-- = Description
--
-- If the attachment uses a color format, then @loadOp@ and @storeOp@ are
-- used, and @stencilLoadOp@ and @stencilStoreOp@ are ignored. If the
-- format has depth and\/or stencil components, @loadOp@ and @storeOp@
-- apply only to the depth data, while @stencilLoadOp@ and @stencilStoreOp@
-- define how the stencil data is handled. @loadOp@ and @stencilLoadOp@
-- define the /load operations/ that execute as part of the first subpass
-- that uses the attachment. @storeOp@ and @stencilStoreOp@ define the
-- /store operations/ that execute as part of the last subpass that uses
-- the attachment.
--
-- The load operation for each sample in an attachment happens-before any
-- recorded command which accesses the sample in the first subpass where
-- the attachment is used. Load operations for attachments with a
-- depth\/stencil format execute in the
-- 'Vulkan.Core10.Enums.PipelineStageFlagBits.PIPELINE_STAGE_EARLY_FRAGMENT_TESTS_BIT'
-- pipeline stage. Load operations for attachments with a color format
-- execute in the
-- 'Vulkan.Core10.Enums.PipelineStageFlagBits.PIPELINE_STAGE_COLOR_ATTACHMENT_OUTPUT_BIT'
-- pipeline stage.
--
-- The store operation for each sample in an attachment happens-after any
-- recorded command which accesses the sample in the last subpass where the
-- attachment is used. Store operations for attachments with a
-- depth\/stencil format execute in the
-- 'Vulkan.Core10.Enums.PipelineStageFlagBits.PIPELINE_STAGE_LATE_FRAGMENT_TESTS_BIT'
-- pipeline stage. Store operations for attachments with a color format
-- execute in the
-- 'Vulkan.Core10.Enums.PipelineStageFlagBits.PIPELINE_STAGE_COLOR_ATTACHMENT_OUTPUT_BIT'
-- pipeline stage.
--
-- If an attachment is not used by any subpass, then @loadOp@, @storeOp@,
-- @stencilStoreOp@, and @stencilLoadOp@ are ignored, and the attachment’s
-- memory contents will not be modified by execution of a render pass
-- instance.
--
-- The load and store operations apply on the first and last use of each
-- view in the render pass, respectively. If a view index of an attachment
-- is not included in the view mask in any subpass that uses it, then the
-- load and store operations are ignored, and the attachment’s memory
-- contents will not be modified by execution of a render pass instance.
--
-- During a render pass instance, input\/color attachments with color
-- formats that have a component size of 8, 16, or 32 bits /must/ be
-- represented in the attachment’s format throughout the instance.
-- Attachments with other floating- or fixed-point color formats, or with
-- depth components /may/ be represented in a format with a precision
-- higher than the attachment format, but /must/ be represented with the
-- same range. When such a component is loaded via the @loadOp@, it will be
-- converted into an implementation-dependent format used by the render
-- pass. Such components /must/ be converted from the render pass format,
-- to the format of the attachment, before they are resolved or stored at
-- the end of a render pass instance via @storeOp@. Conversions occur as
-- described in
-- <https://www.khronos.org/registry/vulkan/specs/1.2-extensions/html/vkspec.html#fundamentals-numerics Numeric Representation and Computation>
-- and
-- <https://www.khronos.org/registry/vulkan/specs/1.2-extensions/html/vkspec.html#fundamentals-fixedconv Fixed-Point Data Conversions>.
--
-- If @flags@ includes
-- 'Vulkan.Core10.Enums.AttachmentDescriptionFlagBits.ATTACHMENT_DESCRIPTION_MAY_ALIAS_BIT',
-- then the attachment is treated as if it shares physical memory with
-- another attachment in the same render pass. This information limits the
-- ability of the implementation to reorder certain operations (like layout
-- transitions and the @loadOp@) such that it is not improperly reordered
-- against other uses of the same physical memory via a different
-- attachment. This is described in more detail below.
--
-- If a render pass uses multiple attachments that alias the same device
-- memory, those attachments /must/ each include the
-- 'Vulkan.Core10.Enums.AttachmentDescriptionFlagBits.ATTACHMENT_DESCRIPTION_MAY_ALIAS_BIT'
-- bit in their attachment description flags. Attachments aliasing the same
-- memory occurs in multiple ways:
--
-- -   Multiple attachments being assigned the same image view as part of
--     framebuffer creation.
