  -- == Description
  --
  -- This extension allows a shader resolve to replace fixed-function
  -- resolve.
  --
  -- Fixed-function resolve is limited in function to simple filters of
  -- multisample buffers to a single sample buffer.
  --
  -- Fixed-function resolve is more performance efficient and\/or power
  -- efficient than shader resolve for such simple filters.
  --
  -- Shader resolve allows a shader writer to create complex, non-linear
  -- filtering of a multisample buffer in the last subpass of a subpass
  -- dependency chain.
  --
  -- This extension also provides a bit which /can/ be used to enlarge a
  -- sample region dependency to a fragment region dependency, so that a
  -- framebuffer-region dependency /can/ replace a framebuffer-global
  -- dependency in some cases.
  --
  -- == New Enum Constants
  --
  -- -   'QCOM_RENDER_PASS_SHADER_RESOLVE_EXTENSION_NAME'
  --
  -- -   'QCOM_RENDER_PASS_SHADER_RESOLVE_SPEC_VERSION'
  --
  -- -   Extending
  --     'Vulkan.Core10.Enums.SubpassDescriptionFlagBits.SubpassDescriptionFlagBits':
  --
  --     -   'Vulkan.Core10.Enums.SubpassDescriptionFlagBits.SUBPASS_DESCRIPTION_FRAGMENT_REGION_BIT_QCOM'
  --
  --     -   'Vulkan.Core10.Enums.SubpassDescriptionFlagBits.SUBPASS_DESCRIPTION_SHADER_RESOLVE_BIT_QCOM'
  --
  -- == Issues
  --
  -- 1) Should this extension be named render_pass_shader_resolve?
  --
  -- __RESOLVED__ Yes.
  --
  -- This is part of suite of small extensions to render pass.
  --
  -- Following the style guide, instead of following
  -- VK_KHR_create_renderpass2.
  --
  -- 2) Should the VK_SAMPLE_COUNT_1_BIT be required for each
  -- pColorAttachment and the DepthStencilAttachent?
  --
  -- __RESOLVED__ No.
  --
  -- While this may not be a common use case, and while most fixed-function
  -- resolve hardware has this limitation, there is little reason to require
  -- a shader resolve to resolve to a single sample buffer.
  --
  -- 3) Should a shader resolve subpass be the last subpass in a render pass?
  --
  -- __RESOLVED__ Yes.
  --
  -- To be more specific, it should be the last subpass in a subpass
  -- dependency chain.
  --
  -- 4) Do we need the
  -- 'Vulkan.Core10.Enums.SubpassDescriptionFlagBits.SUBPASS_DESCRIPTION_FRAGMENT_REGION_BIT_QCOM'
  -- bit?
  --
  -- __RESOLVED__ Yes.
  --
  -- This applies when an input attachment’s sample count is equal to
  -- @rasterizationSamples@. Further, if @sampleShading@ is enabled
  -- (explicitly or implicitly) then @minSampleShading@ /must/ equal 0.0.
  --
  -- However, this bit may be set on any subpass, it is not restricted to a
  -- shader resolve subpass.
