  -- == Description
  --
  -- This extension provides the ability to use /DRM format modifiers/ with
  -- images, enabling Vulkan to better integrate with the Linux ecosystem of
  -- graphics, video, and display APIs.
  --
  -- Its functionality closely overlaps with
  -- @EGL_EXT_image_dma_buf_import_modifiers@<https://registry.khronos.org/vulkan/specs/1.3-extensions/html/vkspec.html#VK_EXT_image_drm_format_modifier-fn2 2>^
  -- and
  -- @EGL_MESA_image_dma_buf_export@<https://registry.khronos.org/vulkan/specs/1.3-extensions/html/vkspec.html#VK_EXT_image_drm_format_modifier-fn3 3>^.
  -- Unlike the EGL extensions, this extension does not require the use of a
  -- specific handle type (such as a dma_buf) for external memory and
  -- provides more explicit control of image creation.
  --
  -- == Introduction to DRM Format Modifiers
  --
  -- A /DRM format modifier/ is a 64-bit, vendor-prefixed, semi-opaque
  -- unsigned integer. Most /modifiers/ represent a concrete, vendor-specific
  -- tiling format for images. Some exceptions are @DRM_FORMAT_MOD_LINEAR@
  -- (which is not vendor-specific); @DRM_FORMAT_MOD_NONE@ (which is an alias
  -- of @DRM_FORMAT_MOD_LINEAR@ due to historical accident); and
  -- @DRM_FORMAT_MOD_INVALID@ (which does not represent a tiling format). The
  -- /modifier’s/ vendor prefix consists of the 8 most significant bits. The
  -- canonical list of /modifiers/ and vendor prefixes is found in
  -- <https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/include/uapi/drm/drm_fourcc.h drm_fourcc.h>
  -- in the Linux kernel source. The other dominant source of /modifiers/ are
  -- vendor kernel trees.
  --
  -- One goal of /modifiers/ in the Linux ecosystem is to enumerate for each
  -- vendor a reasonably sized set of tiling formats that are appropriate for
  -- images shared across processes, APIs, and\/or devices, where each
  -- participating component may possibly be from different vendors. A
  -- non-goal is to enumerate all tiling formats supported by all vendors.
  -- Some tiling formats used internally by vendors are inappropriate for
  -- sharing; no /modifiers/ should be assigned to such tiling formats.
  --
  -- Modifier values typically do not /describe/ memory layouts. More
  -- precisely, a /modifier/\'s lower 56 bits usually have no structure.
  -- Instead, modifiers /name/ memory layouts; they name a small set of
  -- vendor-preferred layouts for image sharing. As a consequence, in each
  -- vendor namespace the modifier values are often sequentially allocated
  -- starting at 1.
  --
  -- Each /modifier/ is usually supported by a single vendor and its name
  -- matches the pattern @{VENDOR}_FORMAT_MOD_*@ or
  -- @DRM_FORMAT_MOD_{VENDOR}_*@. Examples are @I915_FORMAT_MOD_X_TILED@ and
  -- @DRM_FORMAT_MOD_BROADCOM_VC4_T_TILED@. An exception is
  -- @DRM_FORMAT_MOD_LINEAR@, which is supported by most vendors.
  --
  -- Many APIs in Linux use /modifiers/ to negotiate and specify the memory
  -- layout of shared images. For example, a Wayland compositor and Wayland
  -- client may, by relaying /modifiers/ over the Wayland protocol
  -- @zwp_linux_dmabuf_v1@, negotiate a vendor-specific tiling format for a
  -- shared @wl_buffer@. The client may allocate the underlying memory for
  -- the @wl_buffer@ with GBM, providing the chosen /modifier/ to
  -- @gbm_bo_create_with_modifiers@. The client may then import the
  -- @wl_buffer@ into Vulkan for producing image content, providing the
  -- resource’s dma_buf to
  -- 'Vulkan.Extensions.VK_KHR_external_memory_fd.ImportMemoryFdInfoKHR' and
  -- its /modifier/ to 'ImageDrmFormatModifierExplicitCreateInfoEXT'. The
  -- compositor may then import the @wl_buffer@ into OpenGL for sampling,
  -- providing the resource’s dma_buf and /modifier/ to @eglCreateImage@. The
  -- compositor may also bypass OpenGL and submit the @wl_buffer@ directly to
  -- the kernel’s display API, providing the dma_buf and /modifier/ through
  -- @drm_mode_fb_cmd2@.