--
-- -   Attachments using distinct image views that correspond to the same
--     image subresource of an image.
--
-- -   Attachments using views of distinct image subresources which are
--     bound to overlapping memory ranges.
--
-- Note
--
-- Render passes /must/ include subpass dependencies (either directly or
-- via a subpass dependency chain) between any two subpasses that operate
-- on the same attachment or aliasing attachments and those subpass
-- dependencies /must/ include execution and memory dependencies separating
-- uses of the aliases, if at least one of those subpasses writes to one of
-- the aliases. These dependencies /must/ not include the
-- 'Vulkan.Core10.Enums.DependencyFlagBits.DEPENDENCY_BY_REGION_BIT' if the
-- aliases are views of distinct image subresources which overlap in
-- memory.
--
-- Multiple attachments that alias the same memory /must/ not be used in a
-- single subpass. A given attachment index /must/ not be used multiple
-- times in a single subpass, with one exception: two subpass attachments
-- /can/ use the same attachment index if at least one use is as an input
-- attachment and neither use is as a resolve or preserve attachment. In
-- other words, the same view /can/ be used simultaneously as an input and
-- color or depth\/stencil attachment, but /must/ not be used as multiple
-- color or depth\/stencil attachments nor as resolve or preserve
-- attachments. The precise set of valid scenarios is described in more
-- detail
-- <https://www.khronos.org/registry/vulkan/specs/1.2-extensions/html/vkspec.html#renderpass-feedbackloop below>.
--
-- If a set of attachments alias each other, then all except the first to
-- be used in the render pass /must/ use an @initialLayout@ of
-- 'Vulkan.Core10.Enums.ImageLayout.IMAGE_LAYOUT_UNDEFINED', since the
-- earlier uses of the other aliases make their contents undefined. Once an
-- alias has been used and a different alias has been used after it, the
-- first alias /must/ not be used in any later subpasses. However, an
-- application /can/ assign the same image view to multiple aliasing
-- attachment indices, which allows that image view to be used multiple
-- times even if other aliases are used in between.
--
-- Note
--
-- Once an attachment needs the
-- 'Vulkan.Core10.Enums.AttachmentDescriptionFlagBits.ATTACHMENT_DESCRIPTION_MAY_ALIAS_BIT'
-- bit, there /should/ be no additional cost of introducing additional
-- aliases, and using these additional aliases /may/ allow more efficient
-- clearing of the attachments on multiple uses via
-- 'Vulkan.Core10.Enums.AttachmentLoadOp.ATTACHMENT_LOAD_OP_CLEAR'.

--
-- Each element of the @pColorAttachments@ array corresponds to an output
-- location in the shader, i.e. if the shader declares an output variable
-- decorated with a @Location@ value of __X__, then it uses the attachment
-- provided in @pColorAttachments@[__X__]. If the @attachment@ member of
-- any element of @pColorAttachments@ is
-- 'Vulkan.Core10.APIConstants.ATTACHMENT_UNUSED', writes to the
-- corresponding location by a fragment are discarded.
--
-- If @flags@ does not include
-- 'Vulkan.Core10.Enums.SubpassDescriptionFlagBits.SUBPASS_DESCRIPTION_SHADER_RESOLVE_BIT_QCOM',
-- and if @pResolveAttachments@ is not @NULL@, each of its elements
-- corresponds to a color attachment (the element in @pColorAttachments@ at
-- the same index), and a multisample resolve operation is defined for each
-- attachment. At the end of each subpass, multisample resolve operations
-- read the subpass’s color attachments, and resolve the samples for each
-- pixel within the render area to the same pixel location in the
-- corresponding resolve attachments, unless the resolve attachment index
-- is 'Vulkan.Core10.APIConstants.ATTACHMENT_UNUSED'.
