-- == Description
--
-- The @VK_FUCHSIA_imagepipe_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 Fuchsia @imagePipeHandle@.
--
-- == New Commands
--
-- -   'createImagePipeSurfaceFUCHSIA'
--
-- == New Structures
--
-- -   'ImagePipeSurfaceCreateInfoFUCHSIA'
--
-- == New Bitmasks
--
-- -   'ImagePipeSurfaceCreateFlagsFUCHSIA'
--
-- == New Enum Constants
