// BEGIN kbob
//    This is identical to https://vulkan-tutorial.com/Drawing_a_triangle/Swap_chain_recreation
//    as of 2018-06-13 except for code between the "BEGIN kbob" and "END kbob" comments.
//    The original code is still there but commented out with "//-".
//
//    Built with MoltenVK 1.1.73 and GLFW 20180519 for MacOS, the original never recreated
//    the swap chain.  It continued to draw at the original 800 by 600 resolution and scaled
//    the result to fit the resized window.
//
//    Also, according to GLFW doc, the glfwGetWindowSize() is not the right function to call.
