Description
The VK_EXT_headless_surface extension is an instance extension. It
provides a mechanism to create 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.

VkSurfaceKHR - Opaque handle to a surface object
Description
The VK_KHR_surface extension declares the SurfaceKHR object, and
provides a function for destroying SurfaceKHR objects. Separate
platform-specific extensions each provide a function for creating a
SurfaceKHR object for the respective platform. From the application’s
perspective this is an opaque handle, just like the handles of other
Vulkan objects.
