-- = Description
--
-- The scissor rectangles taken from element i of @pExclusiveScissors@
-- replace the current state for the scissor index @firstExclusiveScissor@
-- + i, for i in [0, @exclusiveScissorCount@).

-- This command sets the state for a given draw when the graphics pipeline
-- is created with

-- set in
-- 'Vulkan.Core10.Pipeline.PipelineDynamicStateCreateInfo'::@pDynamicStates@.

--     overflow
--
-- -   Evaluation of (@offset.y@ + @extent.height@) for each member of

-- | VkPipelineViewportExclusiveScissorStateCreateInfoNV - Structure
-- specifying parameters controlling exclusive scissor testing
--
-- = Description
--
-- If the
-- 'Vulkan.Core10.Enums.DynamicState.DYNAMIC_STATE_EXCLUSIVE_SCISSOR_NV'
-- dynamic state is enabled for a pipeline, the @pExclusiveScissors@ member
-- is ignored.
--
-- When this structure is included in the @pNext@ chain of
-- 'Vulkan.Core10.Pipeline.GraphicsPipelineCreateInfo', it defines
-- parameters of the exclusive scissor test. If this structure is not
-- included in the @pNext@ chain, it is equivalent to specifying this
-- structure with a @exclusiveScissorCount@ of @0@.
--
-- == Valid Usage
--
-- -   If the
--     <https://www.khronos.org/registry/vulkan/specs/1.2-extensions/html/vkspec.html#features-multiViewport multiple viewports>
--     feature is not enabled, @exclusiveScissorCount@ /must/ be @0@ or @1@
--
-- -   @exclusiveScissorCount@ /must/ be less than or equal to
--     'Vulkan.Core10.DeviceInitialization.PhysicalDeviceLimits'::@maxViewports@
--
-- -   @exclusiveScissorCount@ /must/ be @0@ or identical to the
--     @viewportCount@ member of
--     'Vulkan.Core10.Pipeline.PipelineViewportStateCreateInfo'
--
-- -   If no element of the @pDynamicStates@ member of @pDynamicState@ is
--     'Vulkan.Core10.Enums.DynamicState.DYNAMIC_STATE_EXCLUSIVE_SCISSOR_NV'
--     and @exclusiveScissorCount@ is not @0@, @pExclusiveScissors@ /must/
--     be a valid pointer to an array of @exclusiveScissorCount@
--     'Vulkan.Core10.CommandBufferBuilding.Rect2D' structures
--
-- == Valid Usage (Implicit)
--
-- -   @sType@ /must/ be
--     'Vulkan.Core10.Enums.StructureType.STRUCTURE_TYPE_PIPELINE_VIEWPORT_EXCLUSIVE_SCISSOR_STATE_CREATE_INFO_NV'
--
-- -   If @exclusiveScissorCount@ is not @0@, and @pExclusiveScissors@ is
--     not @NULL@, @pExclusiveScissors@ /must/ be a valid pointer to an
--     array of @exclusiveScissorCount@