  --
  -- == Format Translation
  --
  -- /Modifier/-capable APIs often pair /modifiers/ with DRM formats, which
  -- are defined in
  -- <https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/include/uapi/drm/drm_fourcc.h drm_fourcc.h>.
  -- However, @VK_EXT_image_drm_format_modifier@ uses
  -- 'Vulkan.Core10.Enums.Format.Format' instead of DRM formats. The
  -- application must convert between 'Vulkan.Core10.Enums.Format.Format' and
  -- DRM format when it sends or receives a DRM format to or from an external
  -- API.
  --
  -- The mapping from 'Vulkan.Core10.Enums.Format.Format' to DRM format is
  -- lossy. Therefore, when receiving a DRM format from an external API,
  -- often the application must use information from the external API to
  -- accurately map the DRM format to a 'Vulkan.Core10.Enums.Format.Format'.
  -- For example, DRM formats do not distinguish between RGB and sRGB (as of
  -- 2018-03-28); external information is required to identify the image’s
  -- color space.
  --
  -- The mapping between 'Vulkan.Core10.Enums.Format.Format' and DRM format
  -- is also incomplete. For some DRM formats there exist no corresponding
  -- Vulkan format, and for some Vulkan formats there exist no corresponding
  -- DRM format.
  --
  -- == Usage Patterns
  --
  -- Three primary usage patterns are intended for this extension:
  --
  -- -   __Negotiation.__ The application negotiates with /modifier/-aware,
  --     external components to determine sets of image creation parameters
  --     supported among all components.
  --
  --     In the Linux ecosystem, the negotiation usually assumes the image is
  --     a 2D, single-sampled, non-mipmapped, non-array image; this extension
  --     permits that assumption but does not require it. The result of the
  --     negotiation usually resembles a set of tuples such as /(drmFormat,
  --     drmFormatModifier)/, where each participating component supports all
  --     tuples in the set.
  --
  --     Many details of this negotiation - such as the protocol used during
  --     negotiation, the set of image creation parameters expressible in the
  --     protocol, and how the protocol chooses which process and which API
  --     will create the image - are outside the scope of this specification.
  --
  --     In this extension,
  --     'Vulkan.Core11.Promoted_From_VK_KHR_get_physical_device_properties2.getPhysicalDeviceFormatProperties2'
  --     with 'DrmFormatModifierPropertiesListEXT' serves a primary role
  --     during the negotiation, and
  --     'Vulkan.Core11.Promoted_From_VK_KHR_get_physical_device_properties2.getPhysicalDeviceImageFormatProperties2'
  --     with 'PhysicalDeviceImageDrmFormatModifierInfoEXT' serves a
  --     secondary role.
  --
  -- -   __Import.__ The application imports an image with a /modifier/.
  --
  --     In this pattern, the application receives from an external source
  --     the image’s memory and its creation parameters, which are often the
  --     result of the negotiation described above. Some image creation
  --     parameters are implicitly defined by the external source; for
  --     example, 'Vulkan.Core10.Enums.ImageType.IMAGE_TYPE_2D' is often
  --     assumed. Some image creation parameters are usually explicit, such
  --     as the image’s @format@, @drmFormatModifier@, and @extent@; and each
  --     plane’s @offset@ and @rowPitch@.
  --
  --     Before creating the image, the application first verifies that the
  --     physical device supports the received creation parameters by
  --     querying
  --     'Vulkan.Core11.Promoted_From_VK_KHR_get_physical_device_properties2.getPhysicalDeviceFormatProperties2'
  --     with 'DrmFormatModifierPropertiesListEXT' and
  --     'Vulkan.Core11.Promoted_From_VK_KHR_get_physical_device_properties2.getPhysicalDeviceImageFormatProperties2'
  --     with 'PhysicalDeviceImageDrmFormatModifierInfoEXT'. Then the
  --     application creates the image by chaining
  --     'ImageDrmFormatModifierExplicitCreateInfoEXT' and
  --     'Vulkan.Core11.Promoted_From_VK_KHR_external_memory.ExternalMemoryImageCreateInfo'
  --     onto 'Vulkan.Core10.Image.ImageCreateInfo'.
