virtual	~GPUSurfaceVulkanDelegate ()

virtual const vulkan::VulkanProcTable &	vk ()=0
	Obtain a reference to the Vulkan implementation's proc table.

virtual FlutterVulkanImage	AcquireImage (const SkISize &size)=0
	Called by the engine to fetch a VkImage for writing the next frame.

virtual bool	PresentImage (VkImage image, VkFormat format)=0
	Called by the engine once a frame has been rendered to the image and it's ready to be bound for further reading/writing.