--
-- Similarly, if @flags@ does not include
-- 'Vulkan.Core10.Enums.SubpassDescriptionFlagBits.SUBPASS_DESCRIPTION_SHADER_RESOLVE_BIT_QCOM',
-- and
-- 'Vulkan.Core12.Promoted_From_VK_KHR_depth_stencil_resolve.SubpassDescriptionDepthStencilResolve'::@pDepthStencilResolveAttachment@
-- is not @NULL@ and does not have the value
-- 'Vulkan.Core10.APIConstants.ATTACHMENT_UNUSED', it corresponds to the
-- depth\/stencil attachment in @pDepthStencilAttachment@, and multisample
-- resolve operations for depth and stencil are defined by
-- 'Vulkan.Core12.Promoted_From_VK_KHR_depth_stencil_resolve.SubpassDescriptionDepthStencilResolve'::@depthResolveMode@
-- and
-- 'Vulkan.Core12.Promoted_From_VK_KHR_depth_stencil_resolve.SubpassDescriptionDepthStencilResolve'::@stencilResolveMode@,
-- respectively. At the end of each subpass, multisample resolve operations
-- read the subpass’s depth\/stencil attachment, and resolve the samples
-- for each pixel to the same pixel location in the corresponding resolve
-- attachment. If
-- 'Vulkan.Core12.Promoted_From_VK_KHR_depth_stencil_resolve.SubpassDescriptionDepthStencilResolve'::@depthResolveMode@
-- is 'Vulkan.Core12.Enums.ResolveModeFlagBits.RESOLVE_MODE_NONE', then the
-- depth component of the resolve attachment is not written to and its
-- contents are preserved. Similarly, if
-- 'Vulkan.Core12.Promoted_From_VK_KHR_depth_stencil_resolve.SubpassDescriptionDepthStencilResolve'::@stencilResolveMode@
-- is 'Vulkan.Core12.Enums.ResolveModeFlagBits.RESOLVE_MODE_NONE', then the
-- stencil component of the resolve attachment is not written to and its
-- contents are preserved.
-- 'Vulkan.Core12.Promoted_From_VK_KHR_depth_stencil_resolve.SubpassDescriptionDepthStencilResolve'::@depthResolveMode@
-- is ignored if the 'Vulkan.Core10.Enums.Format.Format' of the
-- @pDepthStencilResolveAttachment@ does not have a depth component.
-- Similarly,
-- 'Vulkan.Core12.Promoted_From_VK_KHR_depth_stencil_resolve.SubpassDescriptionDepthStencilResolve'::@stencilResolveMode@
-- is ignored if the 'Vulkan.Core10.Enums.Format.Format' of the
-- @pDepthStencilResolveAttachment@ does not have a stencil component.
--
-- If the image subresource range referenced by the depth\/stencil
-- attachment is created with
-- 'Vulkan.Core10.Enums.ImageCreateFlagBits.IMAGE_CREATE_SAMPLE_LOCATIONS_COMPATIBLE_DEPTH_BIT_EXT',
-- then the multisample resolve operation uses the sample locations state
-- specified in the @sampleLocationsInfo@ member of the element of the
-- 'Vulkan.Extensions.VK_EXT_sample_locations.RenderPassSampleLocationsBeginInfoEXT'::@pPostSubpassSampleLocations@
-- for the subpass.
--
-- If @pDepthStencilAttachment@ is @NULL@, or if its attachment index is
-- 'Vulkan.Core10.APIConstants.ATTACHMENT_UNUSED', it indicates that no
-- depth\/stencil attachment will be used in the subpass.
--
-- The contents of an attachment within the render area become undefined at
-- the start of a subpass __S__ if all of the following conditions are
-- true:
--
-- -   The attachment is used as a color, depth\/stencil, or resolve
--     attachment in any subpass in the render pass.
--
-- -   There is a subpass __S1__ that uses or preserves the attachment, and
--     a subpass dependency from __S1__ to __S__.
--
-- -   The attachment is not used or preserved in subpass __S__.
--
-- In addition, the contents of an attachment within the render area become
-- undefined at the start of a subpass __S__ if all of the following
-- conditions are true:
--
-- -   'Vulkan.Core10.Enums.SubpassDescriptionFlagBits.SUBPASS_DESCRIPTION_SHADER_RESOLVE_BIT_QCOM'
--     is set.
--
-- -   The attachment is used as a color or depth\/stencil in the subpass.
--
-- Once the contents of an attachment become undefined in subpass __S__,
-- they remain undefined for subpasses in subpass dependency chains
-- starting with subpass __S__ until they are written again. However, they
-- remain valid for subpasses in other subpass dependency chains starting
-- with subpass __S1__ if those subpasses use or preserve the attachment.

