  -- == Description
  --
  -- The @VK_KHR_wayland_surface@ extension is an instance extension. It
  -- provides a mechanism to create a 'Vulkan.Extensions.Handles.SurfaceKHR'
  -- object (defined by the @VK_KHR_surface@ extension) that refers to a
  -- Wayland @wl_surface@, as well as a query to determine support for
  -- rendering to a Wayland compositor.
  --
  -- == New Commands
  --
  -- -   'createWaylandSurfaceKHR'
  --
  -- -   'getPhysicalDeviceWaylandPresentationSupportKHR'
  --
  -- == New Structures
  --
  -- -   'WaylandSurfaceCreateInfoKHR'
  --
  -- == New Bitmasks
  --
  -- -   'WaylandSurfaceCreateFlagsKHR'
  --
  -- == New Enum Constants
  --
  -- -   'KHR_WAYLAND_SURFACE_EXTENSION_NAME'
  --
  -- -   'KHR_WAYLAND_SURFACE_SPEC_VERSION'
  --
  -- -   Extending 'Vulkan.Core10.Enums.StructureType.StructureType':
  --
  --     -   'Vulkan.Core10.Enums.StructureType.STRUCTURE_TYPE_WAYLAND_SURFACE_CREATE_INFO_KHR'
  --
  -- == Issues
  --
  -- 1) Does Wayland need a way to query for compatibility between a
  -- particular physical device and a specific Wayland display? This would be
  -- a more general query than
  -- 'Vulkan.Extensions.VK_KHR_surface.getPhysicalDeviceSurfaceSupportKHR':
  -- if the Wayland-specific query returned
  -- 'Vulkan.Core10.FundamentalTypes.TRUE' for a
  -- ('Vulkan.Core10.Handles.PhysicalDevice', @struct wl_display*@) pair,
  -- then the physical device could be assumed to support presentation to any
  -- 'Vulkan.Extensions.Handles.SurfaceKHR' for surfaces on the display.
  --
  -- __RESOLVED__: Yes. 'getPhysicalDeviceWaylandPresentationSupportKHR' was
  -- added to address this issue.
  --
  -- 2) Should we require surfaces created with 'createWaylandSurfaceKHR' to
  -- support the 'Vulkan.Extensions.VK_KHR_surface.PRESENT_MODE_MAILBOX_KHR'
  -- present mode?
  --
  -- __RESOLVED__: Yes. Wayland is an inherently mailbox window system and
  -- mailbox support is required for some Wayland compositor interactions to
  -- work as expected. While handling these interactions may be possible with
  -- 'Vulkan.Extensions.VK_KHR_surface.PRESENT_MODE_FIFO_KHR', it is much
  -- more difficult to do without deadlock and requiring all Wayland
  -- applications to be able to support implementations which only support
  -- 'Vulkan.Extensions.VK_KHR_surface.PRESENT_MODE_FIFO_KHR' would be an
  -- onerous restriction on application developers.
  --
  -- == Version History
  --
  -- -   Revision 1, 2015-09-23 (Jesse Hall)
  --
  --     -   Initial draft, based on the previous contents of
  --         VK_EXT_KHR_swapchain (later renamed VK_EXT_KHR_surface).
  --
  -- -   Revision 2, 2015-10-02 (James Jones)
  --
  --     -   Added vkGetPhysicalDeviceWaylandPresentationSupportKHR() to
  --         resolve issue #1.
  --
  --     -   Adjusted wording of issue #1 to match the agreed-upon solution.
  --
  --     -   Renamed “window” parameters to “surface” to match Wayland
  --         conventions.
  --
  -- -   Revision 3, 2015-10-26 (Ian Elliott)
  --
  --     -   Renamed from VK_EXT_KHR_wayland_surface to
  --         VK_KHR_wayland_surface.
  --
  -- -   Revision 4, 2015-11-03 (Daniel Rakos)
  --
  --     -   Added allocation callbacks to vkCreateWaylandSurfaceKHR.
  --
  -- -   Revision 5, 2015-11-28 (Daniel Rakos)
  --
  --     -   Updated the surface create function to take a pCreateInfo
  --         structure.
  --
  -- -   Revision 6, 2017-02-08 (Faith Ekstrand)
  --
  --     -   Added the requirement that implementations support
  --         'Vulkan.Extensions.VK_KHR_surface.PRESENT_MODE_MAILBOX_KHR'.
  --
  --     -   Added wording about interactions between
  --         'Vulkan.Extensions.VK_KHR_swapchain.queuePresentKHR' and the
  --         Wayland requests sent to the compositor.
