-- == Description
--
-- The @VK_EXT_headless_surface@ extension is an instance extension. It
-- provides a mechanism to create 'Vulkan.Extensions.Handles.SurfaceKHR'
-- objects independently of any window system or display device. The
-- presentation operation for a swapchain created from a headless surface
-- is by default a no-op, resulting in no externally-visible result.
--
-- Because there is no real presentation target, future extensions can
-- layer on top of the headless surface to introduce arbitrary or
-- customisable sets of restrictions or features. These could include
-- features like saving to a file or restrictions to emulate a particular
-- presentation target.
--
-- This functionality is expected to be useful for application and driver
-- development because it allows any platform to expose an arbitrary or
-- customisable set of restrictions and features of a presentation engine.
-- This makes it a useful portable test target for applications targeting a
-- wide range of presentation engines where the actual target presentation
-- engines might be scarce, unavailable or otherwise undesirable or
-- inconvenient to use for general Vulkan application development.