  --
  -- -   __Export.__ The application creates an image and allocates its
  --     memory. Then the application exports to /modifier/-aware consumers
  --     the image’s memory handles; its creation parameters; its /modifier/;
  --     and the <VkSubresourceLayout.html offset>,
  --     <VkSubresourceLayout.html size>, and
  --     <VkSubresourceLayout.html rowPitch> of each /memory plane/.
  --
  --     In this pattern, the Vulkan device is the authority for the image;
  --     it is the allocator of the image’s memory and the decider of the
  --     image’s creation parameters. When choosing the image’s creation
  --     parameters, the application usually chooses a tuple /(format,
  --     drmFormatModifier)/ from the result of the negotiation described
  --     above. The negotiation’s result often contains multiple tuples that
  --     share the same format but differ in their /modifier/. In this case,
  --     the application should defer the choice of the image’s /modifier/ to
  --     the Vulkan implementation by providing all such /modifiers/ to
  --     'ImageDrmFormatModifierListCreateInfoEXT'::@pDrmFormatModifiers@;
  --     and the implementation should choose from @pDrmFormatModifiers@ the
  --     optimal /modifier/ in consideration with the other image parameters.
  --
  --     The application creates the image by chaining
  --     'ImageDrmFormatModifierListCreateInfoEXT' and
  --     'Vulkan.Core11.Promoted_From_VK_KHR_external_memory.ExternalMemoryImageCreateInfo'
  --     onto 'Vulkan.Core10.Image.ImageCreateInfo'. The protocol and APIs by
  --     which the application will share the image with external consumers
  --     will likely determine the value of
  --     'Vulkan.Core11.Promoted_From_VK_KHR_external_memory.ExternalMemoryImageCreateInfo'::@handleTypes@.
  --     The implementation chooses for the image an optimal /modifier/ from
  --     'ImageDrmFormatModifierListCreateInfoEXT'::@pDrmFormatModifiers@.
  --     The application then queries the implementation-chosen /modifier/
  --     with 'getImageDrmFormatModifierPropertiesEXT', and queries the
  --     memory layout of each plane with
  --     'Vulkan.Core10.Image.getImageSubresourceLayout'.
  --
  --     The application then allocates the image’s memory with
  --     'Vulkan.Core10.Memory.MemoryAllocateInfo', adding chained extending
  --     structures for external memory; binds it to the image; and exports
  --     the memory, for example, with
  --     'Vulkan.Extensions.VK_KHR_external_memory_fd.getMemoryFdKHR'.
  --
  --     Finally, the application sends the image’s creation parameters, its
  --     /modifier/, its per-plane memory layout, and the exported memory
  --     handle to the external consumers. The details of how the application
  --     transmits this information to external consumers is outside the
  --     scope of this specification.

  --
  -- == Issues
  --
  -- 1) Should this extension define a single DRM format modifier per
  -- 'Vulkan.Core10.Handles.Image'? Or define one per plane?
  --
  -- +
  --
  -- __RESOLVED__: There exists a single DRM format modifier per
  -- 'Vulkan.Core10.Handles.Image'.
  --
  -- __DISCUSSION__: Prior art, such as
  -- @EGL_EXT_image_dma_buf_import_modifiers@<https://registry.khronos.org/vulkan/specs/1.3-extensions/html/vkspec.html#VK_EXT_image_drm_format_modifier-fn2 2>^,
  -- @struct drm_mode_fb_cmd2@<https://registry.khronos.org/vulkan/specs/1.3-extensions/html/vkspec.html#VK_EXT_image_drm_format_modifier-fn4 4>^,
  -- and
  -- @struct gbm_import_fd_modifier_data@<https://registry.khronos.org/vulkan/specs/1.3-extensions/html/vkspec.html#VK_EXT_image_drm_format_modifier-fn5 5>^,
  -- allows defining one /modifier/ per plane. However, developers of the GBM
  -- and kernel APIs concede it was a mistake. Beginning in Linux 4.10, the
  -- kernel requires that the application provide the same DRM format
  -- /modifier/ for each plane. (See Linux commit
  -- <https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=bae781b259269590109e8a4a8227331362b88212 bae781b259269590109e8a4a8227331362b88212>).
