The Vulkan presentation surface for a GLFW window.

Surface asks GLFW to create the surface for a window handle on the instance behind a PhysicalDevice, and cleanup destroys it.

class Surface(physicalDevice: PhysicalDevice, windowHandle: Long)

class Surface(physicalDevice: PhysicalDevice, windowHandle: Long) {
    private val physicalDevice: PhysicalDevice

var vkSurface: Long = 0

init

    init {
        this.physicalDevice = physicalDevice
        MemoryStack.stackPush().use { stack ->
            val pSurface = stack.mallocLong(1)
            GLFWVulkan.glfwCreateWindowSurface(
                this.physicalDevice.vkPhysicalDevice.instance, windowHandle,
                null, pSurface
            )
            vkSurface = pSurface[0]
        }
    }

fun cleanup()

    fun cleanup() {
        KHRSurface.vkDestroySurfaceKHR(physicalDevice.vkPhysicalDevice.instance, vkSurface, null)
    }
