-- == Description
--
-- This extension allows applications to use a variable shading rate when
-- processing fragments of rasterized primitives. By default, Vulkan will
-- spawn one fragment shader for each pixel covered by a primitive. In this
-- extension, applications can bind a /shading rate image/ that can be used
-- to vary the number of fragment shader invocations across the
-- framebuffer. Some portions of the screen may be configured to spawn up
-- to 16 fragment shaders for each pixel, while other portions may use a
-- single fragment shader invocation for a 4x4 block of pixels. This can be
-- useful for use cases like eye tracking, where the portion of the
-- framebuffer that the user is looking at directly can be processed at
-- high frequency, while distant corners of the image can be processed at
-- lower frequency. Each texel in the shading rate image represents a
-- fixed-size rectangle in the framebuffer, covering 16x16 pixels in the
-- initial implementation of this extension. When rasterizing a primitive
-- covering one of these rectangles, the Vulkan implementation reads a
-- texel in the bound shading rate image and looks up the fetched value in
-- a palette to determine a base shading rate.
--
-- In addition to the API support controlling rasterization, this extension
-- also adds Vulkan support for the
-- <https://htmlpreview.github.io/?https://github.com/KhronosGroup/SPIRV-Registry/blob/master/extensions/NV/SPV_NV_shading_rate.html SPV_NV_shading_rate>
-- extension to SPIR-V. That extension provides two fragment shader
-- variable decorations that allow fragment shaders to determine the
-- shading rate used for processing the fragment:
--
-- -   @FragmentSizeNV@, which indicates the width and height of the set of
--     pixels processed by the fragment shader.
--
-- -   @InvocationsPerPixel@, which indicates the maximum number of
--     fragment shader invocations that could be spawned for the pixel(s)
--     covered by the fragment.
--
-- When using SPIR-V in conjunction with the OpenGL Shading Language
-- (GLSL), the fragment shader capabilities are provided by the
-- @GL_NV_shading_rate_image@ language extension and correspond to the
-- built-in variables @gl_FragmentSizeNV@ and @gl_InvocationsPerPixelNV@,
-- respectively.

--
-- == Issues
--
-- (1) When using shading rates specifying “coarse” fragments covering
-- multiple pixels, we will generate a combined coverage mask that combines
-- the coverage masks of all pixels covered by the fragment. By default,
-- these masks are combined in an implementation-dependent order. Should we
-- provide a mechanism allowing applications to query or specify an exact
-- order?
--
-- __RESOLVED__: Yes, this feature is useful for cases where most of the
-- fragment shader can be evaluated once for an entire coarse fragment, but
-- where some per-pixel computations are also required. For example, a
-- per-pixel alpha test may want to kill all the samples for some pixels in
-- a coarse fragment. This sort of test can be implemented using an output
-- sample mask, but such a shader would need to know which bit in the mask
-- corresponds to each sample in the coarse fragment. We are including a
-- mechanism to allow aplications to specify the orders of coverage samples
-- for each shading rate and sample count, either as static pipeline state
-- or dynamically via a command buffer. This portion of the extension has
-- its own feature bit.
--
-- We will not be providing a query to determine the
-- implementation-dependent default ordering. The thinking here is that if
-- an application cares enough about the coarse fragment sample ordering to
-- perform such a query, it could instead just set its own order, also
-- using custom per-pixel sample locations if required.
--
-- (2) For the pipeline stage 'PIPELINE_STAGE_SHADING_RATE_IMAGE_BIT_NV',
-- should we specify a precise location in the pipeline the shading rate
-- image is accessed (after geometry shading, but before the early fragment
-- tests) or leave it under-specified in case there are other
-- implementations that access the image in a different pipeline location?
--
-- __RESOLVED__ We are specifying the pipeline stage to be between the
-- final
-- <https://www.khronos.org/registry/vulkan/specs/1.2-extensions/html/vkspec.html#pipeline-graphics-subsets-pre-rasterization pre-rasterization shader stage>
-- ('Vulkan.Core10.Enums.PipelineStageFlagBits.PIPELINE_STAGE_GEOMETRY_SHADER_BIT')
-- and before the first stage used for fragment processing
-- ('Vulkan.Core10.Enums.PipelineStageFlagBits.PIPELINE_STAGE_EARLY_FRAGMENT_TESTS_BIT'),
-- which seems to be the natural place to access the shading rate image.
--
-- (3) How do centroid-sampled variables work with fragments larger than
-- one pixel?
--
-- __RESOLVED__ For single-pixel fragments, fragment shader inputs
-- decorated with @Centroid@ are sampled at an implementation-dependent
-- location in the intersection of the area of the primitive being
-- rasterized and the area of the pixel that corresponds to the fragment.
-- With multi-pixel fragments, we follow a similar pattern, using the
-- intersection of the primitive and the __set__ of pixels corresponding to
-- the fragment.
--
-- One important thing to keep in mind when using such “coarse” shading
-- rates is that fragment attributes are sampled at the center of the
-- fragment by default, regardless of the set of pixels\/samples covered by
-- the fragment. For fragments with a size of 4x4 pixels, this center
-- location will be more than two pixels (1.5 * sqrt(2)) away from the
-- center of the pixels at the corners of the fragment. When rendering a
-- primitive that covers only a small part of a coarse fragment, sampling a
-- color outside the primitive can produce overly bright or dark color
-- values if the color values have a large gradient. To deal with this, an
-- application can use centroid sampling on attributes where
-- “extrapolation” artifacts can lead to overly bright or dark pixels. Note
-- that this same problem also exists for multisampling with single-pixel
-- fragments, but is less severe because it only affects certain samples of
-- a pixel and such bright\/dark samples may be averaged with other samples
-- that do not have a similar problem.
