  -- == Description
  --
  -- A @dma_buf@ is a type of file descriptor, defined by the Linux kernel,
  -- that allows sharing memory across kernel device drivers and across
  -- processes. This extension enables applications to import a @dma_buf@ as
  -- 'Vulkan.Core10.Handles.DeviceMemory', to export
  -- 'Vulkan.Core10.Handles.DeviceMemory' as a @dma_buf@, and to create
  -- 'Vulkan.Core10.Handles.Buffer' objects that /can/ be bound to that
  -- memory.
  --
  -- == New Enum Constants
  --
  -- -   'EXT_EXTERNAL_MEMORY_DMA_BUF_EXTENSION_NAME'
  --
  -- -   'EXT_EXTERNAL_MEMORY_DMA_BUF_SPEC_VERSION'
  --
  -- -   Extending
  --     'Vulkan.Core11.Enums.ExternalMemoryHandleTypeFlagBits.ExternalMemoryHandleTypeFlagBits':
  --
  --     -   'Vulkan.Core11.Enums.ExternalMemoryHandleTypeFlagBits.EXTERNAL_MEMORY_HANDLE_TYPE_DMA_BUF_BIT_EXT'
  --
  -- == Issues
  --
  -- 1) How does the application, when creating a
  -- 'Vulkan.Core10.Handles.Image' that it intends to bind to @dma_buf@
  -- 'Vulkan.Core10.Handles.DeviceMemory' containing an externally produced
  -- image, specify the memory layout (such as row pitch and DRM format
  -- modifier) of the 'Vulkan.Core10.Handles.Image'? In other words, how does
  -- the application achieve behavior comparable to that provided by
  -- <https://registry.khronos.org/EGL/extensions/EXT/EGL_EXT_image_dma_buf_import.txt EGL_EXT_image_dma_buf_import>
  -- and
  -- <https://registry.khronos.org/EGL/extensions/EXT/EGL_EXT_image_dma_buf_import_modifiers.txt EGL_EXT_image_dma_buf_import_modifiers>
  -- ?
  --
  -- __RESOLVED__: Features comparable to those in
  -- <https://registry.khronos.org/EGL/extensions/EXT/EGL_EXT_image_dma_buf_import.txt EGL_EXT_image_dma_buf_import>
  -- and
  -- <https://registry.khronos.org/EGL/extensions/EXT/EGL_EXT_image_dma_buf_import_modifiers.txt EGL_EXT_image_dma_buf_import_modifiers>
  -- will be provided by an extension layered atop this one.
  --
  -- 2) Without the ability to specify the memory layout of external
  -- @dma_buf@ images, how is this extension useful?
  --
  -- __RESOLVED__: This extension provides exactly one new feature: the
  -- ability to import\/export between @dma_buf@ and
  -- 'Vulkan.Core10.Handles.DeviceMemory'. This feature, together with
  -- features provided by @VK_KHR_external_memory_fd@, is sufficient to bind
  -- a 'Vulkan.Core10.Handles.Buffer' to @dma_buf@.