-- specified by @dstStageMask@. It is also limited to access types in the

--
-- The
-- <https://www.khronos.org/registry/vulkan/specs/1.2-extensions/html/vkspec.html#synchronization-dependencies-available-and-visible availability and visibility operations>
-- defined by a subpass dependency affect the execution of

-- within the render pass.
--
-- Note
--
-- For non-attachment resources, the memory dependency expressed by subpass
-- dependency is nearly identical to that of a
-- 'Vulkan.Core10.OtherTypes.MemoryBarrier' (with matching @srcAccessMask@
-- and @dstAccessMask@ parameters) submitted as a part of a
-- 'Vulkan.Core10.CommandBufferBuilding.cmdPipelineBarrier' (with matching
-- @srcStageMask@ and @dstStageMask@ parameters). The only difference being
-- that its scopes are limited to the identified subpasses rather than
-- potentially affecting everything before and after.
--
-- For attachments however, subpass dependencies work more like a
-- 'Vulkan.Core10.OtherTypes.ImageMemoryBarrier' defined similarly to the
-- 'Vulkan.Core10.OtherTypes.MemoryBarrier' above, the queue family indices
-- set to 'Vulkan.Core10.APIConstants.QUEUE_FAMILY_IGNORED', and layouts as
-- follows:
--
-- -   The equivalent to @oldLayout@ is the attachment’s layout according
--     to the subpass description for @srcSubpass@.
--
-- -   The equivalent to @newLayout@ is the attachment’s layout according
--     to the subpass description for @dstSubpass@.

-- | VkFramebufferCreateInfo - Structure specifying parameters of a newly
-- created framebuffer
--
-- = Description
--
-- Applications /must/ ensure that all accesses to memory that backs image
-- subresources used as attachments in a given renderpass instance either
-- happen-before the
-- <https://www.khronos.org/registry/vulkan/specs/1.2-extensions/html/vkspec.html#renderpass-load-store-ops load operations>
-- for those attachments, or happen-after the
-- <https://www.khronos.org/registry/vulkan/specs/1.2-extensions/html/vkspec.html#renderpass-load-store-ops store operations>
-- for those attachments.
--
-- For depth\/stencil attachments, each aspect /can/ be used separately as
-- attachments and non-attachments as long as the non-attachment accesses
-- are also via an image subresource in either the
-- 'Vulkan.Core10.Enums.ImageLayout.IMAGE_LAYOUT_DEPTH_READ_ONLY_STENCIL_ATTACHMENT_OPTIMAL'
-- layout or the
-- 'Vulkan.Core10.Enums.ImageLayout.IMAGE_LAYOUT_DEPTH_ATTACHMENT_STENCIL_READ_ONLY_OPTIMAL'
-- layout, and the attachment resource uses whichever of those two layouts
-- the image accesses do not. Use of non-attachment aspects in this case is
-- only well defined if the attachment is used in the subpass where the
-- non-attachment access is being made, or the layout of the image
-- subresource is constant throughout the entire render pass instance,
-- including the @initialLayout@ and @finalLayout@.
--
-- Note
--
-- These restrictions mean that the render pass has full knowledge of all
-- uses of all of the attachments, so that the implementation is able to
-- make correct decisions about when and how to perform layout transitions,
-- when to overlap execution of subpasses, etc.
--
-- It is legal for a subpass to use no color or depth\/stencil attachments,
-- either because it has no attachment references or because all of them
-- are 'Vulkan.Core10.APIConstants.ATTACHMENT_UNUSED'. This kind of subpass
-- /can/ use shader side effects such as image stores and atomics to
-- produce an output. In this case, the subpass continues to use the
-- @width@, @height@, and @layers@ of the framebuffer to define the
-- dimensions of the rendering area, and the @rasterizationSamples@ from
-- each pipeline’s
-- 'Vulkan.Core10.Pipeline.PipelineMultisampleStateCreateInfo' to define
-- the number of samples used in rasterization; however, if
-- 'Vulkan.Core10.DeviceInitialization.PhysicalDeviceFeatures'::@variableMultisampleRate@
-- is 'Vulkan.Core10.FundamentalTypes.FALSE', then all pipelines to be
-- bound with the subpass /must/ have the same value for
-- 'Vulkan.Core10.Pipeline.PipelineMultisampleStateCreateInfo'::@rasterizationSamples@.
