static void	image_cleanup (struct vk_bundle *vk, struct comp_swapchain_image *image)
	Free and destroy any initialized fields on the given image, safe to pass in images that has one or all fields set to NULL.

static void	really_destroy (struct comp_swapchain *sc)
	Swapchain destruct is delayed until it is safe to destroy them, this function does the actual destruction and is called from comp_swapchain_shared_garbage_collect.

	Helper to init a comp_swachain struct as if it was a create operation, useful for wrapping comp_swapchain within another struct.
xrt_result_t	comp_swapchain_import_init (struct comp_swapchain *sc, comp_swapchain_destroy_func_t destroy_func, struct vk_bundle *vk, struct comp_swapchain_shared *cscs, const struct xrt_swapchain_create_info *info, struct xrt_image_native *native_images, uint32_t native_image_count)
	Helper to init a comp_swachain struct as if it was a import operation, useful for wrapping comp_swapchain within another struct.
void	comp_swapchain_teardown (struct comp_swapchain *sc)
	De-inits a comp_swapchain, usable for classes sub-classing comp_swapchain.

	Create the shared struct.
void	comp_swapchain_shared_destroy (struct comp_swapchain_shared *cscs, struct vk_bundle *vk)
	Destroy the shared struct.
void	comp_swapchain_shared_garbage_collect (struct comp_swapchain_shared *cscs)
	Do garbage collection, destroying any resources that has been scheduled for destruction from other threads.