  -- And GBM provides an entry point, @gbm_bo_get_modifier@, for querying the
  -- /modifier/ of the image but does not provide one to query the modifier
  -- of individual planes.
  --
  -- 2) When creating an image with
  -- 'ImageDrmFormatModifierExplicitCreateInfoEXT', which is typically used
  -- when /importing/ an image, should the application explicitly provide the
  -- size of each plane?
  --
  -- +
  --
  -- __RESOLVED__: No. The application /must/ not provide the size. To
  -- enforce this, the API requires that
  -- 'ImageDrmFormatModifierExplicitCreateInfoEXT'::@pPlaneLayouts->size@
  -- /must/ be 0.
  --
  -- __DISCUSSION__: Prior art, such as
  -- @EGL_EXT_image_dma_buf_import_modifiers@<https://registry.khronos.org/vulkan/specs/1.3-extensions/html/vkspec.html#VK_EXT_image_drm_format_modifier-fn2 2>^,
  -- @struct drm_mode_fb_cmd2@<https://registry.khronos.org/vulkan/specs/1.3-extensions/html/vkspec.html#VK_EXT_image_drm_format_modifier-fn4 4>^,
  -- and
  -- @struct gbm_import_fd_modifier_data@<https://registry.khronos.org/vulkan/specs/1.3-extensions/html/vkspec.html#VK_EXT_image_drm_format_modifier-fn5 5>^,
  -- omits from the API the size of each plane. Instead, the APIs infer each
  -- plane’s size from the import parameters, which include the image’s pixel
  -- format and a dma_buf, offset, and row pitch for each plane.
  --
  -- However, Vulkan differs from EGL and GBM with regards to image creation
  -- in the following ways:
  --
  -- -   __Undedicated allocation by default.__ When importing or exporting a
  --     set of dma_bufs as an @EGLImage@ or @gbm_bo@, common practice
  --     mandates that each dma_buf’s memory be dedicated (in the sense of
  --     @VK_KHR_dedicated_allocation@) to the image (though not necessarily
  --     dedicated to a single plane). In particular, neither the GBM
  --     documentation nor the EGL extension specifications explicitly state
  --     this requirement, but in light of common practice this is likely due
  --     to under-specification rather than intentional omission. In
  --     contrast, @VK_EXT_image_drm_format_modifier@ permits, but does not
  --     require, the implementation to require dedicated allocations for
  --     images created with
  --     'Vulkan.Core10.Enums.ImageTiling.IMAGE_TILING_DRM_FORMAT_MODIFIER_EXT'.
  --
  -- -   __Separation of image creation and memory allocation.__ When
  --     importing a set of dma_bufs as an @EGLImage@ or @gbm_bo@, EGL and
  --     GBM create the image resource and bind it to memory (the dma_bufs)
  --     simultaneously. This allows EGL and GBM to query each dma_buf’s size
  --     during image creation. In Vulkan, image creation and memory
  --     allocation are independent unless a dedicated allocation is used (as
  --     in @VK_KHR_dedicated_allocation@). Therefore, without requiring
  --     dedicated allocation, Vulkan cannot query the size of each dma_buf
  --     (or other external handle) when calculating the image’s memory
  --     layout. Even if dedication allocation were required, Vulkan cannot
  --     calculate the image’s memory layout until after the image is bound
  --     to its dma_ufs.
  --
  -- The above differences complicate the potential inference of plane size
  -- in Vulkan. Consider the following problematic cases:
  --
  -- -   __Padding.__ Some plane of the image may require
  --     implementation-dependent padding.
  --
  -- -   __Metadata.__ For some /modifiers/, the image may have a metadata
  --     plane which requires a non-trivial calculation to determine its
  --     size.
