperties2'
-- structure passed to
