VkOreonworlds crashes when maximized

[aromanelli]

When trying to maximize the Vulkan demo, either by double-clicking on its title, or by clicking on the maximize button on the window title, the program crashes with the following console output ...

Exception in thread "main" java.lang.AssertionError: A surface has changed in such a way that it is no longer compatible with the swapchain, and further presentation requests using the swapchain will fail. Applications must query the new surface properties and recreate their swapchain if they wish to continuepresenting to the surface. at org.oreon.core.vk.util.VkUtil.vkCheckResult(VkUtil.java:61) at org.oreon.core.vk.swapchain.SwapChain.draw(SwapChain.java:298) at org.oreon.vk.engine.VkRenderEngine.render(VkRenderEngine.java:351) at org.oreon.core.system.CoreSystem.render(CoreSystem.java:40) at org.oreon.core.system.CoreEngine.render(CoreEngine.java:97) at org.oreon.core.system.CoreEngine.run(CoreEngine.java:71) at org.oreon.core.system.CoreEngine.start(CoreEngine.java:26) at org.oreon.examples.vk.oreonworlds.VkOreonworlds.main(VkOreonworlds.java:30)

I set a breakpoint at VkUtil.vkCheckResult(int), and the error code passed in is "-1000001004". Here's the info (screenshot of my IDE in debug mode) showing the vkCheckResult method being called, that genertes the assert failure ...

As an aside, the GLOreonworlds demo does not crash, but the world viewport size does not enlarge to meet the size of the window frame, that is now maximized. The world viewport keeps the pre-maximize size.

Yes I will fix this, it crashes because the swapchain and some Vulkan pipelines etc. which access screen width and height must be explicitly recreated after resizing the window.