  --
  -- -   __Mipmapped, array, and 3D images.__ The implementation may support
  --     'Vulkan.Core10.Enums.ImageTiling.IMAGE_TILING_DRM_FORMAT_MODIFIER_EXT'
  --     for images whose @mipLevels@, @arrayLayers@, or @depth@ is greater
  --     than 1. For such images with certain /modifiers/, the calculation of
  --     each plane’s size may be non-trivial.
  --
  -- However, an application-provided plane size solves none of the above
  -- problems.
  --
  -- For simplicity, consider an external image with a single memory plane.
  -- The implementation is obviously capable calculating the image’s size
  -- when its tiling is
  -- 'Vulkan.Core10.Enums.ImageTiling.IMAGE_TILING_OPTIMAL'. Likewise, any
  -- reasonable implementation is capable of calculating the image’s size
  -- when its tiling uses a supported /modifier/.
  --
  -- Suppose that the external image’s size is smaller than the
  -- implementation-calculated size. If the application provided the external
  -- image’s size to 'Vulkan.Core10.Image.createImage', the implementation
  -- would observe the mismatched size and recognize its inability to
  -- comprehend the external image’s layout (unless the implementation used
  -- the application-provided size to select a refinement of the tiling
  -- layout indicated by the /modifier/, which is strongly discouraged). The
  -- implementation would observe the conflict, and reject image creation
  -- with
  -- 'Vulkan.Core10.Enums.Result.ERROR_INVALID_DRM_FORMAT_MODIFIER_PLANE_LAYOUT_EXT'.
  -- On the other hand, if the application did not provide the external
  -- image’s size to 'Vulkan.Core10.Image.createImage', then the application
  -- would observe after calling
  -- 'Vulkan.Core10.MemoryManagement.getImageMemoryRequirements' that the
  -- external image’s size is less than the size required by the
  -- implementation. The application would observe the conflict and refuse to
  -- bind the 'Vulkan.Core10.Handles.Image' to the external memory. In both
  -- cases, the result is explicit failure.
  --
  -- Suppose that the external image’s size is larger than the
  -- implementation-calculated size. If the application provided the external
  -- image’s size to 'Vulkan.Core10.Image.createImage', for reasons similar
  -- to above the implementation would observe the mismatched size and
  -- recognize its inability to comprehend the image data residing in the
  -- extra size. The implementation, however, must assume that image data
  -- resides in the entire size provided by the application. The
  -- implementation would observe the conflict and reject image creation with
  -- 'Vulkan.Core10.Enums.Result.ERROR_INVALID_DRM_FORMAT_MODIFIER_PLANE_LAYOUT_EXT'.
  -- On the other hand, if the application did not provide the external
  -- image’s size to 'Vulkan.Core10.Image.createImage', then the application
  -- would observe after calling
  -- 'Vulkan.Core10.MemoryManagement.getImageMemoryRequirements' that the
  -- external image’s size is larger than the implementation-usable size. The
  -- application would observe the conflict and refuse to bind the
  -- 'Vulkan.Core10.Handles.Image' to the external memory. In both cases, the
  -- result is explicit failure.
  --
  -- Therefore, an application-provided size provides no benefit, and this
  -- extension should not require it. This decision renders
  -- 'Vulkan.Core10.Image.SubresourceLayout'::@size@ an unused field during
  -- image creation, and thus introduces a risk that implementations may
  -- require applications to submit sideband creation parameters in the
  -- unused field. To prevent implementations from relying on sideband data,
  -- this extension /requires/ the application to set @size@ to 0.

  -- | VkDrmFormatModifierPropertiesEXT - Structure specifying properties of a
  -- format when combined with a DRM format modifier
  --
  -- = Description
  --
  -- The returned @drmFormatModifierTilingFeatures@ /must/ contain at least
  -- one bit.
  --
  -- The implementation /must/ not return @DRM_FORMAT_MOD_INVALID@ in
  -- @drmFormatModifier@.
