  -- == Description
  --
  -- The @VK_KHR_android_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 an
  -- 'ANativeWindow', Android’s native surface type. The 'ANativeWindow'
  -- represents the producer endpoint of any buffer queue, regardless of
  -- consumer endpoint. Common consumer endpoints for @ANativeWindows@ are
  -- the system window compositor, video encoders, and application-specific
  -- compositors importing the images through a @SurfaceTexture@.
  --
  -- == New Base Types
  --
  -- -   'ANativeWindow'
  --
  -- == New Commands
  --
  -- -   'createAndroidSurfaceKHR'
  --
  -- == New Structures
  --
  -- -   'AndroidSurfaceCreateInfoKHR'
  --
  -- == New Bitmasks
  --
  -- -   'AndroidSurfaceCreateFlagsKHR'
  --
  -- == New Enum Constants
  --
  -- -   'KHR_ANDROID_SURFACE_EXTENSION_NAME'
  --
  -- -   'KHR_ANDROID_SURFACE_SPEC_VERSION'
  --
  -- -   Extending 'Vulkan.Core10.Enums.StructureType.StructureType':
  --
  --     -   'Vulkan.Core10.Enums.StructureType.STRUCTURE_TYPE_ANDROID_SURFACE_CREATE_INFO_KHR'
  --
  -- == Issues
  --
  -- 1) Does Android need a way to query for compatibility between a
  -- particular physical device (and queue family?) and a specific Android
  -- display?
  --
  -- __RESOLVED__: No. Currently on Android, any physical device is expected
  -- to be able to present to the system compositor, and all queue families
  -- must support the necessary image layout transitions and synchronization
  -- operations.

  --
  --     -   Updated the surface create function to take a pCreateInfo
  --         structure.
  --
  -- -   Revision 6, 2016-01-14 (James Jones)

  -- | vkCreateAndroidSurfaceKHR - Create a
  -- 'Vulkan.Extensions.Handles.SurfaceKHR' object for an Android native
  -- window
  --
  -- = Description
  --
  -- During the lifetime of a surface created using a particular
  -- 'ANativeWindow' handle any attempts to create another surface for the
  -- same 'ANativeWindow' and any attempts to connect to the same
  -- 'ANativeWindow' through other platform mechanisms will fail.
  --
  -- Note
  --
  -- In particular, only one 'Vulkan.Extensions.Handles.SurfaceKHR' /can/
  -- exist at a time for a given window. Similarly, a native window /cannot/
  -- be used by both a 'Vulkan.Extensions.Handles.SurfaceKHR' and
  -- @EGLSurface@ simultaneously.
  --
  -- If successful, 'createAndroidSurfaceKHR' increments the
  -- 'ANativeWindow'’s reference count, and
  -- 'Vulkan.Extensions.VK_KHR_surface.destroySurfaceKHR' will decrement it.
  --
  -- On Android, when a swapchain’s @imageExtent@ does not match the
  -- surface’s @currentExtent@, the presentable images will be scaled to the
  -- surface’s dimensions during presentation. @minImageExtent@ is (1,1), and
  -- @maxImageExtent@ is the maximum image size supported by the consumer.
  -- For the system compositor, @currentExtent@ is the window size (i.e. the
  -- consumer’s preferred size).