  --
  -- An image’s /memory planecount/ (as returned by
  -- @drmFormatModifierPlaneCount@) is distinct from its /format planecount/
  -- (in the sense of
  -- <https://registry.khronos.org/vulkan/specs/1.3-extensions/html/vkspec.html#formats-requiring-sampler-ycbcr-conversion multi-planar>
  -- Y′CBCR formats). In
  -- 'Vulkan.Core10.Enums.ImageAspectFlagBits.ImageAspectFlags', each
  -- @VK_IMAGE_ASPECT_MEMORY_PLANE_i_BIT_EXT@ represents a /memory plane/ and
  -- each @VK_IMAGE_ASPECT_PLANE_i_BIT@ a /format plane/.
  --
  -- An image’s set of /format planes/ is an ordered partition of the image’s
  -- __content__ into separable groups of format components. The ordered
  -- partition is encoded in the name of each
  -- 'Vulkan.Core10.Enums.Format.Format'. For example,
  -- 'Vulkan.Core10.Enums.Format.FORMAT_G8_B8R8_2PLANE_420_UNORM' contains
  -- two /format planes/; the first plane contains the green component and
  -- the second plane contains the blue component and red component. If the
  -- format name does not contain @PLANE@, then the format contains a single
  -- plane; for example, 'Vulkan.Core10.Enums.Format.FORMAT_R8G8B8A8_UNORM'.
  -- Some commands, such as
  -- 'Vulkan.Core10.CommandBufferBuilding.cmdCopyBufferToImage', do not
  -- operate on all format components in the image, but instead operate only
  -- on the /format planes/ explicitly chosen by the application and operate
  -- on each /format plane/ independently.
  --
  -- An image’s set of /memory planes/ is an ordered partition of the image’s
  -- __memory__ rather than the image’s __content__. Each /memory plane/ is a
  -- contiguous range of memory. The union of an image’s /memory planes/ is
  -- not necessarily contiguous.
  --
  -- If an image is
  -- <https://registry.khronos.org/vulkan/specs/1.3-extensions/html/vkspec.html#glossary-linear-resource linear>,
  -- then the partition is the same for /memory planes/ and for /format
  -- planes/. Therefore, if the returned @drmFormatModifier@ is
  -- @DRM_FORMAT_MOD_LINEAR@, then @drmFormatModifierPlaneCount@ /must/ equal
  -- the /format planecount/, and @drmFormatModifierTilingFeatures@ /must/ be
  -- identical to the
  -- 'Vulkan.Core11.Promoted_From_VK_KHR_get_physical_device_properties2.FormatProperties2'::@linearTilingFeatures@
  -- returned in the same @pNext@ chain.
  --
  -- If an image is
  -- <https://registry.khronos.org/vulkan/specs/1.3-extensions/html/vkspec.html#glossary-linear-resource non-linear>,
  -- then the partition of the image’s __memory__ into /memory planes/ is
  -- implementation-specific and /may/ be unrelated to the partition of the
  -- image’s __content__ into /format planes/. For example, consider an image
  -- whose @format@ is
  -- 'Vulkan.Core10.Enums.Format.FORMAT_G8_B8_R8_3PLANE_420_UNORM', @tiling@
  -- is
  -- 'Vulkan.Core10.Enums.ImageTiling.IMAGE_TILING_DRM_FORMAT_MODIFIER_EXT',
  -- whose @drmFormatModifier@ is not @DRM_FORMAT_MOD_LINEAR@, and @flags@
  -- lacks
  -- 'Vulkan.Core10.Enums.ImageCreateFlagBits.IMAGE_CREATE_DISJOINT_BIT'. The
  -- image has 3 /format planes/, and commands such
  -- 'Vulkan.Core10.CommandBufferBuilding.cmdCopyBufferToImage' act on each
  -- /format plane/ independently as if the data of each /format plane/ were
  -- separable from the data of the other planes. In a straightforward
  -- implementation, the implementation /may/ store the image’s content in 3
  -- adjacent /memory planes/ where each /memory plane/ corresponds exactly
  -- to a /format plane/. However, the implementation /may/ also store the
  -- image’s content in a single /memory plane/ where all format components
  -- are combined using an implementation-private block-compressed format; or
  -- the implementation /may/ store the image’s content in a collection of 7
  -- adjacent /memory planes/ using an implementation-private sharding
  -- technique. Because the image is non-linear and non-disjoint, the
  -- implementation has much freedom when choosing the image’s placement in
  -- memory.
